3 MaRS, RSI and VeRa Volumes and Datasets Organizations, Formats and Name 
Specifications
3.1 Definitions and General Concept
3.1.1. Definitions
3.1.1.1.Data Product
A labeled grouping of data resulting from a scientific observation. Examples 
of data products include spectrum tables, and time series tables. A data 
product is a component of a data set.
3.1.1.2. Data Set
The accumulation of data products, secondary data, software, and 
documentation, that completely document and support the use of those data 
products. A data set is part of a data set collection.
3.1.1.3. Data Set Collection
A data set collection consists of data sets that are related by observation 
type, discipline, target, or time, and therefore are treated as a unit, 
archived and distributed as a group (set) for a specific scientific objective 
and analysis.
3.1.1.4. Volume
A physical unit used to store or distribute data products (e.g. a CD_ROM or 
DVD disk) which contain directories and files. The directories and files 
include documentation, software, calibration and geometry information as 
well as the actual science data. A volume is part of a volume set.  
3.1.1.5. Volume Set
A volume set consists of one or more data volumes containing a single data set 
or collection of related data sets. In certain cases, the volume set can 
consists of only one volume.

3.1.2. Data- and Volume Set Organization
The general concept for the MaRS, RSI and VeRa Data- and Volume Set Design is
shown in Figure 3.1-1.

3.2. Volume and Dataset Name Specification
  
3.2.1. Dataset
  
3.2.1.1. Dataset ID
The Data Set ID is a unique alphanumeric identifier for the MaRS, VeRa and RSI
data products. One data set corresponds to one physical data volume and both 
have the same four digit sequence number. See Table 3-1 for more information.

(1) It should be noted that the MaRS mission phase names used in the 
data_set_id do not correspond to the mission phase names as defined from ESA 
for Mars Express. However, since the radio science team tries has to archive 
data for Mars Express as well as for Venus Express and Rosetta, it was granted
the use of spacecraft-independent mission phase names which can be used for 
all three missions.

3.2.3. Volume
  
3.2.3.1. Volume ID
The Volume ID provides a unique identifier for a single MaRS, RSI or VeRa 
data volume, typically a physical CD-ROM or DVD. The volume ID is also 
called volume label by the various CD-ROM recording software packages. 
The Volume ID is formed using an instrument identifier of 3 characters, 
followed by an underscore character, followed by a 4 digit sequence number.

Table 3 - 5 : Volume ID 
Examples: 
  
MEXMRS_0001 
ROSRSI_0999 
VEXVRA_0508 
 

3.2.3.2. Volume Version ID
  
There can be several version of the same volume, if for example the archiving 
software changed during the archiving process or errors occurred during the 
initial production. This is indicated by the Volume Version ID, a string, 
which consists of a V for Version followed by a sequence number indicating 
the revision number.
  
VV.V 
 
      Acronym Description Example 
      VV.V Volume Version ID V1.0 

Table 3- 6: Volume Version Id 
 
If a volume is redone because of errors in the initial production or because 
of a change in the archiving software during the archiving process, the 
volume ID remains the same, and the Volume Version ID will be incremented. 


3.2.3.3. Volume Name
The volume name (formatted according to Table 3- 6 ) contains the name of the 
physical data volume (typically a CD-ROM or DVD) already identifiable by its 
VOLUME ID. Both the VOLUME ID and the VOLUME NAM E are printed on the CD-ROM 
or DVD labe l (see Figure 3- 2 ).

3.2.4.2. Volume Set Name
The Volume Set Name provides the full, formal name of a group of data volumes 
containing a data set or a collection of related data sets. Volume set names 
shall be at most 60 characters in length and must be in upper case. Volume 
sets are considered as a single orderable entity. In certain cases, the 
volume set name can be the same as the volume name, such as when the volume 

set consists of only one volume.

Table 4 - 1 : Data file naming convention 



5. Raw Tracking data Files (Level 1a)
All incoming data files will be renamed and all processed data files will be 
named after the file naming convention format defined in section 4.1 . The 
original file name of the incoming tracking data files will be stored in the 
according label file as original_product_id. 
  
