MEX-M-MRS-1-2-3-NEV-0005

Data Set Overview The Mars Express (MEX) Radio Science (MaRS) Data Archive is a timeordered collection of raw and partially processed data collected during the MEX Mission to Mars. For more information on the investigations proposed see the MaRS User Manual MARSUSERMANUAL2004 in the MaRS DOCUMENT/MRS_DOC folder. This is a Commissioning measurement covering the time 20030706T14:18:30 to 20030706T22:09:00. Parallel tracking pass at Deep Space Network (DSN) station DSS 43 (70 meter station also uplinking) and New Norcia (only listening). Space craft was in ONED mode that is uplink was switched off during operation. But there was Xand SBand downlink. Doppler recording was performed all the time. Data recording at DSN: TNF (closed loop) and RSR (open loop) data. Data recording at NNO: Doppler, Meteo, Auto Gain Control and Ranging files at a sample rate of 1/sec. 15:00 UTC: Space craft is in TWODX configuration, TM ON, Ranging ON 16:00 UTC: Begin of ONED activity, Ranging off, TM ON (??) 17:05 UTC: TM OFF and Ranging OFF 19:08 UTC: TM ON 20:07 UTC: XBand Uplink up. End of ONED, begin of normal TWODX. Ranging ON 21:08 UTC: End of activity Twoway Ranging and Doppler recordings were done before and after the ONED activity. This data set was collected during the MEX Mission Near Earth Verification Phase (NEV) shortly after launch. No specific measurement was done on this day but the configuration was tested. Testing was done during the NEV, CR1 and partly MCO Mission phase. During NEV several comissioning measurements were performed which had to purpose to test the radio transponders and oscillator aboard the space craft as well as the equipment at the ground stations mainly at the new ESA ground station New Norcia (NNO).
