卫星激光测距(SLR)技术因测量精度高而广泛应用,但由于涉及多门学科领域使得系统复杂,制约了自动化水平提高,影响着该技术的发展和推广应用。基于上海天文台SLR系统平台,分析了SLR的操作流程,提出光学系统、伺服系统、控制系统及远程监控管理系统等自动化发展方向,设计了角秒级精度光束指向瞄准方法,研制了精度为1″的小型化伺服控制系统,实现了观测模式的快速切换,并搭建远程监控管理系统,使整个SLR系统的自动化能力得到提高,减少了人力操作,提高了观测效率。应用上述研究成果,在国内成功进行了SLR的远程控制实验,实现了SLR系统的异地操作和监控,为SLR的全自动化及远程控制应用奠定了技术基础。
Satellite laser ranging(SLR) technology is widely used because of its high precision. But the system is com- plex because it involves multi-disciplines. This restricts its automation level, and influences the development and ap- plication of the technology. Based on Shanghai observatory SLR system, the operation process was analyzed, and the automation development direction of optical system, servo system, control system and remote monitoring management system was analized. A method of beam pointing with second of arc precision was designed. A small size servo control system with 1"accuracy was developed. The rapid switching of observation model was achieved, and the remote monito- ring management system was set up. This improves the automation ability of the system, reduces the human operation burden and improves the efficiency of the observation. The SLR remote control experiment has been successfully car- ried out in domestic by the application of the research results above. The research lays a technical foundation of the full automation and remote control application of SLR.
