摘　　要：GPS定位技术已经被广泛应用,但由于GPS观测测量是基于以地球质心为原点的空间直角坐标系,而对于采用54北京坐标或者其他地方坐标而言,就需要解决如何将这些坐标系统转换为我们需要的坐标系统这一问题。本文就这一问题出发,以软件方法进行问题的探究解决。Abstract： GPS positioning technology has been widely used, but the GPS observation is based on the earth~ center for the origin of the coordinate system in space. For the 54 Beijing coordinate or other local coordinate, we need to address how these coordinate systems are converted to the coordinate system we need to solve this problem. Thepaper uses software method to realize the conversion of differ- ent coordinate systems.
