What is a Star Tracker?
Star trackers or star sensors are optical devices that are used by satellites as a navigational tool to determine their orientation/attitude to the stars. The positions of stars are measured using a camera, photocells, and other onboard processing systems which identify the images and process the measured position in the reference frame of the spacecraft.…

Trending Star Trackers in 2024
A Star tracker is an optical instrument that measures the positions of stars using photocells or a camera. Since astronomers have precisely measured the positions of numerous stars, a star tracker on a satellite or spacecraft can determine the orientation (or attitude) of the spacecraft relative to the stars. In this article, SATNow has listed…
