Process Analysis and Visual Interpretation Platform Design for Agile Satellite Dynamic Imaging

Agile Satellite, which has such characteristics as splicing Imaging, multi-attitude Imaging and nonparallel ground track imaging, has higher standards for test assessment of attitude maneuver. It is difficult to validate the complex maneuver mode using the existing assessment method of attitude angle and angular velocity. A platform of process analysis and visualization is designed to solve this problem. A method of calculating imaging trajectories base on the real time test scenarios proposed, to judge the real time imaging indexes such as imaging trajectory and mirror point moving speed. Real-time data visualization platform is also developed based on the two-way communication technology between Matlab and STK. The test results show that the designed platform can complete the process analysis and present an ocular demonstration of the complex maneuver, which provides theoretical references and utilities for system-level test and on-orbit task analysis.