5.1. Deep Space Network tracking data
5.1.1. File names of incoming level 1a DSN raw data files
  
The file names of the incoming Deep Space Network (DSN) tracking data files 
level 1a are not specified: 
  
      Abbreviation description 
      ODF Closed-loop ODF level 1a file 
      TNF Closed-loop Tracking Navigation File (TNF) Level 1a 
      RSR Open-loop RSR level 1a file 

  
  
5.1.2. File formats of incoming Level 1a DSN raw data files 
  
5.1.2.1. ODF Level 1a
  
The structure of binary ODF is described in the NASA document 
  
820-13, Rev B; TRK-2-18 ODF Orbit data File 
  
and in the IGM documents 
  
MEX-MRS-IGM-DS-3037 
DSN ODF (Orbit Data File) Processing Software: 
Level 1a to Level 1b 
Software Design Specifications 

5.1.2.2. RSR Level 1a
  
The RSR is a computer controlled open loop receiver that digitally records a 
spacecraft signal through the use of an analog to digital converter (ADC) and 
up to four digital filter sub-channels. The digital samples from each 
sub-channel are stored to disk at regular intervals in real time. In near 
real time the records are partitioned and formatted into a sequence of RSR 
SFDUs which are transmitted to JPLs Advanced Multi-Mission Operations System 
(AMMOS ). Included in each RSR SFDU is the ancillary data necessary to 
reconstruct the signal represented by the recorded data samples in that SFDU.
The structure of RSRs is described in the NASA document 
  
820-13, 0159 -Science 
Radio Science Receiver 
Standard Formatted Data Unit (SFDU) 
  
And in the IGM documents 
  
ROS-RSI-IGM-MA-3113-RSR-Read-Program-Manual 
MEX-MRS-IGM-MA-3026 RSR-Read-Program-Manual 
  
  
The physical layout of the RSR SFDU is divided into five sections: the SFDU 
label, the header aggregation CHDO label, the primary header CHDO, the 
secondary header CHDO, and the data CHDO. The primary header CHDO and the 
secondary header CHDO together constitute the value field of the header 
aggregation CHDO; the header aggregation CHDO and the data CHDO together 
constitute the value field of the RSR SFDU. 
The length of the RSR SFDU (in 8-bit bytes) is designated as N in this module. 
In general, the length of all items in the RSR SFDU are fixed, except for the 
data CHDO. The length of the data CHDO is variable and is determined by the 
sample rate and sample size of the recorded data. The length of the data CHDO 
is designated as M in this module. In any case, the total length of the RSR 
SFDU is easily ascertained from the length attribute in the SFDU label 
(total SFDU length N = SFDU length attribute + 20). 


5.1.2.3. Incoming calibration files from the DSN
  
5.1.2.3.1. DSN meteorological calibration file
The file name and format of the DSN meteo calibration file is described in 
section 9.2.1

section 7.7. 
5.1.2.4.4. SPICE kernels
The file name and formats of the SPICE kernel files is described in 
section 11. 

5.1.2.5. RSR Level 1a Browse Data Plots 
  
In order to check data quality of RSR Level 1a open-loop data, Stanford 
University is producing a 4-panel plot. These plots are in the tbd file 
format. 
  
The source identifier tttt is set according to the relevant RSR receiver 
channel and subchannel (see Tabel 4.1), the data level lll=L1A and the 
data type identifier is sss=BRO for browse data.

5.2.1.1. IFMS Level 1a incoming raw data file s 
5.2.1.1.1. IFMS raw data file name format
  
The nominal length of a filename of the IFMS is 31 characters, and increases 
only in the case that more than 9999 sequence IDs are needed, or in the case
 of raw (uncorrected) ranging data (more information in the referenced 
document IFMS-to-OCC). In that case, the IFMS expands the sequence IDs
 length, or add a filename extension, as needed. Level 1a files will be
 renamed according to the file name format defined in section 4.1 .

The input files for the processing software are: 
  The ODF level 1a file 
  
  
6.1.1.2.1. ODF level 1a file
The original ODF files have file names and formats according to section 5.1.1 
and 5.1.2. 
 

6.1.1.3. Output Level 1b products 
  
6.1.1.3.1. File name formats
A new file name is created and is formatted according to section 4.1 with the 
data archiving level set to lll = L1A. It replaces the original file name 
which is stored in the accompanying label file. The extension is set to 
eee = TAB. A DSN ODF file contains usually data covering several days and 
from different ground stations. Therefore, a general apointement to a 
specific ground station cannot be done and gg=00. 
The processed data file names of level 1b are formatted according section 4.1 
with the archiving level set to lll = L1b and eee = TAB.
The sequence number qq is not used for all DSN file types of level 1a and 
level 1b and is set qq = 00. 
  For the Doppler data sss = DPS or DPX 
  For the range data sss = RNS or RNX 
  For the uplink frequency ramp rate data sss = RMP 
  For the modified meteorological file sss = MET

      5 Distance 
        Propagation experiments: approximate value of the closest approach of 
        a downlink geometric ray path to the center of the reference body 
        (Sun, planet, minor object). When two-way, the value is approximate

      6 Transmit frequency ramp reference time 
        UTC in ISO format 
        The time (t0) at which the transmitted frequency would have been 
        using the coefficients f 0 (column 7) and df (column 8). At any time 
        within the interval when those coefficients are valid, the transmitted
        frequency f_t may be calculated from 
          f_t =f_0 + df x (t-t_0) 
        For DSN two-way measurements: 
        f_t is the uplink frequency of the ground transmitter; the f_t photon 
        will reach the receiver one RTLT later. 
        For DSN one-way measurements : 
        f_t is the downlink frequency of the spacecraft transmitter; the f_t 
        photon will reach the receiver OWLT later. In both cases, f_0 and df 
        may change; but f_t is always continuous, and changes in the 
        coefficients occur only on integer seconds. 
        For IFMS measurements: 
        f_t = f_0 
        because df=0.

      5 Distance 
        Propagation experiments: approximate value of the closest approach of
        a downlink geometric ray path to the center of the reference body 
        (Sun, planet, minor object). When two-way, the value is approximate

      6 Transmit frequency ramp reference time 
        UTC in ISO format 
        The time (t0) at which the transmitted frequency would have been f_0
        using the coefficients f_0 (column 7) and df (column 8). At any time
        t within the interval when those coefficients are valid, the 
        transmitted frequency f_t may be calculated from 
        f_t = f_0 +dt x (t-t_0) 
        For DSN two-way measurements: 
        f_t is the uplink frequency of the ground transmitter; the f_t photon
        will reach the receiver one RTLT later. 
        For DSN one-way measurements : 
        f_t is the downlink frequency of the spacecraft transmitter; the f_t 
        photon will reach the receiver OWLT later. In both cases, f 0 and df
        may change; but f_t is always continuous, and changes in the
        coefficients occur only on integer seconds. 
        For IFMS measurements: 
        f_t = f_0 
        because df=0.

6.2.2. Closed-loop IFMS level 2 products 
  
6.2.2.1. Specifications document
The IFMS level 2 processing is specified in the documents 
  
MEX-MRS-IGM-DS-3035 
IFMS Doppler Processing Software: Level 1a to Level 2 
  
MEX-MRS-IGM-DS-3036 
IFMS Ranging Processing Software: Level 1a to Level 2 
  
6.2.2.2. Input files
The input files are: 
  The IFMS level 1a files (D1S,D1X, D2S,D2X, RGX,RGS) 
  The orbit reconstructed file (RWT or RON) 
  The range calibration file (RCX or RCS) 
  Meteorological file 
  AGC file 
  Klobuchar coefficients for Earth ionosphere cali bration 
  Spacecraft orbit SPICE kernels 
  
  
6.2.2.2.1. The orbit reconstructed file RTW or RON
The content and format of the predict file is described in section 8. 
 
6.2.2.2.2. The range calibration file RCX or RCS 
  
The content and format of the range calibration file RCX and RCS is described
in section 9 
  
6.2.2.3. Output IFMS Level 2 products 
  
There may be several Doppler 1 X-Band files in level 1a which will 
be merged on level 2. The same is true for all other Doppler file type and 
Ranging X and S-Band files. Only files with continous sequenced numbers (the
file names are the same only the sequence number varies for these files) are
merged together. Otherwise a new 
Level 02 data file is created (merging data files with a new sequence of
files). 

