Moon-sun attitude sensor Academic Article uri icon


  • The basic ideas and the preliminary feasibility study of an experimental sensor for spacecraft attitude determination are presented. This instrument, based on a low-cost charge-coupled-device camera, is a moon tracker that records its images in the visible spectrum. The subsequent image processing enables this sensor to provide redundant data for attitude determination. Up to six different directions and two angles could actually be evaluated. The moon orbit and magnitude, the instrument operability, and the data reduction, as well as the attitude determination, have been briefly analyzed. The sensor cost is expected to be low, and its accuracy would increase with the complexity of the moon image processing software.
