Autonomous Star Trackers in a Modern Attitude and Orbit Control System
The purpose of the study is to investigate the use of ASTs as sensors in modern AOCS. Relatively recently ASTs have developed into a mature technology offering high-performance autonomous attitude determination in relatively small packages.
The investigations into using ASTs used two different types of mission for reference. A large, high- performance scientific mission XMM, as one, and a typical geostationary telecoms mission as the other. Using baseline specifications for ASTs (AD(2) & AD(3)) the studies were performed with focus upon different aspects including:
