The singular values are important invariant features in singular value decomposition (SVD) method for autonomous star identification. This paper theoretically analyzes the inherent relationship between the star vectors in field of view (FOV) and the eigenvalues of the Hermitian matrix formed by star vectors, which is performed as an equivalent study on singular values of the star vector matrix. Firstly,...
A star identification algorithm Based on finite automata is proposed in this paper. Firstly, each star is characterized by a well-defined pattern that can be determined by its surrounding stars and generated with a virtual circle. Then, the star pattern is coded into strings and a guide catalog is also constructed according to the generating process of the star pattern. Finally, a string matching...
