GNSS全自动解算软件研发及精度评估
|
摘要
根据载波相位差分定位技术,利用待定点周边稳定的CORS站网形成的区域误差改正模型,对待定控制点观测数据的噪声进行自动剔除,对电离层、对流层和多路径进行差分改正,研发GNSS全自动解算软件,并利用广西卫星定位基准站与待定控制点的GNSS观测数据对软件进行测试。结果表明,GNSS全自动解算软件具有较好的内外符合精度,其解算的三维坐标精度满足D级以下等级控制点的要求,可为工程测量应用提供新的自动化解算方案。
According to the carrier phase differential positioning technology, we used the regional error correction model formed by the CORS station network around the fixed point to eliminated the noise of the observed data automatically, corrected the ionosphere, troposphere and multipath, developed the GNSS automatic calculation software, and used the GNSS observation data of pending control points and Guangxi satellite positioning datum station to test the software. The results show that the GNSS automatic calculation software has good internal and external accuracy, and the 3D coordinate accuracy satisfies the requirements of the level control points below the level of D level, which can provide a new automatic calculation scheme for the application of engineering measurement.
