摘要
随着我国空间探测工程的快速发展,对地球定向参数(EOP)的精度需求越来越高.通过对地球定向参数的测量原理进行介绍,以现有的经典光学观测手段、甚长基线干涉测量(VLBI)、全球卫星导航系统(GNSS)、多里斯系统(DORIS)、激光测月(LLR)和卫星激光测距(SLR)等为代表的现代空间大地测量手段对地球定向参数测量原理及特点进行全面的阐述,对地球定向参数的自主测量与服务进行展望,为我国建设自主的地球定向参数测量系统提供理论基础和参考.
With the rapid development of space exploration engineering in China,the demand for the accuracy of earth orientation parameters is higher and higher.This paper introduces the measurement principle of earth orientation parameters(EOP),comprehensively describes the measurement principle and characteristics of the existing classical optical observation means and modern space geodesy means represented by VLBI,GNSS,Doris,LLR/SLR,etc,and make a prospect of the autonomous measurement and service of EOPs.It also provides data basis for the establishment of autonomous earth orientation parameters measurement system in China.
