The author surveys algorithms used in star identification, commonly used in star trackers to
determine the attitude of a spacecraft. Star trackers are a staple of attitude determination …

The problem of estimating the state vector of a dynamical system from vector measurements
when it is known that the state vector satisfies norm equality constraints is considered. The …

Grid algorithm is a classical algorithm for all-sky autonomous star identification. However its
recognition rate decreases rapidly when the position and magnitude noise increases in the …

A full-sky star identification algorithm based on radial and dynamic cyclic patterns is
presented with the aim of solving the “lost-in-space” problem. The dynamic cyclic pattern …

For star sensors, the difficulty in realizing attitude determination lies in accurate and robust
star identification algorithms. In this paper, an efficient star identification algorithm is …

This paper describes the multilayer voting algorithm, a novel autonomous star identification
method for spacecraft attitude determination. The proposed algorithm includes two …

The star identification algorithm usually identifies stars by angular distance matching.
However, under high dynamic conditions, the rolling shutter effect distorts the angular …

Benefiting from rapid development of imaging sensor technology, modern optical
