摘要
以ITRF、IGS等全球参考框架为例,简单介绍全球大地参考框架目前的研究进展和所面临的问题,在此基础上展开区域性参考框架的研究,主要介绍目前区域性参考框架的研究现状和实现方法。同时,基于全球性坐标框架ITRF的稳定性主要评估方法,提出了一种基于区域性参考框架转换参数的方法来评估框架稳定性。
It made a brief introduction of the most recent research of the InternationalTerrestrialReference Frame (ITRF), which also includes the challenges lie ahead, along with amore detailedanalysis of the regional terrestrial reference frame (TRF). Also a new method isproposed for the stability evaluation of theregional TRFby analysis the time series of the transform parametersbetween the regionalTRF and ITRF, which results from a major evaluation method of the ITRF.
