The method of delivery of the data is outside the scope of this document. TRK-2-34 is essentially a consolidation of the data that are currently contained in the TRK-2-15A, TRK-2-18, TRK-2-20, TRK-2-25, and TRK-2-30 products delivered to customers. 1.1.1 Applicability of This Release This module will supersede the TRK-2-15A module, as the MDAs are retired, and the TRK-2-25 module as the Radio Metric Data Conditioning (RMDC) process is retired. This release corrects typos and adds description of the file header format. Certain parameters may not be available in initial TRK-2-34 output. These parameters will be marked as invalid (using validity flags) in the data or not delivered (in the case of certain data types, such as Allan deviation and smoothed noise). 1.2 Revision and Control Revisions or changes to the information herein presented may be initiated according to the procedure specified in the Introduction to Document 820-013. 1.3 Relationship to Other DSMS Documents Currently, TRK-2-15A is generated by the Metric Data Assembly (MDA) of the DSCC Tracking Subsystem (DTK). In the Network Simplification Project (NSP) era, the MDAs will be replaced by the Uplink Tracking and Command Subsystem (UPL) and the Downlink Telemetry and Tracking Subsystem (DTT). As a result, TRK-2-15A will not be available. TRK-2-34 replaces TRK-2-25 as the archival format. TRK-2-20 and TRK-2-30 will continue to be available to the customers. 1.4 Applicable Documents [1] 820-062 DSMS Terms and Abbreviations (DSMS internal document, for reference only.)

The SFDU concept was developed by the Consultative Committee for Space Data Systems (CCSDS) to provide a standardized and internationally recognized methodology for information interchange. Because the SFDU concept evolved over time, the meaning of some terms has evolved. The definitions provided herein are intended to clarify the use of certain terms as they apply to this module: a) The term ASCII refers to the American Standard Code for Information Interchange, a seven-bit code for representing letters, digits, and symbols which has been standardized by the American National Standards Institute (Reference [8]). This code has been incorporated into the ISO code of the same nature (Reference [9]) which includes other symbols and alphabets. Since the ISO code is an eight-bit code, the ASCII code is embedded in an eight-bit field in which the most significant bit is set to zero. In this module, ASCII always refers to the seven-bit ASCII code embedded, as described, in an eight- bit field. When applied to a multi-byte field, it implies that each byte in the field contains an ASCII code. b) The term restricted ASCII (RA) refers to the subset of ASCII consisting of the codes for the twenty-six upper-case letters ('A'-'Z') and the ten decimal digits ('0'-'9'). When applied to a multi-byte field, it implies that each byte in the field contains an RA code. c) A label-value-object (LVO) is a data structure that is comprised of a label field and a value field. The label field provides for the data structure to be self-identifying and self-delimiting. The value field contains user-defined data in any format. The LVOs themselves are made up of a sequence of bytes. In this module, LVO is used in a generic sense to refer to any data structure with these attributes. d) An LVO may be a simple LVO or a compound LVO. If the value field of the LVO contains purely user data, it is a simple LVO. If the value field of the LVO contains purely LVOs, it is a compound LVO. The value field of a compound LVO consists of a sequence of one or more LVOs, each of which can be a simple or compound LVO itself. e) A standard formatted data unit (SFDU) is an LVO that conforms to a defined set of structure and construction rules, namely the specification in Reference [5] or the specification in Reference [6]. Unfortunately, the two specifications are slightly different, leading to two different definitions of what an SFDU is. The term DSN tracking SFDU (or, more simply, tracking SFDU) refers to the SFDU defined and controlled by this module. The DSN tracking SFDU conforms to the structure and construction rules specified in Reference [5]. It does not strictly conform to the internationally recognized SFDU structure and construction rules recommended by CCSDS in Reference [6]. f) A compressed header data object (CHDO), as defined in Reference [5], is an LVO. Its design is modeled on the SFDU concept, but a CHDO is not an SFDU. The CHDO derives its name from the fact that the label field of a CHDO is considerably shorter than the label field of an SFDU (four bytes instead of twenty). The CHDO provides a means of structuring user data with less overhead than would be required if an SFDU were used. However, with respect to SFDU structure and construction rules, a CHDO (or a sequence of CHDOs) is merely user data contained in the value field of an SFDU. g) The term type attribute is used to refer to the subfield(s) of an LVO label field that affect the self-identifying property of the LVO. Within the applicable domain, the type attribute is a unique reference to a description of the format and meaning of the data contained in the value field of the LVO. h) All of the LVOs described in this module contain a length attribute in their label field. The length attribute is a subfield of the LVO label field; it contains the length, in bytes, of the value field of the LVO. When interpreted in the context of the structure and construction rules specified in Reference [5], the length attribute affects the self-delimiting property of the LVO. The use of a length attribute is not the only means by which an LVO can be self-delimiting; Reference [6], for example, provides several mechanisms that do not rely on an explicit length. i) The term data type refers to the SFDU format code. This term is used when distinguishing between different data blocks. 1.5.2 Conventions The following conventions are used in this module: a) LVOs are defined as being made up of a sequence of eight-bit bytes, so data structures in this module are illustrated as a sequence of bytes. All data structures defined in this module must be an even number of bytes in length. Given a data structure that is N bytes in length, the first byte in the structure is drawn in the most top justified position and is identified as "byte 0." The following byte is identified as "byte 1" and so on, to "byte N-1" which is drawn in the most bottom justified position. Within each byte, the most significant bit is drawn in the most left justified position and is identified as "bit 1." The next most significant bit is identified as "bit 2" and so on, to "bit 8" which is drawn in the most right justified position. Any bit in a data structure is uniquely identified by specifying the byte within which it occurs and its position within that byte (e.g., "byte 5, bit 8"). b) Data structures are divided into fields, where a field is a sequence of bits. Fields are identified by specifying the starting and ending bits of the field. For fields that cross byte boundaries, bit 8 of byte M is more significant than, and is immediately followed by, bit 1 of byte M+1. A field may be divided into subfields in a similar manner. c) Several conventions for expressing the length of a data structure, or a part of a data structure, are used in this module. The length attribute of an LVO is always given in bytes and always refers to the length of the value field of the LVO (i.e., excluding the label field). d) In the data structure descriptions in this module, many fields are defined to contain a numerical value. Several different formats for expressing numbers are used, as follows: 1) Unsigned integer. An integer number is expressed in binary, using all bits of the field as necessary. Negative quantities cannot be expressed. For an n-bit field, the range of values that can be represented is from 0 to 2n-1. The number of bytes in the unsigned integer (m) is represented by a "-m" after the format statement. 