摘要
简要介绍了目前应用广泛的两种重力场模型和多种GNSS水准高程拟合方法,并利用实测数据进行了高程拟合分析,通过对比分析,得到了采用基于EGM2008重力场模型的高程拟合方法可以达到四等水准测量精度的结论,为实际生产应用提供了参考依据。
This paper briefly introduces two widely used gravity field models and a variety of GNSS leveling anomalies fitting method,and use the measured data to do the fitting analysis. Through the comparative analysis, we get the height fitting based on the EGM2008gravity field model can reach the conclusion of the fourth-level measurement accuracy. The conclusion of this paper provides a goodreference for the actual production and application.
