In this paper, the structural forms of high-precision satellites are analyzed, and the new changes of boundary condition simulation when carrying out ground microvibration tests are discussed. Combined with the new requirements, the multi-stage unloading micro-vibration test method is studied, and the multi-stage unloading micro-vibration test system is designed, which lays a foundation for the follow-up micro-vibration test of a new generation of satellites.
