orbit space
1.- To establish a multi-function and multi-orbit space infrastructure composed of various satellite systems and set up a satellite ground application system that harmonizes spacecraft and ground equipment to form an integrated ground-space network system in full, constant and long-term operation in accordance with the overall planning of the state; 
2.After described the mechanical and thermal environments during launching period and in orbit period of space camera, the main support structure optimization design method of space camera is brought forward. Based on the method, two kinds of main support structure of space camera with Cassegrain and TMA optical system are optimized by Finite Element Method.
7.Through much research into methods on autonomous orbit determination of deep-space explorer, an autonomous optical navigation scheme based on UD and EKF was proposed to determine the circling orbit state in time, in which star sensor and navigation camera are used in measuring special angles between planetoids and explorer.
