MEX-X-MRS-1-2-3-EXT7-4037

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 see the MaRS User Manual MARSUSERMANUAL2004 in the MaRS DOCUMENT/MRS_DOC folder. This is a Solar Conjunction measurement covering the time 20190819T07:20:00.000 to 20190819T12:50:00.000. This data set was collected during the MEX Extended Mission Phase 7 (EXT7) 2019 to 2020. There were four types of scientific measurements conducted during Extended Mission: Solar Conjunction, Occultation, Bistatic Radar and Gravity where one has to distinguish between gravity measurements conducted on Phobos as well as global gravity measurements on Mars which were conducted around apocenter and target gravity measurements on Mars which were conducted around pericenter over interesting geophysical structures. For more information see INST.CAT or the MaRS User Manual MARSUSERMANUAL2004. For all measurements if not indicated otherwise Transponder 1 onboard the s/c was used. Transponder 2 is designed to be a backup. Mission Phase Definition It should be noted that the Mars Express (MEX) Radio Science (MaRS) group uses mission phases which deviate from the ones defined in the MISSION.CAT files given by ESA in order to keep the keywords and abbreviations consistent for Mars Express, and Rosetta. For Venus Express other definitions are used. Those mission phase abbreviations are also used in the data description field of the dataset_id.

数据集概览：火星快车号（Mars Express，简称MEX）的无线电科学（MaRS）数据存档是一组按时间顺序排列的原始数据及部分处理数据，这些数据是在火星任务期间收集的。关于调查的更多信息，请参阅MaRS用户手册MARSUSERMANUAL2004，该手册位于MaRS文档/MRS_DOC文件夹中。该数据集涉及20190819T07:20:00.000至20190819T12:50:00.000期间的太阳 conjunction 测量。该数据集是在MEX扩展任务第7阶段（EXT7）2019年至2020年期间收集的。在扩展任务期间进行了四种类型的科学测量：太阳 conjunction、掩星、双站雷达和重力测量。在重力测量方面，需要区分在火星的火卫一上进行的重力测量以及在全球范围内进行的火星重力测量，这些测量是在火星的远地点进行的，以及围绕火星的近地点对有趣的地貌结构进行的重力测量。更多信息请参阅INST.CAT或MaRS用户手册MARSUSERMANUAL2004。对于所有测量，除非另有说明，否则使用了搭载在航天器上的应答机1。应答机2设计为备份。任务阶段定义：值得注意的是，火星快车号（MEX）无线电科学（MaRS）小组使用的任务阶段与ESA提供的MISSION.CAT文件中定义的任务阶段不同，目的是为了保持火星快车号、罗塞塔号的关键词和缩写的一致性。对于金星快车号，使用其他定义。这些任务阶段的缩写也用于dataset_id的数据描述字段中。MaRS任务名称 | 缩写 | 时间跨度
