摘要
针对北斗卫星导航接收机在CGCS2000大地坐标系中定位解算得到的大地高度向海拔高度转换的问题,提出了一种基于加权格网拟合和Lagrange拟合的混合拟合算法。通过仿真比较混合拟合算法和传统曲面拟合算法的拟合性能,仿真结果证明该算法有更高的拟合精度和实用性。
The paper proposes a hybrid fitting method based on grid fitting and Lagrange fitting, considering the problem about altitude transformation in the coordinate system of CGCS2000.The fitting performance of the hybrid fitting and the traditional surface fitting is compared by simulation, and the results show that the hybrid fitting has better fitting precision and practicability.
