| 摘 要： | 在GPS精密单点定位数据处理中，通常采用基于非差观测值的处理方法。然而精密单点定位也可通过观测值不同差分组合以减少某些未知参数，且在理论上与非差模型等价。文中介绍基于非差和差分模型的精密单点定位的几种数据处理方法，并对各种模型进行比较。

| Abstract: | In the data processing of GPS precise point positioning,the un-difference method is used commonly.However,observations can be different in order to decrease some unknown parameters.The different approach is mathematically equivalent to un-differene approach in theory.This paper introduces several data processing methods,including un-difference model and difference model,and draws some conclusions from the present paper. |
