Paper Abstract

A typical configuration of attitude estimation system for a spacecraft consists of multiple star trackers, coupled with gyroscopes and coarse sensors such as Sun or Earth sensors. The combination of these sensors results in high mass, volume and power requirements. StarVision has been actively developing an unique sensor that is capable of providing attitude and angular rate information from star measurements at update rates of 100Hz. The SG100 stellar gyroscope is built around an image intensified imaging core that is sensitive to stars as faint as visual magnitude 10 at very small exposure times. In this paper we report the development of the SG100 sensor. Results from sensitivity analysis as well as night sky tests at angular rates as high as 20deg/s will be presented. Test data shows that the SG100 far exceeds the requirements of star sensitivity and noise levels even under non-ideal imaging conditions.
