提出在已有GPS高程转换函数模型的基础上,通过增加随机模型以提高GPS高程转换精度,并以二阶多项式拟合函数模型增加随机模型为例,验证了该方法能进一步提高GPS高程转换精度。
The method based on existing GPS height transformation function model with increasing the stochastic model is put forward to improve the accuracy of GPS height transformation.Through a case of increasing stochastic model on the second-order polynomial fitting model,it proved that with this method the accuracy of GPS height transformation can be improved more.
