Abstract The next generation of CubeSats will require accurate attitude knowledge throughout orbit for advanced science payloads and high gain antennas. A star tracker can provide the required performance, but star trackers have traditionally been too large, expensive and power hungry to be included on a CubeSat. This paper briefly surveys the state of current CubeSat ADCS systems and goes on to describe the development of a CubeSat-compatible star tracker. Algorithms for star detection…

A Survey on Star Identification Algorithms

Algorithms used in star identification, commonly used in startrackers to determine the attitude of a spacecraft are surveyed, including algorithms that use a star camera with an imaging array and analgorithm to match observed directions of stars with catalog directions ofStars without requiring reorienting the camera or the spacecraft.

Evaluation of Star Identification Techniques

Traditionally, star sensors have used fairly large e elds of view and bright stars to perform tracking and identie cation. Recent trends in space missions have brought out the need for smaller e
