摘要
根据GPS水准高程拟合的试验成果 ,从拟合的似大地水准面精度、己知点高程精度和GPS点大地高精度三个方面 ,分析了GPS水准高程拟合的精度 ,总结了提高GPS水准高程拟合精度的方法。
In line with a test achievement of GPS levelling height fitting, fitting accuracy of GPS levelling height is analyzed from the three aspects of the precision of fitted quasi-geoid, height of fixed points and ellipsoidal height of GPS points. And lastly, some methods to heighten fitting precision of GPS levelling height are summed up.
