MEX-M-MRS-1-2-3-NEV-0002

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 20030701T18:03:02.000 to 20030702T00:09:31.000. 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 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（Mars Express，简称MEX）无线电科学（MaRS）数据存档是对火星任务期间收集的原始数据及部分处理数据的按时间顺序排列的集合。有关提议的调查信息，请参阅MaRS用户手册《MARSUSERMANUAL2004》，位于MaRS文档夹/MRS_DOC中。本测量数据为 Commissioning 测量，覆盖时间范围为20030701T18:03:02.000至20030702T00:09:31.000。此数据集在MEX任务近地验证阶段（NEV）发射后不久收集。当日未进行特定测量，但进行了配置测试。测试在NEV、CR1以及MCO任务阶段的部分时间进行。在NEV期间，执行了多项 Commissioning 测量，旨在测试搭载航天器的无线电应答器和振荡器，以及地面站（主要是新诺西亚（NNO）的新ESA地面站）的设备。更多信息请参阅INST.CAT或MaRS用户手册《MARSUSERMANUAL2004》。所执行测量的概述：在第180天（20030629），在新诺西亚进行了所谓的TWODX配置的跟踪。即，在IFMS 1和X频段进行X波段上行链路，同时进行S频段相干和同步下行链路。在整个过程中进行了多普勒记录。UTC 18:00：传输调制器开启，距离测量开启；UTC 19:45：传输调制器关闭，距离测量关闭；UTC 23:45：传输调制器开启，距离测量开启；UTC 01:00：操作结束。数据采样率为每秒1次。在第182天（20030701），在新诺西亚进行了所谓的TWODX配置的跟踪。即，在IFMS 2和X频段进行X波段上行链路，同时进行S频段相干和同步下行链路。整个过程中进行了多普勒记录。UTC 18:00：传输调制器开启，距离测量开启；UTC 19:05：传输调制器关闭，距离测量关闭；UTC 23:05：传输调制器开启，距离测量开启；UTC 00:05：操作结束。数据采样率为每秒1次。在第183天（20030702），在新诺西亚进行了所谓的TWODS配置的跟踪。即，在IFMS 1和X频段进行S频段上行链路，同时进行S频段截断，请参阅实际数据以获取完整内容。[截断，请参阅实际数据以获取全文]