The level 2 source_product_id however gives the RAW IFMS file names since the 
raw files are used for processing. But the content of the IFMS raw files are 
identical to the corresponding level 1a IFMS files in one data set, only the 
file name is different. And the source_product_id of the level 1a files gives
the original raw IFMS files. In addition the level 1A files have almost the
same file name as the corresponding level 2 files. The corresponding 
level 1A files can be found in 
DATA/L1A/CLOSED_LOOP/IFMS/DP1 for Doppler 1 files 
DATA/L1A/CLOSED_LOOP/IFMS/DP2 for Doppler 2 files 
DATA/L1A/CLOSED_LOOP/IFMS/RNG for Ranging files 
  
M32ICL1L02_D1X_040931103_00.TAB is a level 2 Doppler 1 X-Band file 
  
in M32ICL1L02_D1X_040931103_00.LBL the following SOURCE_PRODUCT_ID is given: 
  
SOURCE_PRODUCT_ID = {"NN11_MEX1_2004_093_OP_D1_110358_0000", 
"NN11_MEX1_2004_093_OP_D1_110358_0001", 
"NN11_MEX1_2004_093_OP_D1_110358_0002"} 
  
which are the raw IFMS files. The corresponding Level 1A files can be found
in DATA/L1A/CLOSED_LOOP/IFMS/DP1 
  
Their names are: 
M32ICL1L1A_D1X_040931103_00.RAW 
M32ICL1L1A_D1X_040931103_01.RAW 
M32ICL1L1A_D1X_040931103_02.RAW 
  
and the corresponding label files give the source_product_id as: 
in the M32ICL1L1A_D1X_040931103_00.LBL file the source_product_id is given as:
SOURCE_PRODUCT_ID = "NN11_MEX1_2004_093_OP_D1_110358_0000" 
in the M32ICL1L1A_D1X_040931103_01.LBL file the source_product_id is given as:
SOURCE_PRODUCT_ID = "NN11_MEX1_2004_093_OP_D1_110358_0001" 
in the M32ICL1L1A_D1X_040931103_02.LBL file the source_product_id is given as:
SOURCE_PRODUCT_ID = "NN11_MEX1_2004_093_OP_D1_110358_0002" 
  
Note that in this example the three three level 1A files were merged to one 
level 2 files. 
The file names of the level 1a files are almost identical to the level 2
file name with three differences: 
- L1A instead of L02 in the file name which tells the user that these are
 level 1A and level 2 files. 
- The two digit-sequence number at the end of the file can be different. 
- The level 1A files have file extension .RAW whereas level 2 files have file 
extension .TAB 

Table 6 - 14 : Example of the connection of Level 2 and 1a files. 



6.2.2.3.1. File name formats
The file names of the IFMS output level 2 files are formatted according to 
section 4.1 with the archiving level identifier set to lll = L02 and the file 
source identifier set to tttt = ICL1 or ICL2 or ICL3 for the IFMS 1, 2 or 3, 
respectively. The file type is set to sss = D1X or D2X for X-band Doppler or
 sss = D1S or D2S for S-band Doppler, respectively, or sss = RGX or RGS for 
calibrated X-band or S-band ranging files, respectively.

6.2.2.3.2. Log-Files
Additionally a log-file is produced which contains information about the
 Level 2 processing of Doppler or Ranging data. These log-files are stored in 
EXTRAS/ANCILLARY/MRS/LOGFILES. The name of the files are the same like the
 Level 2 data files except for the sequence number qq and the extension. The
 sequence number is started with 00 and will be incremented by every new
 processing of the data. The extensions will be .LOG

9.1.3. IFMS Doppler Calibration Files
  
The IFMS doppler calibration file is taken before or after the NNO tracking
 pass at the same time as the IFMS ranging calibration file. 
  
9.1.3.1. File name
The doppler calibration file name is formatted according to section 4.1 by 
setting the archiving level to lll = L1B , the file type to sss = C1X or C2X
 or C1S or C2S, the file type is set to tltt = ICL1 or ICL2, depending on the 
uplinking IFMS and the ground station is gg = 32.

9.1.4. IFMS meteorological calibration
The meteorological file is the Level 1b IFMS output and describes the 
temperature, atmospheric pressure and humidity at the ground station site. The 
file is accompagnied by the IFMS configuration file *.CFG (see Appendix 12.1
 for content). Since the meteorological information is stored independently
 from doppler and ranging measurements, these files usually do not start and
 stop at the same time as a Doppler or range data file. That means that
 sometimes the meteorological data applicable for a Doppler or range
 data file has to be extracted from two files. 

9.1.4.1. File name format
The file name of the meteorological file is formatted according to section 4.1 
by setting the archiving level to lll = L1B , the file type to sss = MET, the 
file type is set to tltt = ICL1 or ICL2, depending on the uplinking IFMS and
 the ground station is gg = 32.

