Paper Abstract

This paper presents design and performance of a high- precision star tracker which has been developed for use in the attitude determination and control system of MUSES-B spacecraft; the space segment of space VLBI program called VSOP (equals VLBI Space Observation Program). The MUSES-B is being prepared for launch in September 1996. The attitude control system is required to fulfill an overall pointing accuracy of 0.01 degrees (3 sigma) of an 8 meter-diameter VLBI antenna mounted on the spacecraft. The onboard attitude determination system is based on a reset type Kalman filter that assures the overall attitude determination accuracy of 19 arcseconds, using outputs from the star trackers and the gyroscope-based inertial sensors. For this purpose, the star tracker is designed to provide star position detection accuracy of 4 arcsec random (1 sigma) plus 15 arcsec bias error. This paper describes the design of the STTs, the performance analyses, and ground test results of the Protoflight Model.
