This paper starts with the vibrating environment of the satellite, then analyzes the impact on the camera platform that brought by space environment. On the above basis, this paper introduces several researches and developments concerning micro-vibration measurement, satellite simulation system and on-ground test method, evaluates performance and retaliating method of measurement system which referring to the examples at home and abroad that are related to stable platform. Finally, based on national research achievement, this paper points out the developing direction about relevant technology.
