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.
