| 摘 要： | 在野外地质测量工作中,使用手持GPS(它属于WGS-84大地坐标系)导航时,当需要尽可能高精度的测量时,需要根据已知道的当地参数,和最近的已知点坐标(1954年北京坐标系或1980西安坐标系),通过计算,求取坐标转换的3个参数。

| Abstract: | In the geological survey work of ifeld, using the handheld GPS （that belongs to WGS-84 Geodetic coordinate system）, when need for high-precision measurement as far as possible, we should need known local parameters, and known coordinate of recent points （Beijing coordinate system 1954 or Xi’an coordinate system 1980）. By the calculation, we get the three parameters of coordinate transformation. |