2) Integer. An integer number is expressed in binary, using two's complement notation. For an n-bit field, the range of values that can be represented is from -2n-1 to 2n-1-1. The number of bytes in the integer (m) is represented by a "-m" after the format statement. 3) Restricted ASCII. Each decimal digit of an integer number is expressed by its corresponding RA code. The field must be an integral number of bytes in length. For multi-digit fields, the first byte of the field contains the most significant digit, the second byte contains the next most significant digit, and so on. If the number of digits is less than the number of bytes in the field, leading zeroes are used to fill the field. Negative quantities cannot be expressed. In an n-byte field, the range of values that can be represented is from 0 to 10n-1. The number of bytes in the Restricted ASCII string (m) is represented by a "-m" after the format statement. 4) IEEE Single. A 32-bit, single precision, IEEE floating point- format is used to express real numbers. Single precision floating-point numbers are expressed in the ANSI/IEEE standard (Reference [7]) single precision format with a sign bit, 8-bit exponent, and 23-bit mantissa. 5) IEEE Double. A 64-bit, double precision, IEEE floating-point format is used to express real numbers. Double precision floating-point numbers are expressed in the ANSI/IEEE (Reference [7]) standard double precision format with a sign bit, 11-bit exponent, and 52-bit mantissa. e) For fields defined to contain a constant value, the constant value will be enclosed in single quotes (e.g., '2') if the information is expressed in RA, and not so enclosed (e.g., 2) if the information is expressed in binary. f) Unless explicitly stated otherwise, fields defined as "reserved" are to be set to binary zero by the originator, and are to be ignored by the recipient. g) Time tags are in UTC, as received from the Frequency and Timing Subsystem (FTS) of the DSN: * 00:00:00 is second 0.0. * 23:59:59 is second 86399.0. * Leap second is 86400.0. h) The term "UPL-DTT antenna" refers to antennas that have UPL and DTT equipment (currently 34m HEF, 34m BWG, and 70m antennas). The term "non-UPL- DTT antenna" refers to antennas that do not have this equipment (currently 26m antennas and DSS-27). 1.6 Abbreviations Abbreviations used in this document are defined with the first textual use of the term.

The resulting data will be placed into the TRK-2-34 and TRK-2-18 products. Validated/corrected data are available to (a) remote customers as TRK-2-34 files, and (b) JPL AMMOS customers as files, stream-type queries, or broadcast streams. The file format is described in Appendix B. This interface does not describe the transfer mechanisms for the delivery of the data to the customers; they are described, respectively, in References [3c] and [3d]. This processing is done in the AMMOS system. It includes the software tools that are used to perform radio metric data processing, validation, correction, and visualization, and to generate the tracking data file products. The function of the processing is to process, generate, and deliver radio metric data to projects and end users to support spacecraft navigation and scientific study. Listed below are the documents and 820-013 interface modules that define specific fields in the TRK-2-34 headers: Reference [3a]: DSN spacecraft ID, AMMOS mission ID Reference [10]: station ID Reference [4]: originator ID, last modifier ID 2.2 Operational Concept Users provide spacecraft configuration data (such as transponder number, spacecraft oscillator frequency values, etc.) and light time data. The user also specifies data delivery options (such as data decimation rate). This data, along with the DSN physical data maintained in internal tables, are combined with the raw measurements from the DSN to generate the radiometric data described by this document. TRK-2-15A data will continue to be produced by DSSs until the Metric Data Assembly (MDA) has been completely retired. The existing Radio Metric Data Conditioning (RMDC) software will continue to be used until the TRK-2-15A data are no longer produced. Parameters and data types that require predicted values, such as prefit residuals and Allan deviation, will not be available if the trajectory data for generating the predicted values is not available. If this happens, the parameter status will be marked as invalid (using validity flags) and the data types will not be generated. 2.3 Equipment All equipment used in the measurement or generation of tracking data get their frequency and timing references from the Frequency and Timing Subsystem (FTS) of the DSN. The non-UPL-DTT antennas have a mixture of tracking equipment. The 26m subnet uses the Metric Pointing Assembly (MPA). DSS-27, a 34m antenna, uses the Metric Tracking Assembly (MTA). Arraying at a complex is done with the Full Spectrum Processing Subsytem (FSP). Section 3 Detailed Interface Description 3.1 Data Definition Viewed as a compound LVO, the value field of the tracking data SFDU contains two LVOs, an aggregation CHDO and a tracking data CHDO. The aggregation CHDO is a compound LVO; its value field contains two simple LVOs, a primary CHDO and a secondary CHDO. The aggregation CHDO exists solely for the purpose of allowing the primary and secondary CHDOs to be grouped together and treated as a single LVO. The value fields of the primary and secondary CHDOs contain annotation data (identification, configuration, status, and performance parameters) that pertain to the data in the tracking data SFDU. The tracking data CHDO is a simple LVO; its value field contains the actual tracking data. +---------------------------------------------+ L| Tracking Data SFDU | +-+ +---------------------------------------+| | L| Aggregation CHDO || | +-+ +---------------------------------+|| | | L| Primary CHDO ||| | | +-+ ||| | | V| ||| | V| +---------------------------------||| | | L| Secondary CHDO ||| | | +-+ ||| V| | V| ||| | +---------------------------------------|| | L| Tracking Data CHDO || | +-+ || | | || | | || | | || | V| || | | || | | || | | || +-------------------------------------------+ L = label field V = value field Figure 3-1.

