The Attitude Ground Support System (AGSS) at Goddard Space Flight Center provides ground attitude support for the High Energy Astronomy Observatory (HEAO) missions. The AGSS uses information telemetered from sun sensors, gyroscopes, star trackers (STAs), and an onboard computer to calculate updates to the onboard attitude reference and gyro calibration parameters. This paper presents the procedures used by the AGSS in computing reference and calibration updates; it also provides HEAO-1 postlaunch statistics that illustrate the ability to maintain 0.25-deg accuracy in the onboard attitude reference. Simulated HEAO-B results show an improvement in reference accuracy through the use of calibration maneuvers.
