With the development of space technologies, the optical payload requirement on the pointing accuracy becomes higher and higher. The active vibration isolation is an effective way to improve the pointing accuracy of the optical load, and the six freedoms Stewart Platform is widely adopted in the active vibration isolation for spacecrafts. The double-layer structure is adopted for the single leg of the Stewart Platform and the parameters of the passive part are optimized by the GA algorithm. For the active part, the L1 method is used for solving the problems in the vibration isolator because of the impact load. The simulation results indicate the effectiveness of the L1 method for solving the problem.
