摘要 介绍下一代美国GRACE FollowOn和欧洲E.MOTION（Earth System Mass Transport Mission）卫星重力测量计划的研究进展，以期为我国下一代PostGRACE卫星重力测量工程的成功实施提供参考依据。详细阐述了我国下一代PostGRACE卫星重力测量工程的研究意义和科学目标，建议我国先期构建卫星精密定轨和卫星重力反演仿真模拟软件平台系统，开展重力卫星关键载荷误差分析研究，以及执行卫星重力测量任务需求。
Abstract：]The progresses in the nextGeneration American GRACE FollowOn and European E.MOTION satellite gravity measurement missions are respectively introduced for the sake of providing a reference for the nextgeneration satellite gravity measurement mission in China. Finally, the research significances and scientific objectives of the nextgeneration PostGRACE satellite gravity measurement mission in China are expatiated in detail. We propose that the software platforms of precise orbit determination and satellite gravity recovery should be established as soon as possible, the error analyses of key payloads of gravity satellite should be developed in advance, and the mission requirements of satellite gravity measurement should be carried out as early as possible.
