摘要
全球卫星导航系统(GNSS)高程拟合广泛应用工程建设,不同的拟合方法具有各自局限性,为提高高程拟合的适用性、可靠性和精度,本文提出综合利用EGM2008和移动曲面模型进行高程拟合,通过不同算例进行实验分析表明该方法能有效提高GNSS高程拟合精度.
GNSS height fitting is widely used engineering construction,different fitting methods have respective limitations.To improve the applicability,reliability and accuracy,this paper proposes a method to fit the height based on the EGM2008 and moving surface models,different experimental analysis shows that the method can effectively improve the precision of GNSS height fitting.
