摘要
手持GPS使用的坐标系统是WGS-84坐标,在普通测量中,可使用5参数法转换到54北京坐标系或80国家坐标系。首先收集或采集2到3个北京坐标系x、y、B、L、h、ξ值和WGS-84坐标系B、L、H值,根据大地坐标系与空间直角坐标系的转换关系,求取相应三维直角坐标,然后利用参数转换公式求取5个转换参数DX、DY、DZ、DA、DF。
The coordinate system GPS handset used is WGS-84 coordinate system, in ordinary surveying, 5 parameters method can be used to converse it to 54 Beijing or 80 state coordinate systems. Firstly collect 2 to 3 Beijing coordinate system x, y, B, L, h and ξ values and WGS-84 coordinate system B, L and H values, according to conversion relationship between geodetic coordinate system and spatial rectangular coordinate system, to derivate corresponding 3D rectangular coordinate, then use parameter conversion formula derivate 5 conversion parameters of DX, DY, DZ, DA and DF.