9.2.5	Surface Reflection Filer Files

Surface Reflection Filter files (SRF) contain power spectra derived from noise measurements when the radio system was stable and there were no spacecraft signals in the passband.  SRF's were derived separately for each receiver channel; but the fact that the spectral characteristics of each receiver depended almost entirely on digital signal processing meant that there was little practical difference among channels when sampling rates (output bandwidths) were the same and the SRF's were interchangeable.

9.2.5.1	File name format

GNC's are ASCII files having names of the form

SRF's are ASCII PDS SPECTRUM objects with attached labels.
           
9.2.6	Bistatic Radar calibration log files

Bistatic radar calibration log files (BCL) contain system temperature 
calibration results. For each receiver channel the table includes the 
best estimate of system temperature with the antenna pointed to zenith 
(either pre- or post-cal, or a combination of both), the associated noise 
diode temperature, and the system temperature at the mid-point of the 
bistatic (surface) observation.  In general there is one set of four rows 
for each experiment - one for each receiver channel 
(X-band and S-band, right- and left-circular polarization). 
The table is cumulative, growing by four rows for each new observation. 
The Bistatic Radar Calibration files are produced by the Stanford 
University Element (SUE) under the direction of R.A. Simpson.

9.2.6.1	File name format
BCLs are ASCII files having names of the form

rggSUE0L1A_BCL_yydddhhmm_qq.TAB
  
Since these files are cumulative the first file from Stanford gets 
after renaming the sequence number _00 and when an updated BCL - 
usually after a new bistatic radar measurement - is received the new file
 will get the same file name as the first file but the sequence number is
 increased by one and so on. Utimately only the files with the higest 
version numbers will be archived since these contain the latest 
information. The extension is set to eee = TAB

9.2.6.2	File format

BCLSs are ASCII tabels with dettached labels.

        SL: S-Band; left circula
3 Zenith time in UTC; 
        ZENITH_TIME is usually an average time for the interval over 
        which the values were obtained, typically a few tens of minutes. 
        In some cases pre-calibration and post-calibration values were 
        both used, in which case the interval covers several hours.

12 Time standards and Formats
12.1. Time Standards
MaRS, RSI and VeRa data products makes use of different Time and Reference 
system. For our data processing and archiving the most important Time Systems 
are: 
  Coordinated Universal Time (UTC) 
  Ephemeris Time (ET) 
  
The scientific success of a Radio Science Experiment depends critically on a 
common understanding about the conventions for the reference and time systems. 
The following sections give an overview of the time standards necessary to 
understand the above mentioned Time systems and to convert to other common
 Time Systems. It should be noted that radio science data are generated and
 recorded at ground stations. Thus the times given in the data and label
 files are ground station and not onboard time. 
  
12.1.1. Coordinated Universal Time (UTC)
  
Coordinated Universal Time (UTC) is obtained from atomic clocks running at the
same rate as TT (see section 12.1.3.3 ) or TAI (see section 12.1.3.2 ). The
 UTC time scale is always within 0.7 seconds of UT1 (see section 12.1.3.5 ).
 By the use of leap seconds, care is taken to ensure that this difference is
 never exceeded. However, because of the introduction of the leap seconds it
 becomes clear that this time scale is not steady. 
The International Earth Rotation Service (IERS) can add leap seconds and is 
normally doing this at the end of June or December of each year if necessary.
The actual UTC can only be determined for a previous point in time but 
predictions for the future are published by the IERS. This fact should be
 noted when future missions are planned on the base of the UTC time standard. 
UTC can be obtained by the difference of the predicted value DUT1 or the past
value D UT between UT1 and UTC published in the IERS Bulletin A 
(http://maia.usno.navy.mil/) which contains previous leap seconds and 
predictions : 
 or UTC = UT - D UT 
  
This relation is needed to obtain UT1 (UT) from UTC. 


  
12.1.2. Dynamical Time Scale T eph for the JPL DE 405 Ephemeris
  
In a general relativistic framework, time is not an absolute quantity but 
depends on the location and motion of a clock. Therefor unlike UTC T eph is
 not based on the rotation of the earth around its axis. T eph refers to the
 center of mass of the solar system and is the independent variable of
 barycentric planetary ephemerides. It should be noted that during the
 years 1984 2003 the time scale of ephemerides referred to the barycenter of
 the solar system was the relativistic time scale Barycentric Dynamic Time TDB
 (see section 12.1.3.1 ). From 2004 onwards this time scale for the
 JPL DE 405 ephemeris will be replaced by T eph. For practical purposes the
 length of the ephemeris second can be taken as equal to the length of the
 TDB second. T eph is approximately equal to TDB, but not exactly. On the
 other hand, T eph is mathematically and physically equivalent to the
 newly-defined TCB (see section 12.1.3.7 ), differing from it by only an
 offset and a constant rate. Within the accuracy required by MaRS, RSI and
 VeRa we use: T eph ~ TDB. T eph is then defined as seconds past J2000, with
 J2000 being 12 h 1 January TDB. 

12.1.3. Other Time Standards
  
12.1.3.1. Barycentric Dynamic Time (TDB)
  
Since the differences compared to TT are fairly small, the corrections can be 
determined by the following approximation : 
 
TDB = TT + 0.001658 sec x sin g + 0.000014 sec x sin (2g)
with g being the mean anomaly of the Earth in its orbit given by 
g=357.53 + 0.95856003 x (JD(UT1)-2451545.0) [deg] 

12.1.3.2. International Atomic Time (TAI)
TAI provides the practical realization of a uniform time scale based on atomic 
clocks. This time is measured at the surface of the Earth. Since this time
 scale is a steady one, it differs from UTC by an integral number of leap
 seconds introduced up the current point in time: 
TAI = UTC + LS 
where LS is the number of leap seconds. The unit of TAI is the SI second.

12.1.3.3.Terrestrial Dynamic Time (TT)
  
Terrestial Time (TT) ? formerly Terrestrial Dynamical Time (TDT) - is to be 
understood as time measured on the geoid. It has conceptionally a uniform time 
scale. TT is the independent variable of geocentric ephemerides. TT replaced 
Ephemeris Time (ET) in 1984. The difference between TT and the atomic time
 scale (TAI) is a constant value of 32.184 seconds: 
 
TT=TAI+32.184 sec 
  
One therefore obtains also the relationship: 
 
UTC=TT-32.184 sec - LS 
TT does not take into account relativistic corrections. It is used as an 
independent argument of geocentric ephemeris. 
  
12.1.3.4. GMT (UT)
  
Time is traditionally measured in days of 86400 SI seconds. Each day has 24 
hours counted from 0 h at midnight . The motion of the real sun was replaced
 by the concept of a fictitious mean sun that moves uniformly in right
 ascension defining the Greenwich Mean Time (GMT) or Universal Time (UT).
 Greenwich Mean Sidereal Time (GMST), however, is the Greenwich hour angle
 of the vernal equinox, i. e. it denotes the angle between mean vernal
 equinox of date and the Greenwich meridian. 
The mean vernal equinox is based on a reference system which takes into
 account the secular effects, i.e. the precession of the Earth?s equator but
 not periodic effects such as the nutation of the Earth?s axis. 
In terms of SI seconds, the length of a sidereal day (i. e. the Earths spin
period) amounts 23 h 56 m 4 s.091 ? 0 s.005 (corresponding to a factor 
1/1.00273790935) making it about four minutes shorter than a 24 h solar day. 
Hence, sidereal time and mean solar time have different rates. 


12.1.3.5. Universal Time (UT1)
  
Universal Time UT1 is the presently adopted realization of a mean solar time 
scale (constant average length of a solar day of 24 hours) with UT1 = UT. As
 a result, the length of one second of UT1 is not constant because of the
 apparent motion of the sun and the rotation of the Earth. UT1 is therefore
 defined as a function of sidereal time. 
For any particular day, 0 h UT1 is defined as the instant at which Greenwich 
Mean Sidereal Time (GMST) has the value: 
GMST(0h UT1) = 24110.54841 sec + 8640184.812866 sec x T_0 + 0.093104 x 
T_0exp(2)-0.0000062 sec x T_0exp(3)
For an arbitrary time of the day, the expression may be generalized to obtain
the Greenwich hour angle GHA by multiplying this time with the factor 
1.00273790935, adding this result to GMST and convert it into degrees (if so 
desired) 
GMST(UT1) = 24110.54841 sec + 8640184.812866 sec x T_0 + 1.00273790935 UT1 + 
0.093104 sec x Texp(2) - 0.0000062 sec x Texp(3) 
where T is the time in Julian centuries since the 1st of January 2000 , 12 h, 
i.e. 2000 Jan. 1.5 : 
 
T = (JD(UT1)-2451545)/36525 
 
and JD is the Julian Date. 
  
