Star Identification Based on Multilayer Voting Algorithm for Star Sensors [PDF]
Sensors, 2021 This paper describes the multilayer voting algorithm, a novel autonomous star identification method for spacecraft attitude determination. The proposed algorithm includes two processes: an initial match process and a verification process. In the initial match process, a triangle voting scheme is used to acquire candidates of the detected stars, in ...

An Optical System of Star Sensors with Accuracy Performance Varying with the Field of View
Sensors, 2023 The field of view and single-star measurement accuracy are crucial metrics for assessing the performance of a star sensor. The field of view determines the spatial range of stars that can be captured by the sensor, while the single-star measurement ...

A Fast Star Identification Algorithm of Star Sensors in the LIS Mode
Remote Sensing, 2022 In the South Atlantic Anomaly (SAA) area, due to the influence of transient noise caused by space radiation, a star sensor can easily stay in the lost-in-space (LIS) mode for a long time. To solve this problem, this paper proposes a fast star identification (FSI) algorithm.

Star Centroiding Based on Fast Gaussian Fitting for Star Sensors [PDF]
Sensors, 2018 The most accurate star centroiding method for star sensors is the Gaussian fitting (GF) algorithm, because the intensity distribution of a star spot conforms to the Gaussian function, but the computational complexity of GF is too high for real-time applications.
