Preface
Attitude measurement is key and vital for spacecraft. It guarantees accurate orbit entrance and orbit transfer, high-quality performance of spacecraft, reliable space-to-ground communication, high-resolution earth observation, and successful completion of many other missions to be conducted in space. Star sensor is the core component in the autonomous high-quality attitude measurement of in-orbit spacecraft based on the observation of stars. By taking advantage of a star’s astronomical information, the star sensor method has the characteristics of good autonomy, high precision, and high reliability and can be widely applicable in space flight (celestial navigation). Generally speaking, star sensor works in two modes, namely, Initial Attitude Establishment and Tracking. The star sensor enters into the Initial Attitude Establishment Mode when it starts working or when attitude gets lost in space due to unforeseen problems. In this mode, full-sky star identification is needed because there is no available attitude information. Once initial attitude is established, the star sensor enters into Tracking Mode. Full-sky autonomous star identification is key in star sensor technological development, which has encountered many difficulties and th
