摘要
利用GPS观测资料解算地球自转参数,用全球均匀分布的22个IGS跟踪站(IGS05)的连续观测资料估计地球自转参数(ERP),并与IERS C04(UTC 0时)的结果相比较,二者相差很小,均在IERS的ERP估计精度范围之内。基于即将建成的COMPASS全球连续监测与评估系统跟踪站,选择其网的8个IGS跟踪站的资料进行了解算并进行了分析和比对。
In this paper, the Earth rotation parameters are estimated with the GPS ob- servation data from 22 IGS sites in the ITRF2005 which have high accuracy coordinates and velocities, and the solutions were compared with the IERS C04 (UTC Oh) series. It shows that the difference between the two series is very small within the accuracy of the ERP esti- mated by IERS. In order to study the estimation of the earth rotation parameters based on COMPASS data from the tracking stations of future international COMPASS service system, observation data with the international COMPASS network of domestic stations and 2 foreign stations, together the 8 stations, were analyzed.
