| Abstract: | The algorithm of transforming parameters in calculating coordinates could be easily affected by the double coordinate precisions of common points while production of GPS control network is transformed.This paper discusses one way to calculate parameters for coordinates transforming with high accuracy based on the theory of robust estimation.The example indicates that this way is practical and effective,and it's feasible in reality. |