Physical Layout of the Tracking Data SFDU 3.1.1 Tracking Data SFDU Label Bytes 0 through 19 of the tracking SFDU contain the SFDU label field. The format and content of the SFDU label are defined in Table 3-1. The concatenation of Bytes 0 through 3, and 8 through 11, constitutes the type attribute of the SFDU; in CCSDS parlance, this concatenated field is known as the Authority and Description Identifier (ADID). Bytes 12 to 19 constitute the length attribute. |===========================================================================| | Table 3-1.

Uplink data are the validated uplink phases from the UPL-DTT antennas and the uplink ramps. Downlink data are the validated downlink phases from the UPL-DTT antennas. Derived data are the data from the non-UPL-DTT antennas, and the processed doppler, range and DRVID data from the UPL-DTT antennas. Interferometric data are the VLBI data. Filtered data are the measurements derived from the accumulated downlink carrier phase data (smoothed noise and Allan Deviation) and are only available for UPL-DTT antennas. The data types are as follows: * Uplink Data * Uplink Carrier Phase (data type 0) * Uplink Sequential Ranging Phase (data type 2) * Uplink PN Ranging Phase (data type 4) * Ramp (data type 9) * Downlink Data * Downlink Carrier Phase (data type 1) * Downlink Sequential Ranging Phase (data type 3) * Downlink PN Ranging Phase (data type 5) * Derived Data * Doppler Count (data type 6) * Sequential Range (data type 7) * Angle (data type 8) * DRVID (data type 11) * PN Range (data type 14) * Tone Range (data type 15) * Carrier Frequency Observable (data type 16) * Total Count Phase Observable (data type 17) * Interferometric Data * VLBI (data type 10) * Filtered Data * Smoothed Noise (data type 12) * Allan Deviation (data type 13) 3.1.5.1 Uplink Data CHDOs There are four Uplink Data CHDOs: Uplink Carrier Phase (data type 0), Uplink Sequential Ranging Phase (data type 2), Uplink PN Ranging Phase (data type 4), and Ramp (data type 9).

Appendix A Notes 1. Seconds to HH:MM:SS (UTC) format: 0.0 => 00:00:00 86399.0 => 23:59:59 86400.0 => Leap second 2. This offset (transmit_time_tag_delay) should be added to the time tag. It is used to compensate for differences in the time tag point and the antenna radiation point. 3. This offset (rcv_time_tag_delay) should be subtracted from the time tag. It is used to compensate for differences in the time tag point and the antenna radiation point. 4. Array delay (array_delay) is included in the station calibration value (stn_cal) measurement and should be subtracted from the time tag. 5. Spacecraft transponder lock (scft_transpd_lock), spacecraft transponder number (scft_transpd_num), spacecraft two-way non-coherent (TWNC) status (scft_twnc_stat), and spacecraft oscillator type (scft_osc_type) are obtained from spacecraft engineering data, which may not be available. 6. Spacecraft oscillator frequency (scft_osc_freq) is obtained from spacecraft project supplied data. 7. Spacecraft transponder delay (scft_transpd_delay) is based on spacecraft and configuration data supplied from spacecraft project. In the future, it may be based on engineering data from the spacecraft. This is the delay the ranging signal experiences through the spacecraft. 8. PHASE = HI * 232 + LO + FRAC * 2-32 , where, HI = ul_hi_phs_cycles, or phs_hi_x (with x = 0 through 9), phs_hi_avg, or dop_cnt_hi, or total_cnt_phs_ob_hi LO = ul_lo_phs_cycles, or phs_lo_x (with x = 0 through 9), or phs_lo_avg, or dop_cnt_lo, or total_cnt_phs_obs_lo FRAC = ul_frac_phs_cycles, or phs_frac_x (with x = 0 through 9), or phs_frac_avg, or dop_cnt_frac, or total_cnt_phs_obs_frac 9. Not applicable. 10. If hardware at station allows splitting the uplink and downlink ranging delays, the value will be included here. Otherwise, it is set to 0.0. 11. Measured code value (ul_rng_phs) and measured range value (dl_rng_phs) are the phase of the ranging signal at the time tag. 12. T1 setting (t1) is the length of time that the first component (the clock) is transmitted. 13. T2 setting (t2) is the length of time that each subsequent component is transmitted. 14. T3 setting (t3) is the length of time that the clock is transmitted for each DRVID measurement. 15. Component frequency is F_EXC * 2-(n+2), where n is the component number and F_EXC is the exciter reference signal (see note 17). 16. Chopping modulates the ranging signal with a subcarrier at the chop component frequency (chop_comp_num), for all components after and including the chop start component (chop_start_num). For example, if the chop start component value is 6 and the chop component is 5, all components from 6 on will be modulated with component 5. If the chop value is zero, all components starting with 15 and larger are chopped with the clock component. 17. The exciter reference frequency (F_EXC) is defined as follows: F_EXC = FRQ_UP * (exc_scalar_num/exc_scalar_den) where FRQ_UP is the uplink carrier frequency. 18. Sequential ranging cycle time is defined as follows: rng_cycle_time = (t1 + 2) + (last_comp_num - first_comp_num) * (t2 + 1) + num_drvid * (t3 + 2) + 1 19. The PN ranging code is a combination of multiple sequences logically combined. The code state is the particular bit (or chip) in the sequence, plus the phase of that chip at the time tag. For a component length L, and a subsequence state S, the code state C is related to L and S by: S = C mod L 20. PN chip rate = F_EXC / clk_divider 21. The first "n" bits (where n is the length specified in len_seqj) define the PN subsequence, e.g., a value of 46 for def_seq4 gives the following sequence: 0101110, which will have a value of 7 in len_seq4. 22. Code length (pn_code_length) equals the result of multiplying the lengths of all of the subsequences together. 23. PN cycle time is 16 * clk_divider * pn_code_length. 