Other AbstractThe large radio telescope reacquires rigorous pointing performance, and its pointing performance can be influenced by much more factors due to its large scale. The conventional pointing measurement method would be time-consuming because of the telescope’s large inertia. An accurate direction measurement of the receiver cabin structure can transform the pointing measurement and correction problem into some less complex problems. The star tracker can provide pointing measurement data of sub-arcsecond precision at several Hz update rate, which satisfies the measurement needs well. We introduced the scheme to pointing the telescope with assistance of star trackers, and presented application examples of them on some radio telescopes. At last, we discussed some specific requirements of the star tracker used on large radio telescopes and the possibility of low-cost solutions with commercial cameras.
