Research on Improving the Precision of Solving GPS Long Base-line
With the expanding of application in GPS positioning technology, GPS reference stations of the continuous operation have been founded around the world. However, the positioning accuracy is related to different errors because of the sparse distribution of reference points and GPS long base-line. Among the distance errors, especially in the tropospheric delay the positioning accuracy reduces. In order to meet the needs of the GPS positioning accuracy, the precise tropospheric delay is computed by ordinary kriging interpolation method in this article. The accuracy of the solution will be improved by means of weakening the tropospheric delay. Finally examples are adopted to confirm the improvement of GPS positioning precision.
