Abstract
The CCD Earth Sensor (CCDESA) is an attitude sensor that estimates three-axis attitude angles using the Earth’s images. Current Earth sensors detect infrared rays radiated by CO2, however, the CCDESA detects the Earth by acquiring visible rays with a Charge Coupled Device (CCD). This CCDESA is a mission sensor of μ-LabSat which was launched by H-IIA as a piggyback satellite in December 2002. This paper discusses the CCDESA and the results of the on-orbit experiments.
