The mass trim mechanism (MTM) is used to precisely trim the mass characteristics of satellite in orbit and ensure that the satellite can provide high-precision orientation and orbit control and part of the payload can work normally. In order to ensure high-precision trim and light miniaturization, the mass trim scheme of the satellite and the MTM are designed, and the mass block moving range of the mechanism is ±145 mm. The adjusting scheme, system composition, and working principle are introduced particularly, and the screw-guide mechanism is proposed to realize the trim function. The position precision can satisfy the requirement of the design index by the theoretical calculation to get the precision of the trim mechanism. The data before and after the environmental experiments indicate that the displacement error is less than 0.06 mm and the movement parallelism of the mass block is less than 0.04 mm, which meets the requirement for use. Theoretical calculation and experimental results prove that this MTM has stable structure, high positioning accuracy, wide adjust range, environment adaptability extensive features to meet the purpose of precise trim of space satellite mass.
