Qi, “On-orbit high-accuracy geometric calibration for remote sensing camera based on star sources observation,” IEEE Trans. Geosci. A star tracker is an optical device that measures the positions of stars using photocells or a camera. As the positions of many stars have been measured by astronomers to a high degree of accuracy, a star tracker on a satellite or spacecraft may be used to determine the orientation (or attitude) of the spacecraft with respect to the stars. In order to do this, the star tracker must o…
