DOY Start BOT EOT End Facility User Activity Pass 092 2230 0130 0410 0510 DSS-43 MEX BISTATIC 0672 1. OVERVIEW: The purpose of this briefing message is to provide DSN operations with information regarding equipment configurations and directions to ensure Mars Express Bi-Static Radar objectives as stated below are met. The objective of the Mars Bistatic Radar (BSR) experiment is to collect science data, which may reveal information about the physical structures and electrical properties of the Martian surface. The experiment employs the MEX spacecraft transmitter and DSN 70-m aperture antennas to receive the weak RF signals and DSN Radio Science Receivers (RSRs) to simultaneously process and record four RF signals. At a predetermined time during the pass, the spacecraft is slewed toward Mars so that its transmitted S-band and X-band RCP signals illuminate the planet's surface. As these RCP signals bounce off the surface, part of the signals change polarization to Left Circular Polarization (LCP) effectively creating four signals; 1) S-band RCP, 2) S-band LCP, 3) X-band RCP and 4) X-band LCP. To meet Bistatic Radar experiment objectives DSN operations must perform four precise measurements and calibration procedures in accordance with MEX NOP 871-041, Rev.A section-11, PCN-1. 2. SUPPORT DOCUMENTATION: a. Mars Express NOP 871-049-041, Rev. A, PCN-1 b. This briefing message c. Sequence of Events 3. SUPPORT REQUIREMENTS: All support requirements and operations procedures given below are in accordance with Mars Express NOP 871-049-041, Rev. A, PCN-1 Section-11. a. DTTs (Downlink Tracking and Telemetry) Receivers: * One DTT shall be configured with table 7041HRX to support X-band telemetry and to control the 12.5k noise diode on/off at predetermined times during pre-pass calibrations, real-time BSR activities and post calibrations activities. * A second DTT shall be configured with table 7041HRXS to support S-band carrier lock only and to control the 12.5 k noise diode on/off at predetermined times during pre-pass calibrations, real-time BSR activities and post calibrations activities. b. Ranging: There is no uplink or Range requirement c. Command: There is no uplink or command requirement d. Radio Science Receivers (RSRS): NOTE: For remote operations the FSPR must not be assigned to the DSS link. The RSRs are controlled and configured remotely by the Radio Science group located at JPL. The RSR operator will configure four radio science receivers to simultaneously receive and record S-band and X-band RCP and LPC polarized signals. The RSR equipment requires both S-band and X-band 1-way and 2-way downlink predicts. The actual RSR resources configured for support will depend on availability. 1. R1B IFS 43_S_RCP 2. R2A IFS 43_S_LCP 3. R1A IFS 43_X_RCP 4. R2B IFS 43_X_LCP 4. NOCT: a. Transmit X-band up/down, and X-up/S-band down predicts to the station 5. GCF: a. Voice: DSS /ROC MOPS/AMMOS/MEX MOC/ RS b. Data: DSS /AMMOS/ MEX MOC 6. Spacecraft Configuration: The spacecraft is configured to simultaneously transmit X/S-band RCP 7. Pre-Calibration Procedures and Configuration a. Bistatic Radar pre-calibration procedures are performed during the station allocated 2.5 hr setup time. b. Link Controller configure the 70m-antenna microwave subsystem as follows: 1. Dichroic plate in place (extended) 2. Diplexer must be configured to receive S-RCP and input to LNA-1 3. Non-Diplexer (low noise) must be configured to receive S-LCP and input to LNA-2 4. X-band LNA-1 must be configured to receive X-RCP 5. X-band LNA-2 must be configured to receive X-LCP 6. Antenna pointing to zenith 7. Use current SEMOD configuration for X-up, S/X down c. Pre-calibration requires configuring the 70m-antenna microwave subsystem so that each receiving downlink channel (S-RCP, S-LCP, X-RCP, X-LCP) can be cycled in sequence through the four configurations listed here: 1. Receiving channel into ambient load with noise diode off 2. Receiving channel into ambient load with noise diode on 3. Receiving channel into sky (zenith) with noise diode on 4. Receiving channel into sky (zenith) with noise diode off d. Link Controller configure the DSS equipment using the operator directives given below and in the sequence shown in steps-1 through steps-17.

The following might lead to minor improvements: 7. d. Suggest adding at end of first paragrapgh "The times shown are to illustrate event chronology and event duration." This sentence appears in sections 8 and 10; but it would also be useful in 7, which most readers will see first. 10. Missing close-parenthesis at end of first sentence. 10. Step-1: Could use a "DC01 SET SC BND=X" in the DTT 01 setup. 10. Step-4: "DC02 SET SNT MFQ=ON" appears here but nowhere else in the entire procedure. Should we add a pair of them, at least in the pre-cal? 10. Should you renumber this to be Section 9? I haven't found 9 anywhere; the BM jumps from 8 to 10. Our experiment on 10 April also uses DSS 43; we can probably use this BM again. The experiment on 24 April is at DSS 14; we should think about what modifications are needed to port the procedure to the new antenna. Given our experience at Goldstone last year and the fact the DSS 43 procedure/BM appears very similar, I'm optimistic we can pull off the Goldstone experiment without needing a test beforehand. But we might want to discuss this with more knowledgeable people.