24. One Range Unit (RU) is defined as: 1 RU = (exc_scalar_den / exc_scalar_num) / (16 * FRQ_UP) where FRQ_UP is the uplink carrier frequency. Range is measured in RU to give a stable reference measurement when the uplink is being ramped. 25. If carrier is suppressed (carr_resid_wt = 0.0), then the data power is used for the carrier tracking. 26. Doppler noise (dop_noise) is the standard deviation of the detrended downlink frequency residuals. The detrending is the removal of the least squares linear fit of the frequency residuals over the sample period. For the Downlink Carrier Phase data type (data type 1) and Doppler data type (data type 6), the sample period is 1 second. For the Carrier observable data type (data type 16), the sample period is sample integration time (obs_cnt_time) times the number of samples (num_obs). The equation for the Doppler noise is: dop_noise = sqrt((1 / N) * sum{F(I * t) - FL(I * t)}^2 - [(1 / N) * sum{F(I * t) - FL(I * t)}]^2) where F is the frequency residual, FL is the linear least squares fit of F, t is the spacing between points, and the sums are taken over I = 1 to N. 27. carr_resid_wt is the weight value applied to residual phase error in carrier tracking; suppressed carrier weight is 1.0 minus this value, e.g., phi_err = carr_resid_wt * phi_err_resid + (1 - carr_resid_wt) * phi_err_suppressed 28. Figure of Merit (FOM) (figure_merit) is the estimate of the probability of successfully acquiring all of the lower components (other than the clock component). It is expressed as a percentage (0.0 to 100.0). For sequential ranging, it is defined as: figure_merit = [1 + Erf{-sqrt(prn0 * t2)] ^ (rng_comp2 - rng_comp1) / 2 ^ (rng_comp2 - rng_comp1) where Erf(*) is the error function. For PN ranging, it is defined as: figure_merit = prod((1 / sqrt(pi)) * integral{exp(-x ^ 2) * [[{1 + Erf (x + (Cmax - Cmin) * sqrt(int_time * prn0))} / 2 ] ^ [len(i) - 1]] * dx}) where Cmin and Cmax are the minimum and maximum correlation values for each subsequence, len(i) is the length of the ith subsequence (2, 7, 11, 15, 19, and 23), prod is taken over i = 1 to 6, and integral is taken over minus infinity to plus infinity. 29. Range residual accuracy depends on the accuracy of the predicts and is rarely better than 1 microsec (1000 RU). 30. DRVID (drvid) stands for Differenced Range Versus Integrated Doppler. It is a measurement of the difference between the group and phase delay of the media. The measurement (at time tag TT) is the difference between two consecutive measured range points (i.e., points separated by the cycle time) minus the scaled difference in the uplink and downlink carrier phases over the same time period. The measurement is defined below: D_RNG = (meas_rng(TT) - meas_rng(TT - rng_cycle_time)), mod rng_modulo I_DOP = {(phi_T(TT) - phi_T(TT - rng_cycle_time)) - (scft_transpd_turn_den / scft_transpd_turn_num) * (phi_R(TT) - phi_R(TT - rng_cycle_time))} drvid = D_RNG - [16 * (exc_scalar_num / exc_scalar_den) * I_DOP mod rng_modulo] This has previously been called pseudo-DRVID, since the measurement does not require increasing the cycle time by adding additional clock transmissions during the measurement. The method of using additional clock cycles does not measure the carrier phase over the same period of time as the range measurement; this is why the pseudo-DRVID implementation was selected. 31. Slipped cycles (slipped_cycles) are estimated by processing the frequency residuals in a software-simulated, digital phase-locked loop and comparing the phase error with slip conditions. This estimate is subject to degradation during high noise conditions. The slipped cycles value is the number of cycle slips (both positive and negative) detected in this manner, for the sample interval. 32. Delta Frequency/Frequency (delta_ff) is the change in downlink frequency since the last sample, divided by the downlink frequency at this time tag. 33. A set of measurements is provided in the Received Carrier and Total Count Phase Observables data types (data types 16 and 17). For each set, a number of measurements (num_obs) and a time interval (obs_cnt_time) are provided. The first measurement is at the time tag reported in the header; the ith measurement (i = 1 to number of measurements) is at the time tag (TT) plus (i-1) * obs_cnt_time. The interval of time covered by the measurements is TT - obs_cnt_time to TT + (number of measurements - 1)* obs_cnt_time. 34. The Doppler Count is defined as difference in the uplink carrier phase (generated by integrating ul_freq), scaled by the spacecraft transponder turn around ratio, minus the downlink carrier phase plus a bias term (generated by integrating dop_cnt_bias_freq). The bias term is used to keep the Doppler Count a positive value. For UPL-DTT antennas, the ul_freq value is determined by the downlink frequency; for other antennas, it depends on the equipment configuration. The time tag of the ith measurement (i equals 1 to 10) is TT + (i - 1) * 0.1. The time tag is the end of the Doppler Count interval. Doppler Count = - (phi_R,i) + ((scft_transpd_turn_num/scft_transpd_turn_den) * ul_freq + dop_cnt_bias_freq )* (TimeI - Timestart) 35. The Received Carrier Frequency Observable is defined as the negative of the difference in the downlink phase at the end of the interval and the downlink phase at the start of the interval, divided by the interval time. The time tag point of the difference is the middle point of the count time interval (note that this means that the time tag may be on the half second). The time tag of the ith measurement (i equals 1 to num_obs) is TT + (i - 1.0) * obs_cnt_time. Observable = - (phi_i - phi_i-1) / obs_cnt_time 36. The Total Count Phase Observable is the difference between the downlink carrier phase at the measurement time tag and the downlink carrier phase at a starting point (a running integration). The time of the starting point is given by total_cnt_phs_st_year, total_cnt_phs_st_doy, and total_cnt_phs_st_sec. The starting point changes whenever something causes the carrier lock to be broken, such as spacecraft mode changes or downlink loss of lock. The time tag of the ith measurement (i equals 1 to num_obs) is TT + (i - 1) * obs_cnt_time. Observable = - (phi_i - phi_start) The value reported is the negative of the observable, e.g.: Reported Observable = (phi_i - phi_start) 37. Sequential ranging ambiguity (rng_modulo) in Range Units is defined as 2^(6+last_comp_num). 