Spacecraft Attitude and Body Rate Estimation with Star Sensors and Their On-Orbit Verification Results

Abstract: We have developed Satellite controller Integrated with Star sensors (SIS) as a prototype of a future small and low-priced satellite controller. To reduce size and cost of the controller, SIS integrates attitude sensors into star sensors with medium resolution and medium sensitivity, adopts Commercial Off-The-Shelf (COTS) electrical parts for key parts such as CPU and CCD, and integrates several electronics for star identification, attitude determination, attitude control, and data handling into a single proces… Show more

“…The sensors for this mode need to have a high reliability and high availability. Despite of having higher pointing knowledge, star trackers are not used in this mode, 14) due to their high power consumption and lower reliability. Thus, only sun sensor and magnetometer information will be used.…”
