摘要
介绍了2012年度上海天文台卫星激光测距系统常规观测情况。本年度更换了望远镜主副镜,提高了接收光学系统效率;使用高损伤阈值折轴发射光学系统,并改造了发射望远镜,满足了大功率激光测距和高发射效率的要求;完成了CRD激光数据格式更新工作,并把它应用于激光联测数据产品发布,以适应未来激光测距技术发展对数据格式应用需求。基于本测量系统,开展了地影中卫星激光主动照亮、异步应答式激光测距模拟测量等观测实验,促进了中国卫星激光测距技术的发展。
Abstract: This paper is a report on satellite laser ranging system at Shanghai Observatory in 2012. This year the primary and second mirror of the telescope with the aperture of 60 cm were updated so that receiving efficiency is also increased. Through using the new coude optical system with mirrors covered with the high damage threshold film and modifying the transmitting telescope the requirement of space debris laser ranging with high power of laser is met. The conversion of new CRD format for laser data was finished by improving the post-processing software and started being applied to the distribution of laser data produced by the stations participated in global tracking campaign. This new laser data format will perfectly meet the developing requirement of laser ranging technology. Based on the laser ranging system, the measuring experiments of laser active-illuminatingsatellites in the earth shadow and simulating measurements for interplanetary laser ranging with asynchronous transponder were implemented successfully to effectively promote the development of Chinese satellite laser ranging technology.
