ODCC: A Dynamic Star Spots Extraction Method for Star Sensors

IEEE Transactions on Instrumentation and Measurement, 2021
In this article, we consider the problem of extracting star spots for traditional star sensors under highly dynamic conditions. Under this setting, it is difficult to effectively extract star spots with a low signal-to-noise ratio (SNR), resulting in a failure to estimate the attitude of star sensors.

Star sensor specification standard

2003 European Control Conference (ECC), 2003
In recent years there have been rapid developments in star tracker technology, in particular with great increases in the level of sensor autonomy and the associated capabilities. The variety of sensors now available, combined with the complex on-board algorithms, has led in general to disparate and manufacturer-specific sets of performance ...

Fast star tracking technology in star sensor

SPIE Proceedings, 2006
A fast star tracking algorithm is proposed. In order to speed up the star tracking, three techniques including star catalogue partition, threshold mapping and sorting & matching are designed for three time-consuming portions in tracking algorithm,. Star catalogue partition divides the celestial sphere into small partitions.
