摘要
主要探讨了GPS坐标转换的方法,对两种不同的转换方法进行了数值稳定性和精度分析,结果表明:空间七参数转换方法可适用于大范围的坐标转换,但方程经常病态,稳定性差,平面相似变换法方程相对稳定,但只适用于小范围的坐标转换。
The GPS coordinate conversion method was introduced mainly, and the numerical stability and precision of two different conversion methods were analyzed. The results indicated that the spatial seven parameters conversion method adapted to large scale coordinate conversion, but the equation always was ill and stability was had, while the equation of plane similar conversion method was relative stable, but only adapted to small scale coordinate conversion.