38. Sequential measured range (meas_rng) is the difference between the uplink ranging phase (ul_rng_phs) and the downlink ranging phase (dl_rng_phs) (for UPL-DTT antennas). For non-UPL-DTT antennas, the Sequential Ranging Assembly range value is used. The difference is the positive modulo of rng_modulo value. This measurement is not corrected for any calibration issues. 39. Range Observable is defined as the measured range (meas_rng) minus the calibration correction. This observable is valid for both UPL-DTT and non- UPL-DTT antennas and is supplied to maintain compatibility between the two. The calibration correction is defined as: Correction = (ul_stn_cal - transmit_time_tag_delay) + ul_zheight_corr + scft_transpd_delay + (dl_stn_cal - rcv_time_tag_delay - array_delay) + dl_zheight_corr 40. If the measured uplink calibration value (ul_stn_cal) as reported in the uplink range SFDUs is non-zero, then the uplink calibration value (ul_stn_cal) in the derived SFDUs for sequential and PN range is this value. Otherwise, it is one-half of the station calibration value (stn_cal). If the value is invalid, the parameter is set to -1.0. 41. If the measured downlink calibration value (dl_stn_cal) as reported in the downlink ranging SFDUs is non-zero, then the downlink calibration value (dl_stn_cal) in the derived SFDUs for sequential and PN range is this value. Otherwise, it is one-half of the station calibration value (stn_cal). ). If the value is invalid, the parameter is set to -1.0. 42. The uplink frequency (ul_freq) is provided for computing the Range Unit definition for those antennas that do not support ramped uplinks (i.e., no Data Type 9). 43. Range noise (rng_noise) is the standard deviation of up to the last 100 (i.e., if more than 100 data points exist, only the last 100 are used) range residuals, detrended by removing the least squares linear fit of the data. The equation for the Range noise is (R is the range residual, RL is the linear least squares fit of R, N is the number of points (up to 100), and t is the spacing between points): rng_noise = sqrt((1/N) * sum{R(I*t) - RL(I*t)}^2 - {(1/N) * sum[R(I*t) - RL(I*t)]}^2) where the sums are computed over I=(1,N). 44. DRVID noise (drvid_noise) is the standard deviation of up to the last 200 (i.e., if more than 200 data points exist, only the last 200 are used) DRVID values. The equation for the DRVID noise is (D is the DRVID residual, N is the number of points (up to 200), and t is the spacing between points): drvid_noise = sqrt((1/N) * sum{D(I*t)}^2 - {(1/N) * sum{D(I*t)}}^2) where the sums are computed over I=(1,N). 45. PN ranging ambiguity (modulo value) is defined as: rng_modulo = 16 * clk_divider * pn_code_length 46. PN measured range value (meas_rng) is the difference between the uplink ranging phase (ul_rng_phs) and the downlink ranging phase (dl_rng_phs). It is only available from the UPL-DTT antennas. The difference is the positive modulo of the rng_modulo value. This measurement is not corrected for any calibration issues. 47. Smoothed noise is the standard deviation of the detrended downlink frequency residuals. The detrending is the removal of the least squares linear fit of the frequency residuals over the sample period. Estimates are computed for 0.1, 1, 10, 100, 200, and 600-second intervals. The minimum sample period is 180 seconds, the maximum is 10,800. The standard deviation is computed over 18 points; if the number of points in the reporting period is more than 18 (e.g., 0.1-second and 1.0-second), the 18-sample standard deviations are averaged. The equation for the Smoothed noise is (F is the frequency residual, FL is the linear least squares fit of F, and t is the time spacing between points): NOISE = sqrt((1/18) * sum{F(I*t) - FL(I*t)}^2 - {(1/18) * sum{F(I*t)-FL(I*t)}}^2) 48. Since the record is generated every 180 seconds and each integration needs 18 points, the longer integrations will not be updated every time. The new_xxx flags are used to indicate which integrations have been updated. 49. Allan deviation is computed for interval (TAU) values of 0.1, 1, 10, 100, and 1000 seconds. The record is nominally output once every 1000 seconds. The frequency residuals are used for the computation (to remove the known motion effects, such as earth rotation). The result is normalized to DSN channel 14 (2295 MHz for S-band, 8415 MHz for X-band, and 31.977 GHz for Ka- band); this value is referred to as F0. The number of points, N, is equal to the integration time, INT_TIME, divided by TAU. delta_F_TAU / F = sqrt((1/2N) * sum{F(TAU*I) - F(TAU*(I-1))}^2) / F0 50. percent_data_used indicates if some data in the integration period was not used (e.g., carrier was out of lock). 51. If a record is generated due to a change in system status (e.g., receiver mode change), the report time will be short of the normal 1000 seconds, so the longer integrations may not have a new point computed. The new_xxx flags are used to indicate which integrations have been updated. 52. Some hardware (ground or spacecraft) may invert the ranging modulation. invert allows these inversions to be corrected on the uplink or downlink processing. 