摘要
GAMIT 10.7软件实现了对BDS数据的解算,高精度BDS数据处理软件和方法对我国卫星导航定位相关产业的发展有重大意义。该文基于GAMIT/GLOBK对2016~2019年BDS和GPS连续观测数据进行基线解算和坐标网平差。结果表明,BDS与GPS短基线解算精度为毫米级差异,长基线差异基本都在10mm以内波动(个别天数除外);BDS和GPS在N、E、U三方向平均坐标重复性差异为亚毫米级,两种定位系统的夏季解算精度低,冬季解算精度高。
The GAMIT 10.7 software realizes the BDS date processing, and the high-precision BDS data processing software and methods have great significance to the development of China′s satellite navigation and positioning related industries. In this paper, based on GAMIT/GLOBK, the baseline solution and coordinate network adjustment of BDS and GPS continuous observation data from 2016 to 2019 are carried out. The results show that the short baseling solution accuracy of BDS and GPS is millimeter level, the long baseline difference fluctuates within 10 mm(except individual days).The average coordinate repeatability difference of BDS and GPS in N, E, and U is submillimeter level. And the solution accuracy of the two positioning systems is poorer in summer, it is higher in winter.
