Abstract: According to the demand of high accuracy stabilized platform of shipborne, combining two-stage stabilized platform scheme was designed. Coarse stage stabilized platform is an intestinally stabilized platform including a two-degree-of-freedom gyro and two accelerometres. For the connatural precision of the gyro, a basal steady state was obtained by the coarse stage stabilized platform which ensured seeing the target. In order to reach the highaccuracy target tracking, and avoiding the shake of the sight axis, and result in the blurry image, the accurate stage stabilized platform was designed. Combing twostage stabilized platform is analyzed and designed. The structural design and ANSYS analyses were introduced and analyzed particularly.
