Abstract
The science objective of the Danish Geomagnetic Research Satellite
"Ørsted" 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, and key physical and performance data are
given.
