Satellite laser ranging (SLR) is the most accurate technology in satellite orbit measurement. It is widely used in high-precision orbit determination and satellite orbit accuracy checks for satellites, laser time transfer (LTT), and so on. It is an important part of accurately measuring satellite orbits in navigation systems. This paper describes the SLR system in the Shanghai Astronomical Observatory and the International joint survey of the BeiDou navigation system. The SLR international joint surveys for satellites of BeiDou 3 observation data were obtained from global laser stations in 2023, which provided conditions for the implementation of joint research on global navigation satellite systems. The high repetition frequency of 100kHz SLR technology has been developed, and applied to BeiDou satellites. The standard point data accuracy reaches the level of 100 um, which effectively improves the quality of navigation SLR observation data. At the same time, another application of SLR technology for the BeiDou navigation system was described, including independent satellite orbit determination, Broadcast ephemeris accuracy check, LTT, and so on.
