| Abstract: | By conducting the static GPS control survey in the mining area and according to the actual needs of engineering maps in different coordinate systems,two sets of coordinates with three or more equal common points are selected to discuss the transformation of parameters of handheld GPS receivers.The transformation parameter is calculated through five-parameter transformation method to improve the positioning accuracy of hand-held GPS receivers. |
