基于GNSS基准站的三级GPS网解算精度分析

随着连续运行基准站技术在大地测量中的广泛应用,连续运行基准站在全国三级GPS网中的布设和数据处理也起到了关键作用,不仅加快了建设速度,加大了布网的灵活度,也保证了起算控制和解算精度.与以前相比,陆态网连续运行基准站分布密度总体上提高了10倍,重点地区提高了100倍,观测手段也有了很大变化.基于网络工程和陆态网络基准站对...

ACCURACY ANALYSIS OF THIRD-ORDER GPS GEODETIC NETWORK BASED ON GNSS STATION

With the use of Continuous Operating Reference Station(CORT) technology in geodesy of large scale,it plays a key role in station distribution and data processing of the third order GPS geodetic network. This technology not only accelerates the construction speed, increases the network flexibility, but also ensures the initial control and calculation accuracy. Compared with the previous situation, the CORT distribution density increased to 10 times totally, in key areas increased to 100 times. The observing means also have very great changes. On basis of the station of Chinese crustal motion network and CORT, the calculation and accuracy statistics of the third order GPS geodetic network had been carried out in different areas. By contrast, the latter has the higher accuracy of third order GPS geodetic network.
