High-resolution optical remote sensing satellites with high mobility have become an important development direction in recent years. Aiming at the system-level ground verification problems of such satellite tasks in orbit, this paper provides a test verification system design method based on multi-element combination and a corresponding test verification process management mode, which can effectively improve the effectiveness of system-level ground verification results, and improves the test verification process under such test mode to improve the efficiency of ground verification work. Finally, taking a certain type of satellite as an example, the test curve of this verification method is given, which proves the verification effect of this method on the joint verification of the complex working state of this kind of satellite, and provides a good reference for the development and project management of other such satellites.