I shall make corrections to the briefing message for the April 10th DSS-43 support. I have yet to convince management of my need for PDF software... I shall prepare a briefing message for Goldstone, following the DSS-43 briefing message format. 10. Step-1: Could use a "DC01 SET SC BND=X" in the DTT 01 setup. During DTT setup the operator loads configuration table "7041HRX" which configures the downlink for X-band, and is good until the link is reconfigued. 10. Step-4: "DC02 SET SNT MFQ=ON" appears here but nowhere else in the entire procedure. Should we add a pair of them, at least in the pre-cal? During the BSR support with DSS-43 the link operator assisting me stated that operator directive "DC02 SET SNT MFQ=ON" is not really needed; I need to decide either to remove of delete it - I shall follow up on this.

But 02:15:00 would be a reasonable placeholder for the beginning of the mini-cal. Your second xx:xx:xx is for the "end" of the mini-cal activity. It would be more useful to show the time at which we BEGIN the second round of mini-cals (Steps 1-5). For that I would use 03:35:00 as a placeholoder; in which case the "end" of the mini-cal activity would be around 03:50. But this all depends on how smoothly the steps are executed. Note that both of my times (03:35 and 03:50) are AFTER your 03:34:15. Note that lines 031 and 032 in the original SOE are spurious; DSS 43 will not "lose" the signal because it's not likely there will be anything there in the first place. Also, your inserted lines at 02:33:05 suggesting that DSS 43 will "acquire" the signal are probably not helpful; if there is a signal, it will be so weak that station personnel will not be able to lock on to it. One line you might consider adding would be to note that the maximum echo from the surface is expected at 03:04:18 (give or take 10 minutes). But this will also be very weak. >I need to delivery this revised SOE to the DSN as soon as possible. Good enough?

I'm still getting 34750 from the query. Sometimes it takes a while for data to percolate through; I'll try again tomorrow. If no better, then we can just let it go. The RSR1B4 recording was for backup; we have the echo in RSR1B3 and (if we need to locate the carrier) we may be able to use RSR2B4 for frequency calibration. Thanks for the second try.

Decode it with "munpack" or any other MIME reading software. Mpack/munpack is available via anonymous FTP in ftp.andrew.cmu.edu:pub/mpack/ --- Martin: Here are preliminary results from the bistatic radar experiment on 3 April. The raw data were "equalized" - to remove ripples in the spectrum from the RSR filters. The correction is not perfect, but it helps. We then determine the system temperature of each receiver at the center time of the bistatic interval - which is usually taken to be 20 minutes total. This is where the pre-calibration, mini-calibrations during the experiment, and post-calibrations come in. These calibration data look very good when compared with the data we collected in February; the system temperatures at zenith and the noise diode values are very similar. The system temperature during the BSR observations is more variable, however, possibly reflecting poorer weather conditions at DSS 43 and a lower elevation angle. Overall, I have no reason to doubt the validity of our calibrations in spite of these less than ideal conditions. The "equalized" RSR samples are then scaled to give exactly the measured Tsys values when the data are converted to power spectra. When the (now flat) noise baseline is removed, the remaining power is attributed to the surface echo (except for a residual S-band carrier which can be seen on the left and is easily omitted from the echo power calculation). We compute 4 power spectra for each receiver; each is an average of 5 minutes of data. You can see the echo rise in the first two, then fade in the second two. The table below shows the echo power in zeptowatts (10**-21 watts) for each receiver and each time interval. The fifth column (rightmost) gives the sum over the total 20 minutes. There are also lines showing the ratio of RCP to LCP for both X- and S-band. Our target for these observations was (50.97S, 70.64W); this is in cratered terrain west-southwest of Argyre. The angle of incidence at the specular point should have been 51.11 degrees. In fact, a range of latitudes, longitudes, and incidence angles contributed to the echo; so I wouldn't worry about any figures to the right of the decimal points. At 51.11 deg, the X-band cumulative ratio 0.360 corresponds to a dielectric constant of 3.19. The S-band ratio of 0.320 corresponds to a dielectric constant of 3.52. As with the experiment in February, we see a larger dielectric constant at S-band, which is consistent with its deeper probing of the soil. But these numbers are significantly larger than the values ~2 that we found in February when the nominal specular point was actually in the mountainous rim of Argyre (55.95S,324.75E) and at an incidence angle of about 61.19 deg, except that the HGA was mispointed. - Power in Surface Echo Summed over Each Spectrum and All Spectra - SPECTRUM_1 SPECTRUM_2 SPECTRUM_3 SPECTRUM_4 SUM_SPECTRA ---------- ---------- ---------- ---------- ----------- XR 26.398 86.229 88.910 17.997 219.533 XL 67.983 228.299 243.177 70.771 610.230 XR/XL 0.388 0.378 0.366 0.254 0.360 ---------- ---------- ---------- ---------- ----------- SR 0.411 4.031 4.354 3.922 12.718 SL 5.361 14.782 12.667 6.996 39.805 SR/SL 0.077 0.273 0.344 0.561 0.320 - The attachment includes the Level 2 (SPC) product and its label and summary plots showing the four power spectra. The plots were derived directly from the SPC file after removing the first four rows (header table). The first (bottom) trace is black, the last (top) is green. The cross-spectra are also included in the SPC file; I glanced at some cross-spectra at an intermediate stage but have not included any of those results as plots here. I have some intermediate JPG files, which I could send if you thought they might be useful in the SOWT. A "waterfall" plot of the X-LCP RSR output in 60-second steps may be the most interesting; but the individual traces are noisy and the inexperienced eye may have trouble seeing the echo against the background. I'll include a copy in the attachment; let me know if you want more choices. Dick PS: The attachment is actually a ZIP file.