53. Loop Type (carr_loop_type) is the number of poles in the carrier phase locked loop transfer function. The number poles (or order) of the loop filter is the Loop Type minus one. For each increment in the Loop Type, one higher order derivative of Doppler is tracked out to zero (Type 1 tracks out phase offsets, Type 2 tracks out frequency errors, Type 3 tracks out frequency rate errors). 54. The time offset (prdx_time_offset) is a value added to the current time when generating the predicted frequency from the frequency predicts (F(t)). Thus, the predicted frequency (F_PRED), at time t, used by the tracking loop is: F_PRED = F(t + prdx_time_offset) 55. The frequency offset (prdx_freq_offset) is a value added to the frequency value generated from the frequency predicts (F(t)). Thus, the predicted frequency (F_PRED), at time t, used by the tracking loop is: F_PRED = F(t) + prdx_freq_offset 56. Correlation validity (correl_vld_flag) is reported by the downlink ranging equipment. It is an estimate of whether or not the clock component is properly aligned with the received ranging signal (it measures the power in the inphase and quadrature signals when correlating the lower components - if the clock is properly aligned, the power in the inphase signal is much greater than the quadrature signal). 57. The Angles Validity Flag (ang_vld_flag) is set by the tracking equipment to indicate whether or not the angle data is valid. 58. The signal level (rcv_sig_lvl) is either provided by the tracking station (non-UPL-DTT antennas), or derived from other parameters (UPL-DTT antennas). For the 34m and 70m antennas, the derivation is as follows: Signal Level = P_N0 - (K_DB + 10 * log10(system_noise_temp)) Where K_DB is Boltzmann's constant (-198.6 dBm/Hz/k), system_noise_temp is the system noise temperature, and P_N0 is either pcn0 (car_resid_wt > 0.0) or pdn0 (car_resid_wt = 0.0). 59. The In Phase Time (transmit_inphs_time or rcv_inphs_time) is the time point that the ranging modulation reference was initialized to zero phase. It is used for three-way ranging cases. It is seconds of day offset from the block time tag. 60. Distance (in time) to the phase center of the antenna that is not included in the station calibration. Included in this value is the delay to and from the test translator, the delay inside the test translator, the delay from the range calibration coupler to the phase center of the antenna, and the delay between the main antenna dish and the subreflector. Z-height is expressed in seconds, so it must be converted to Range Units before it is included in the Range Observables. The uplink part of this compensation (which is the delay from the point that the test translator taps off of the uplink path to the phase center) is provided in ul_zheight_corr and the downlink part (which is the delay from the phase center to the point where the test translator joins the downlink path, minus the delay of the test translator path) is in dl_zheight_corr. 61. When downlink carrier data is received, it reports the configuration that was used at the tracking station for the source of the downlink (e.g., three-way with DSS 65). However, that may not be the actual spacecraft mode (for example, the spacecraft may have been locked to an uplink from DSS 54, but the receiving station did not have any three-way predicts for DSS 54, so the predicts for DSS 65 were used instead). A validation is done to determine the actual spacecraft mode and is reported in the validated uplink station (vld_ul_stn) and validated doppler mode (vld_dop_mode) fields of the downlink data secondary CHDO. 62. The Carrier and Total Phase Count Pre-fit Residual Tolerance flags (carr_prefit_resid_tol_flag and total_phs_cnt_prefit_resid_tol_flag) indicate whether or not the pre-fit residuals are within the tolerance (carr_prefit_resid_tol_value and total_phs_cnt_prefit_resid_tol_value) set by the spacecraft project. The prefit residual flags (carr_prefit_resid_tol_flag and total_phs_cnt_prefit_resid_tol_flag) are set to Not Applicable if the prefit residual validity flags (carr_prefit_resid_vld_flag and total_phs_cnt_prefit_resid_vld_flag) indicate invalid. 63. The Range Residual Tolerance flag (rng_resid_tol_flag) indicates whether or not the range residual is within the tolerance (rng_resid_tol_value) set by the spacecraft project. 64. The DRVID Tolerance flag (drvid_tol_flag) indicates whether or not the DRVID value is within the tolerance (drvid_tol_value) set by the spacecraft project. 65. The Pr/N0 Residual Tolerance flag (prn0_resid_tol_flag) indicates whether or not the Pr/N0 residual is within the tolerance (prn0_resid_tol_value) set by the spacecraft project. 66. The Range Sigma Tolerance flag (rng_sigma_tol_flag) indicates whether or not the range sigma (noise) is within the tolerance (rng_sigma_tol_value) set by the spacecraft project. 67. The Range Validity flag (rng_vld_flag) indicates that the range data is valid if the receiver is in-lock, if the Correlation Validity flag (correl_vld_flag) indicates valid data, and the FOM (figure_merit) is above its tolerance value (fom_tol_value). 68. The Range Configuration Change flag (rng_config_flag) is set whenever the system determines the microwave configuration has changed since the ranging calibration was done. 69. Note 69 has been deleted. 70. The Metrics Validity flag (metrics_vld_flag) indicates whether or not the downlink ranging equipment was able to process the ranging data to get a measurement of range and DRVID (for example, the pass may have been three-way and the uplink data was not available). 71. Note 71 has been deleted. 