摘要
通过在矿区施测的静态GPS控制测量,根据实际不同的坐标系工程用图需要,在矿区内均匀选择三个以上公共点的两套坐标,探讨对手持式GPS接收机求取其转换参数的方法,采用五参数转换法,求出转换参数,然后在手持GPS接受机上设置五参数来提高定位精度。
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.
