Star trackers are a reliable and accurate device used by almost all spacecraft in order to autonomously determine their orientation.
The VIGILANTE project is a planned vision system capable of tracking and recognizing targets in real time, on a small airborne platform.
Charge-Coupled Device (CCD) based star trackes provide reliable attitude estimation onboard most 3 axis stabilized spacecraft. The spacecraft attitude is calculated based on observed positions of stars, which are located and identified in a CCD image of the sky.
