Algorithm with Patterned Singular Value Approach for Highly Reliable Autonomous Star Identification [PDF]
Sensors, 2020 In the work reported in this paper, a lost-in-space star pattern identification algorithm for agile spacecraft was studied. Generally, the operation of a star tracker is known to exhibit serious degradation or even failure during fast attitude maneuvers.

An Evaluation of Low-Cost Vision Processors for Efficient Star Identification [PDF]
Sensors, 2020 Star trackers are navigation sensors that are used for attitude determination of a satellite relative to certain stars. A star tracker is required to be accurate and also consume as little power as possible in order to be used in small satellites.
