| 摘 要： | 本文通过联测IGS跟踪站获取南宁地区若干控制点的ITRF框架瞬时历元坐标,并根据IGS跟踪站速度内插出南宁地区地壳板块运动速度,从而将控制点ITRF坐标进行历元转换与框架转换;同时根据南宁某CORS站观测值所求板块运动速度,对相关结论进行验算。结果表明:基于准确的板块运动速度场,采用历元与框架转换方式求取CGCS2000坐标能够满足小区域GPS控制测量的精度要求。

| Abstract: | In this paper,the crustal velocity of Nanning region was computed by interpolating the velocities of IGS tracking stations that belong to the same crustal plate nearby.Then the coordinates of test control points in ITRF2005 were transformed.Furthermore,comparing with the velocity feild computed from Continuously Operating Reference Stations(CORS) in Nanning,the newly coordinates transformation method was verified to be able to fully meet the requirement of small region GPS control survey. |
