GPS Based Attitude Determination for Spinning Satellites
Abstract
This report describes the research performed by the Colorado Center for Astrodynamics Research (CCAR) under an AASERT Grant to study Global Positioning System (GPS) based attitude determination for spinning satellite. Two key contributions are discussed- phase-based methods for estimation of the spin axis of a spinning satellite. and signal noise ratio (SNR) based methods for estimation of one or more spacecraft axes. The latter method, which is very robust and widely applicable, is demonstrated on actual flight data from three NASA missions. It provides instantaneous pointing knowledge at the 310 degree level with a single GPS antenna and is useful for attitude initialization, verification, GPS phase ambiguity resolution, and a reliable backup attitude determination sensor.
