抵偿坐标系投影变形检核方法与误差分析

摘要

This paper with the GPS plane control project grade E network of the project of Jishixia Land derelopment and land smoothing as an example, this paper introduces the method of the horizontal distance measure and analyzes the error influence in the observation process and checks the accuracy.%以检核积石峡百万亩土地开发整理项目中的GPS平面控制E级网为例,介绍实测平距的方法与观测过程中的误差影响,并以实测平距为最或是值检核抵偿坐标系坐标反算平距相对精度是否满足不大于1/40000的精度要求。
