The third-generation satellite laser ranging system at Shanghai Observatory

The paper describes the performance of the third-generation satellite laser ranging system at the Shanghai Observatory, Academia Sinica, and the observation summary of Lageos, Ajisai and Starlette satellites in recent two years . It has been shown that the ranging accuracy of this laser ranging system is about 5cm(r. m. s. ), by means of satellite orbital fitting and the ground target ranging experiments.
