MEX-X-MRS-1-2-3-PRM-0177

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 Solar Conjunction measurement covering the time 20040928T12:15:00 to 20040928T15:46:00. This data set was collected during the MEX Mission Prime Mission Phase (PRM) 20042005. This is a measurement of the radio sounding of the Solar Corona. It was done during the first solar conjunction season from 20040816 to 20041022. There were three types of scientific measurements conducted during PRM: Occultation, Bistatic Radar and Gravity where one has to distinguish between global gravity measurements which were conducted around apocenter and target gravity measurements 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, Venus Express and Rosetta. 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（MEX）无线电科学（MaRS）数据档案是一系列按时间顺序排列的原始及部分处理数据，这些数据是在火星快车号对火星的任务期间收集的。关于所提议的调查信息，请参阅MaRS用户手册MARSUSERMANUAL2004，该手册位于MaRS文档/MRS_DOC文件夹中。这是一个涵盖时间20040928T12:15:00至20040928T15:46:00的太阳联合测量。该数据集是在火星快车号首次任务阶段（PRM）20042005期间收集的。这是对太阳冕的无线电探测测量。这项测量是在20040816至20041022的第一个太阳联合季节期间进行的。在PRM期间进行了三种类型的科学测量：掩星、双站雷达和重力测量，其中必须区分在远地点附近进行的全球重力测量和围绕近地点在感兴趣的地球物理结构附近进行的目标重力测量。更多详细信息请参阅INST.CAT或MaRS用户手册MARSUSERMANUAL2004。对于所有测量，除非另有说明，否则使用搭载在卫星上的应答器1。应答器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有所不同，以便保持火星快车号、金星快车号和罗塞塔号的术语和缩写的一致性。这些任务阶段缩写也用于dataset_id的数据描述字段中。MaRS任务名称 | 缩写 | 时间范围
