GNSS精密单点定位成果的框架与历元转换方法
Method Research on Reference Frame and Epoch Transformation of GNSS Precise Point Positioning Result
摘要
Abstract
Static precise point positioning can reach the centimeter level,but the positioning is an average of many epochs' coordinates in any ITRF.The point coordinates in any ITRF and epoch can be obtained by the conversion of frame and epoch.In this paper,93 d of data from the continuously operating reference station are processed by online GNSS data processing software,including APPS,CSRS,GAPS,magicGNSS and AUSPOS.Then,the positioning is converted into the CGCS2000 coordinate system by the conversion of frame and epoch.The results show that the average precision of the PPP results of 24 h is 1.7 cm.When we transform the PPP results of 24 h into CGCS2000 coordinate system with the velocity field in ITRF2008 provided by crustal movement observation network of China and the natural neighbor interpolation method,the transformed precision is 1.6 cm.关键词
