trigonometrical interpolation

It discusses the spatial correlation of local area differential GPS,and introduces several common methods,such as weighted average method,linear interpolation method,low-order surface model,triangle interpolation algorithm,and analyses interpolation coefficients and interpolation quality fact.

文中针对局域差分GPS的数学模型空间相关性,介绍几种常用的内插方法,如加权平均法、线性内插法、低次曲面模型法及三角形内插法,并分析各种方法的内插系数和内插质量因子。
