摘要
介绍了OmniStar星基差分服务的工作原理及其特点,通过测试数据验证其定位精度的稳定性和收敛速度。通过长时段定位结果与IGS联测数据的对比,分析了OmniSTAR星基差分静态定位精度状况和收敛时间,讨论了利用这种技术在物探测量中获取精确WGS84起算坐标的可行性。
This article analyzed the accuracy level and work stability situation of OmniSTAR SBAS serves via processing several observation data and analyzing these results. It analyzed accuracy and feasibility of SBAS to obtaining an accurate coordinates in WGS84 system for building a surveying control network when no available existing controls by compared the average coordinates of hourssession static observation by SBAS and the coordinates obtained by tying to IGS stations.
