Opto-electrical compound axis tracking control technology on satellite

It's becoming a research hot topic that two axis opto-electrical tracking instrument is loaded on satellite to continuously track and observe moving target in space. At present, there are Space-Based Space Surveillance System (SBSS), Space Tracking and Surveillance System (STSS) and Precision Tracking and Surveillance System (PTSS). In order to deal with stable tracking control technology for opto-electrical axis on the condition of dynamic platform on satellite, firstly, simplifying physics model of opto-electrical tracking control system on satellite. Secondly, solving relative angular velocity and acceleration between two satellites near sun-synchronous orbits. Thirdly, analyzing active stable tracking control scheme and principle based on opto-electrical compound axis tracking control system. Lastly, establishing simulation model of opto-electrical compound axis tracking control system on satellite. And the results show that stable tracking precision is 2.5 for space object in the relative maneuvering range of (37.68 ()/s、47.33 ()/s) and space satellite that relative low velocity is 0.1 ()/s.
