摘要：
A software system for a star imager for 'on-line' satellite attitude determination is described. The system works with a single standard commercial CCD-camera with a high aperture lens and an on-board star catalogue. It is capable of both an initial coarse attitude determination without any a priori knowledge of the satellite orientation and a high accuracy attitude determination based on prediction and averaging of several identified star constellations. In the high accuracy mode the star imager aims at an accuracy better Satellitec sec. with a processing time of less than a few seconds. The star imager is developed for the Danish 'micro satellite' Oersted.