72. Currently, the equipment that performs the tone range measurement includes the corrections for the calibration and the Z-height correction in the reported range; however, these values are not reported by the station. Thus, stn_cal, ul_zheight_corr, dl_zheight_corr are set to 0.0. The range observable (rng_obs) is equal to meas_rng minus the spacecraft transponder delay scft_transpd_delay. If the equipment at the station is corrected, the values will be non-zero. 73. The Modification Time items (day and msec) are set to 0 when the block is first created. If any data in the block is changed, the items are set to the time of the modification. The time is expressed as the time (UTC) since the epoch of January 1, 1958. The time is represented as days since the epoch and milliseconds of the day. 74. The record creation time is the time when the data processing task first creates the record. It is expressed as the time (UTC) since the epoch of January 1, 1958. The time is represented as days since the epoch and milli- seconds of the day. 75. The In Phase Time (transmit_inphs_time_xxx or rcv_inphs_time_xxx, where xxx is year, doy, or sec) is the time point (UTC) that the ranging modulation reference was initialized to zero phase. It is used for three-way ranging cases. When reported from the DSN stations, it is reported as an absolute time (see note 59 regarding its other format). 76. The Downlink Range Observable (rng_obs_dl) is defined as the calibration correction minus the downlink ranging phase. It is only valid for UPL-DTT antennas. The calibration correction is defined as: Correction = (ul_stn_cal - transmit_time_tag_delay) + ul_zheight_corr + scft_transpd_delay + (dl_stn_cal - rcv_time_tag_delay - array_delay) + dl_zheight_corr 77. Downlink range observable validity flag (rng_obs_dl_vld_flag) indicates whether or not the Downlink range observable item (rng_obs_dl) is valid. It will be invalid if the data is for a non-UPL-DTT antenna. 78. The Clock Offset Epoch Time (clk_off_epoch_year, clk_off_epoch_doy, and clk_off_epoch_sec) is the time (UTC) that the two clock offsets (clk_off_1 and clk_off_2) where measured . 79. The uplink data is only valid if the validated spacecraft coherency (vld_scft_coh) indicates an uplink (value of 1 or 3). 80. The DRVID computation is done by the data processing task in AMMOS. 81. This computation is done at the station. The metrics validity flag (metrics_vld_flag) indicates its validity. 82. For DTT data, the downlink band is assumed to be correct. For non-DTT data, a validation is done. In the case of 26m stations, which use the two acquisition aid antennas (for both S- and X-band), if the downlink band cannot be definitively determined, the value gets set to "S or X". 83. The carrier lock status (carr_lock_stat) for non-DTT antennas is inferred from other values. 84. The count time (interval), Tc, that is used to form an observable is constrained by the sample interval. 85. A set of measurements is provided in the Doppler Count data type (data type 6). For each set, a number of measurements (10 or 1) and a time interval (sampl_time) are provided. The first measurement is at the time tag reported in the header; if there are 10 measurements, the ith measurement (i = 1 to number of measurements) is at the time tag (TT) plus (i-1) * 0.1. The interval of time covered by the measurements is TT to TT + (number of measurements - 1)* 0.1. 86. Until prefit residual values (rng_dl_prefit_resid, rng_prefit_resid, and carr_prefit_resid) are delivered, they will be indicated as invalid by setting their residual flags (rng_dl_prefit_resid_vld_flag, rng_prefit_resid_vld_flag, and carr_prefit_resid_vld_flag, respectively) to a value of 0. 87. Arraying is done using the Full Spectrum Processor (FSP). There are two FSPs per complex. 88. This field only pertains to the Doppler (Data Type 6), the Received Carrier Frequency Observables (Data Type 16) and the Total-Count Phase Observables (Data Type 17) data CHDOs. Otherwise, when not applicable, the field is set to 0. In the case of Data Types 16 and 17, this field describes the compression interval, which ranges from 0.1 through 3600.0 seconds. In the case of Data Type 6, this field describes the sample interval. 26m stations are capable of producing tracking data at sample intervals of 0.1, 1, 10, or 60 seconds. UPL/DTT stations produce tracking data at a 0.1 second interval. Appendix B File Format B.1 LVO Structure of Files When the data defined by this document are stored in a file, the file is wrapped with an attached header. The file consists of nested LVOs, including a catalog LVO (known as the K-object LVO) and a data LVO (known as the I- object LVO). The catalog LVO contains the meta-data needed to catalog the actual tracking data. The data LVO consists of CHDO SFDUs defined in Section 3. The LVO structure of a file is depicted in Figure B-1. Further details on the contents of the label and value fields of each LVO are provided in the following subsections. +---------------------------------------------+ L| Primary SFDU Label | +-+ +---------------------------------------+| | L| K-Object Label || | +-+ | | V| Catalog Information || | | End Marker || V| +---------------------------------------|| | L| I-Object Label || | +-+ || | V| CHDO SFDUs || | | || . . .. . . .. . . .. | | EOF || +-------------------------------------------+ L = label field V = value field Figure B-1. LVO Structure of Files B.2 Physical Layout of Files The physical layout of the TRK-2-34 file is shown in Figure B-2. The length in bytes is 88+M+L, where M is the length of the catalog field and L is the length of the CHDO SFDUs. The structure is divided into three main parts: * primary label of the entire SFDU (Table B-1 describes the primary label.) * K-header. The K-header (or K-object) consists of the K-header SFDU label (or K-object SFDU label), catalog information, and an end marker. The catalog information consists of meta-data for cataloging the SFDU file. The meta-data are in the form of keyword-value pairs (hence, the "K" for keyword). (Tables B-2 and B-3 describe the K-header.) * I-object. The I-object (where "I" stands for information) contains the CHDO SFDUs defined by Section 3, preceded by an I-object SFDU label. (Table B-4 describes the I-object SFDU label.)

