实时精密单点定位中的数据预处理研究

Data Preprocessingin Real-time Precise Point Positioning

提出了适用于实时环境的一套数据预处理方案,包括钟跳修复、联合使用Geometry-Free和Melbourne-Wübbena组合进行周跳探测。通过丰富的实验算例,说明了对观测值进行钟跳修复的必要性;证明了联合使用GF与MW组合能够准确有效地探测出实际数据中存在的以及手工模拟加入的周跳。

We propose a set of data pre-processing strategy for real-time environment,including clock jumps repairing,cycle slip detection using G-F and M-W combination.From the extensive experimental study,we can explain the need of clock jumps repairing for observations.And the joint use of G-F and M-W combination can accurately and effectively detect the actual and manual simulation added cycle slip.
