摘要
首先对GNSS高程拟合的曲面函数模型和平差模型进行阐述;然后分别借助TLS法和LS法,对GNSS高程曲面拟合模型进行参数求解;最后得出算例结算结果。结果显示,从理论方面来讲,相比LS法,TLS法更加严密,使用TLS法所得出的解算结果精度更高。
This paper first expounds the surface function model and adjustment model fitted by GNSS elevation;Secondly,the TLS and LS methods are sued to solve the parameters of GNSS elevation surface fitting model;Finally,the sample settlement results are obtained.The results show that from the theoretical aspect,the TLS method is more rigorous than the LS method and the TLS method is accurate.
