Star Tracker
Star Tracker is an instrument used in spacecraft to determine the orientation of the vehicle with respect to the stars. It consists of a camera that takes images of the star field and a processor that analyzes the images to identify the stars and calculate the spacecraft's attitude. Star trackers are highly accurate and can provide attitude information even in the presence of strong disturbances such as solar radiation and magnetic fields. They are essential for many space missions, including those that require precise pointing of scientific instruments or antennas, or those that need to maintain a stable attitude for long periods of time.
