论LC组合观测值系数的选定

Discussing the Selection of Coefficient of LC Observation

在详细推导出GPS组合观测值公式的基础上，重点讨论了GPS相对定位中一种很重要的组合观测值─—LC系数的选定问题，导出了两个不同形式的LC系数关系方程；之后分析了造成这种差异的原因，通过分析与计算，验证了这两个关系方程差异极小，可以忽略它们之间的差异．

Based on the detailed derivation of GPS combined observation formula, theselection of coefficient of LC observation which is a very important observation in.GPS relatively positioning is emphatically discussed, and two LC coefficientequations are obtained. The reasons resulting in the difference between twoequations are analysed, According to analysis and computation. It is proved thatthe difference is in fact so little that it can be ingored.
