GPS数据处理中为了满足不同的需要，处理的数据要进行坐标转换，得到在不同坐标系统下的结果，下面是笛卡尔坐标系，大地坐标系，站心地平坐标系（线型和极坐标形式）之间的转换源代码-GPS data processing in order to meet the different needs of data processing for coordinate transformation, the coordinate system in different results, the following is a Cartesian coordinate system, the earth coordinate system, stop-ping carefully coordinate system (polar coordinates the form of linear and ) conversion between the source code
