【摘要】：中国大陆构造环境监测网络由260个连续全球定位系统观测站点和2 000个不定期全球定位系统观测站点构成,一般采用GAMIT或Bernese高精度数据处理软件进行处理。由于GAMIT及Bernese软件对测站数处理能力的限制,必须对陆态网连续运行基准站进行分区解算。针对这一问题,为研究不同分区方案对陆态网解算精度的影响,该文基于全国55个陆态网络连续运行基准站数据,采用整网解算方案以及间距分区法和区域子网划分法分别进行解算,并以整网解算结果作为标准值,对比两种分区方案与整网解算方案的基线长度差及坐标差。结果表明,间距分区方案解算精度比区域子网划分方案精度高,可实现对陆态网分区的高精度解算。最后利用间距分区法对全国240个陆态网络连续运行基准站进行分区解算,得到了较高精度的解算结果。
[Abstract]:The tectonic environment monitoring network in China consists of 260 continuous GPS observation stations and 2 000 irregular GPS observation stations, which are generally processed by GAMIT or Bernese high-precision data processing software. Due to the limitation of GAMIT and Bernese software on the number of stations, it is necessary to calculate the land network continuous operation reference stations. To solve this problem, in order to study the influence of different zoning schemes on the calculation accuracy of land state network, this paper is based on the data of 55 continuous operation reference stations of land state network in China. The whole network solution scheme, the interval partition method and the area subnet partition method are used to solve the problem, and the results of the whole network solution are taken as the standard values to compare the baseline length difference and coordinate difference between the two partition schemes and the whole network solution scheme. The results show that the resolution accuracy of the spaced partition scheme is higher than that of the regional subnet partition scheme. Finally, the method of spacing partition is used to calculate 240 land network continuous operation reference stations in China, and the results are obtained with high accuracy.
