Abstract
Stellar navigation using star trackers require precise radiometric and spatial calibration of the instrument over multiple environmental variables. Calibration accuracy is critical for high performance star trackers such as the Ball High Accuracy Star Tracker (HAST). This paper discusses calibration methods and capabilities that allow for sub-tenths of seconds of arc performance achieved by the HAST.