Ecliptic and Earth equator at 2000 Jan 1.5 define the J2000 system. 
  

The most useful relation for computer software is one that uses only JD (UT1):
GMST(degree) = 280.46061837 + 360.98564736629 x (JD-2451545.0) + 0.000387933 
Texp(2) - Texp(3) /38710000
 
The difference between UT1 and TT or TAI ( atomic clock time, to be explained 
below) can only be determined retrospectively. This difference is announced by 
the International Earth Rotation Service (IERS) and is handled in practice by 
the implementation of leap seconds (maximum of two in one year). 
The above formulae contain implicitly the Earth?s mean angular rotation
 omega in degrees per second [3.15]. 
Omega (rad/sec)=(1.002737909350795+5.9006 x 10E-11 T -5.9 x 10E-15 Texp(2))
 x 2 PI/86400 sec 
  
12.1.3.6. Geocentric Coordinate Time (TCG)
  
Geocentric Coordinate Time TCG represents the time coordinate of a four 
dimensional reference system and differs from TT by a constant scale factor 
yielding the relation 
 
TCG = TT + L_G (JD-2443144.5) x 86400 sec 
L_G = 6.9692903 x 10E-10 
  
For practical reasons this equation can also be put into the following
 relation : 
TCG = TT + 2.2 s/cy x (year-1977.0) 
  
cy = century 
  
  
12.1.3.7. Barycentric Coordinate Time (TCB)
  
The Barycentric Coordinate Time TCB has been introduced to describe the motion 
of solar system objects in a non rotating relativistic frame centered at the 
solar system barycenter. TCB and TCG exhibit a rate difference which depends
 on the gravitational potential of the Sun at the mean Earth-Sun distance
 1 AU and the Earth?s orbital velocity. The accumulated TCB-TT time
 difference amounts to roughly 11 s around epoch J2000. 
TCB = TCG + L_C (JD-2443144.5) x 86400 sec +P 
(Mc Carthy 1996) and 
P approximately +0.0016568 sec x sin(35999.37 degree T + 357.5 degree) 
+0.0000224 sec x sin(32964.5 degree T + 246 degree)
+0.0000138 sec x sin(71998.7 degree T + 355 degree) + 0.0000048 sec x
 sin(3034.9 degree T +25 degree) + 
+0.0000047 x sin (34777.3 degree T +230 degree) 
T=(JD-2451545.0)/36525
  
L_c = 1.4808268457 x 10E-8 
  
The largest contribution is given by the first term. When neglecting the other 
terms we can approximate P by: 
  
P = 0.001658 s sin(g) + 0.000014 s sin(2g) 
  
12.1.3.8. Julian Date (JD)
  
In astronomical computations, a continuous day count is used which avoids the 
usage of a calendar. The Julian Date (JD) is the number of days since noon 
January 1, 4712 BC including fractions of the day. 
  
12.1.3.9. Modified Julian Date (MJD)
  
Since the JD has become such a large number, the Modified Julian Date was 
introduced for convenience. JD was reset at November 17 th 1858 which leads to 
the following equation : 
MJD=JD-2400000.5 days 
 
Note that the count for MJD starts at midnight . 
  
12.2. Time formats
12.2.1. ISO Time Format
  
In our data and label files we use UTC time to measure the time the data were 
recorded at the ground station in the PDS compliant ISO/DIS 8601 standard
 format CCYY-MM-DDTHH:MM:SS.sss. (Example: 2004-06-21T025208.000 corresponds
 to the date 21.6.2004 and the time of day 2:52:08.000). 


12.2.2. Time in Fractions of Days of Year 
  
This is the UTC time in the format fraction of days of year starting with the 
first day of year the data was recorded at 00:00.000 UTC. (Example: 
2003-07-01T18:03:02.000 in ISO format corresponds to 182.752106 in fraction of 
days since the 1 st July was the 182th day of the year 2003.) This format is 
only used in the data files. 
  
12.2.3. Ephemeris Time Format
  
Ephemeris time is given in seconds starting with the 1 st January 2000 at 
12:00:00.000 TBD (see also section 12.1.2 ).
