GPS-RTK点校正方法的对比分析

首先介绍了GPS—RTK技术及其工作原理，然后在点校正实验的基础上，重点介绍GPS—RTK的三种常规校正方法：单点校正，多点校正和参数校正的原理与对比实验，通过实验数据探讨了三种校正方法的精度。对比分析，认为多点校正和参数校正均优于单点校正。

Contrasting and analyzing on GPS-RTK Point correct means theory

Above all, this paper introduces GPS-RTK technique and its principle, points out that GPS-RTK technology adopting Real-Time Kinematic method is a great marker of GPS application. In contrast, to traditional measure technology, this technique enhances not only precision but also efficiency. Then introduces main contrast examination and principles on three GPS RTK correct means: single point correction, multi- points correction parameter correction and searches precision of three correction means by the examination which was on the basis of the point correction examination. During the parameter correction, this paper discusses parameter correction on the basis of Bursa model salvation seven parameter by the examination, variety correction contrasts and analyses. At last, draws a conclusion which both multi points correction and parameter correction take advantages over the point correction.
