Gyroless fine pointing on Small Explorer Spacecraft
Abstract
Recent advances in spacecraft attitude control system hardware have allowed engineers to develop innovative controls concepts which were deemed impossible just a few years ago. Gyroless attitude control designs using CCD star trackers have been discussed several times in the literature. The research presented here is an extension of these ideas; that is to obtain fine pointing jitter performance without gyros. A strawman gyroless attitude control system design was developed for a SMall EXplorer (SMEX) sized spacecraft in a High Earth Orbit. In addition, spacecraft performance drivers were determined and jitter performance results are presented.
