| Abstract: | The paper deals with the problem of the fixed initial point compatibility when the results of GPS survey was transformed into the ground coordinate system. Based on the robust estimating principle. the coordinate transformation formulas and the internal geometry and accuracy information in GPS network. We succesfully select the fixed initial point matching with GPS network. the calculating results express this method is very simple and efficient. |
