摘要：

The science objective of the Danish Geomagnetic Research Satellite "Orsted" is to map the magnetic field of the Earth, with a vector precision of a fraction of a nanotesla. This necessitates an attitude reference instrument with a precision of a few arcseconds onboard the satellite. To meet this demand the Advanced Stellar Compass (ASC), a fully autonomous miniature star tracker, was developed. This ASC is capable of both solving the "lost in space" problem and determine the attitude with arcseconds precision. The development, principles of operation and instrument autonomy of the ASC is described. This is followed by a description of test and performance verification methods, and finally key physical and performance data are given. (C) 1997 Published by Elsevier Science Ltd.
