| APT System of Mult-Axis Self-stabilization high precise Satellite Laser Communication is a very important platform for modern communication. Not only could support and keep gesture, but the more import to close off vibrations or interfering from transferring to system, enhancing the stability of system. It also keep the all right gesture when the carrier is in orbit, accelerating or decelerating or swerving suddenly. It makes the progress of tracing more precise, and reduce fault rate. So, it's significative to design a excellent Self-stabilization platform.In this paper, statics model of Self-stabilization framework is built on the base of analyzing the popular used Self-stabilization Peg-top. The fact of infection of Self-stabilization adequately is considered, such as radius, mass and volume. Some academic analysis, such as material and structure, about the infection to Self-stabilization platform is taken. The Two-Axis platform and important measure sensor's calibration are researched carefully. Build a primary designing model on the base of so much work above. Something about the main research work and feature of the paper as follow:1. Build a model of experimental Self-stabilization platform according to therequest of designing, which has a simple structure and excellent performance of mechanics. Claim the standard of choosing the important parts.2. Build finite element analysis model of the important parts in the Self-stabilization platform, and analyze the rigidity of main parts and intrinsic frequency of the whole system. On the base of analyzing of model, optimize the structural parameters of the important parts.3. Design a simpler method of Camera calibration, which establishs the material progress of calibration, and validate the dependability of the method.
