Definition
- The Advanced Stellar Compass (ASC) calculates the pointing direction of a CCD camera from a star image of the sky. The direction is found fully autonomous with arc seconds accuracy. The ASC comprises one or more CCD cameras and a Data Processing Unit. The main application of the Advanced Stellar Compass is on-board attitude determination for a satellite. The ASC was originally designed and developed to fly onboard the Danish Geomagnetic Research Satellite Ørsted. Ever since, the Advanced Stellar Compass has evolved into a more compact and sophisticated instrument that has flown on several missions including Astrid II, TeamSat, CHAMP, PROBA and GRACE. Furthermore the ASC has been chosen to participate in several other projects.