This value field of the LVO contains the set of parameters and values, in = format, of attributes that are pertinent to the file data. Each line is terminated with a carriage return (ASCII decimal code 13, written as or Ctrl-M), and a line feed (ASCII decimal code 10, written as or Ctrl-J). The values must conform to the standard ASCII character set (32 through 127 decimal). In addition, the values should be in upper case, except for the NOTE field. |===========================================================================| | Table B-3.

The marker field delimits the end of the catalog LVO. The 20 byte field is the following ASCII string: "CCSD$$MARKER$T-2-34$". B.2.3 I-Object SFDU Label Bytes 60+M to 79+M are the label field for the I-Object SFDU. The 20 bytes are defined below in Table B-4. |===========================================================================| | Table B-4. I-Object SFDU Label | |===========================================================================| | Byte | Data Item - Description and Units | Format | Range | |======+==============================================+==========+==========| | 0-3 |Control authority identifier (CAID). This CAID|Restricted| 'NJPL' | | |field indicates that the data description | ASCII-4 | | | |information (referred to at bytes 8 to 11) for| | | | |this SFDU is maintained and disseminated by | | | | |the NASA/JPL control authority. | | | |------+----------------------------------------------+----------+----------| | 4 |SFDU version identifier. This version field |Restricted| '3' | | |indicates how this I-object SFDU label is | ASCII-1 | | | |delimited. The value of '3' indicates that | | | | |this LVO can be delimited by marker, EOF (end | | | | |of file), or length. In this case, the actual| | | | |delimiter is by EOF, as indicated by byte 6. | | | | |The value of '3' is required per PDS Stds | | | | |Ref., p.16-7. Also refer to MGDS User's | | | | |Guide/Working with File Data (JPL D-6060), | | | | |Ch.2; AnyCatalog, p.4-12 to 4-13. | | | |------+----------------------------------------------+----------+----------| | 5 |SFDU class identifier. This class identifier |Restricted| 'I' | | |field gives a high-level classification of the| ASCII-1 | | | |content of the value field of this LVO (i.e., | | | | |the I-object LVO). The value of 'I' indicates| | | | |that the value (V) field of this LVO contains | | | | |an I-object (or information object.) The | | | | |value of 'I' is required per PDS Stds Ref., | | | | |p.16-7. Also refer to MGDS User's | | | | |Guide/Working with File Data (JPL D-6060), | | | | |Ch.2; AnyCatalog, p.4-12 to 4-13. | | | |------+----------------------------------------------+----------+----------| | 6 |Delimiter identifier. This delimitation |Restricted| 'F' | | |this I-object SFDU label uses for its last | ASCII-1 | | | |eight bytes. A value of 'F' indicates that | | | | |this label ends with the value specified in | | | | |bytes 12 to 19, which implies that the | | | | |I-object ends with an EOF marker. The value | | | | |of 'F' is required per PDS Stds Ref., p.16-7. | | | | |Also refer to MGDS User's Guide/Working with | | | | |File Data (JPL D-6060), Ch.2; AnyCatalog, | | | | |p.4-12 to 4-13. | | | |------+----------------------------------------------+----------+----------| | 7 |Reserved. This byte is a spare field. |Restricted| '0' | | | | ASCII-1 | | |------+----------------------------------------------+----------+----------| | 8-11 |Data description package identifier. This |Restricted| 'T234' | | |field uniquely identifies (for the specified | ASCII-4 | | | |Control Authority, i.e., NJPL, per bytes 0 to | | | | |3) the data object [or value (V) field of this| | | | |LVO]. | | | |------+----------------------------------------------+----------+----------| | 12-19|Length attribute of the SFDU. The end of this| Standard |'00000001'| | |LVO is designated by marker - in this case, an| ASCII-8 | | | |EOF marker. The EOF marker is specified in | | | | |this I-object SFDU label as '00000001.' Note | | | | |that the EOF marker terminating the I-object | | | | |serves a dual purpose in that it also | | | | |terminates the entire file, per bytes 12 to 19| | | | |of the primary SFDU label. The value of | | | | |'00000001' is required per PDS Stds Ref., | | | | |p.16-7. Also refer to MGDS User's | | | | |Guide/Working with File Data (JPL D-6060), | | | | |Ch.2; AnyCatalog, p.4-12 to 4-13. | | | |===========================================================================| B.2.4 Binary Data Object Starting at byte 80+M (M being the length of the catalog field) is the binary data object. The binary data object of the file contains a series of CHDO SFDUs in time-sorted order. That is, given a file containing different data types, all the data types are interleaved based on time. The CHDOs are defined in Section 3. The total length of the binary data object is L bytes. B.2.5 End of File (EOF) Starting at byte 80+M+L (M being the length of the catalog field and L being the length of the binary data object) is the end of the file (EOF) marker. This 8 byte marker is defined in the Primary Label field, bytes 12 to 19. The value of the EOF marker is '00000001'.
