摘要
卫星激光测距(SLR)是卫星轨道测量中精度最高的一种技术,广泛应用于卫星精密定轨、卫星轨道精度检核、激光时间比对等,是导航系统卫星轨道精确测定的重要组成部分。本文结合中国科学院上海天文台SLR系统及北斗卫星国际激光联测,取得全球激光台站观测数据,为实施全球导航卫星系统联合研究提供了条件;发展了100 kHz高重复频率SLR技术并应用于北斗卫星激光观测,标准点数据精度达百微米水平,有效提升了导航卫星激光观测数据质量;同时描述卫星激光测距技术在北斗导航系统其他应用情况,包括卫星独立定轨、广播星历精度检核、星地激光时间比对等。
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 100 kHz 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.
