MEX-M-MRS-1-2-3-NEV-0007

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 20030710T12:45:00 to 20030710T19:30:00. 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). For more information see INST.CAT or the MaRS User Manual MARSUSERMANUAL2004. Overview of perfomed measurements: DOY 180, 20030629: Tracking at New Norcia performed in the so called TWODX configuration. That is, XBand uplink at IFMS 1 and X and SBand coherent and simultanous downlink. Doppler recording was performed all the time. 18:00 UTC: TM ON, Ranging ON 19:45 UTC: TM OFF, Ranging OFF 23:45 UTC: TM ON, Ranging ON 01:00 UTC: End of operation Data sample rate was 1/sec. DOY 182, 20030701: Tracking at New Norcia performed in the so called TWODX configuration. That is, XBand uplink at IFMS 2 and X and SBand coherent and simultanous downlink. Doppler recording was performed all the time. 18:00 UTC: TM ON, Ranging ON 19:05 UTC: TM OFF, Ranging OFF 23:05 UTC: TM ON, Ranging ON 00:05 UTC: End of operation Data sample rate was 1/sec. DOY 183, 20030702: Tracking at New Norcia performed in the so called TWODS configuration. That is, SBand uplink at IFMS 1 and X and SBand coherent truncated!, Please see actual data for full [truncated!, Please see actual data for full text]

数据集概览：火星快车号（MEX）无线电科学（MaRS）数据档案是一个按时间顺序排列的原始及部分处理数据集合，这些数据是在火星快车号对火星任务期间收集的。关于拟议的调查信息，请参阅MaRS用户手册MARSUSERMANUAL2004，该手册位于MaRS文档/MRS_DOC文件夹中。本测量数据集涵盖了20030710T12:45:00至20030710T19:30:00的时间段。该数据集是在火星快车号近地验证阶段（NEV）发射后不久收集的。当日未进行特定的测量，但进行了配置测试。测试是在NEV、CR1及部分MCO任务阶段进行的。在NEV期间，执行了多项旨在测试飞船上的无线电应答器和振荡器，以及地面站（主要是新的欧洲航天局地面站New Norcia，NNO）的配置测试。更多信息请参阅INST.CAT或MaRS用户手册MARSUSERMANUAL2004。已执行测量概述：在第180天（20030629），在New Norcia执行了所谓的TWODX配置的跟踪任务。即，在IFMS 1处进行X波段上行链路，X和S波段进行相干且同时的下行链路。在整个过程中进行了多普勒记录。UTC时间18:00：传输模式开启，测距开启；UTC时间19:45：传输模式关闭，测距关闭；UTC时间23:45：传输模式开启，测距开启；UTC时间01:00：操作结束。数据采样率为每秒1次。在第182天（20030701），在New Norcia执行了所谓的TWODX配置的跟踪任务。即，在IFMS 2处进行X波段上行链路，X和S波段进行相干且同时的下行链路。在整个过程中进行了多普勒记录。UTC时间18:00：传输模式开启，测距开启；UTC时间19:05：传输模式关闭，测距关闭；UTC时间23:05：传输模式开启，测距开启；UTC时间00:05：操作结束。数据采样率为每秒1次。在第183天（20030702），在New Norcia执行了所谓的TWODS配置的跟踪任务。即，在IFMS 1处进行S波段上行链路，X和S波段进行相干截断！请参阅实际数据以获取完整信息[截断！请参阅实际数据以获取完整信息]。
