Abstract:

This paper refers to a collaborative project to develop an accurate attitude determination system based on the combined use of gyros and star-crossing detectors. The latter are attractive for earth-pointing satellites but the intermittent nature of the data introduces complications, compared to star tracker systems. Background is given on the hardware, but the emphasis in on formulation of the estimating algorithm suitable for limited wordlength microprocessors, characterization of gyro drift, and estimation of overall performance both for low- earth and geostationary orbits.
