摘要
基于Ozone算法的GPS大地坐标变换,采用WGS-84地心坐标系。其基本参数包括椭球体长/短半轴和体扁率、地球引力常数及自转角速度等。该算法无需迭代,即可由大地直角坐标直接求出地理坐标。其算例只考虑经纬度二维情况可满足精度要求,并提高数据处理效率。
WGS-84 geocentric geodetic coordinate system was adopted for GPS geodetic coordinate transformation based on Ozone algorithm. Its basic parameters include long/short half axis, spheriform oblateness, gravitational constant G and self-rotating angular velocity of the earth. The algorithm could get geodetic coordinates from geodetic rectangular coordinates directly without considering iteration. The example only considered the longitude and latitude. Comparing with traditional iterative algorithm, the method could get a high precision and improve efficiency of data processing.
