摘　　要：多基准站就是在一定区域内建立多个基准站,对这片区域进行网状覆盖,这时基准站中的其中某一个当作基准,然后这个被当作基准的基准站进行计算和发播信息,基准站覆盖之后就能够更好的进行实时误差改正,这种技术就称为网络PTK技术。与常规PTK的技术相比,网络PTK定位结果更加准确,可靠性也会有一定的提高。网络PTK中的VRS技术是目前GPS定位技术上非常值得研究的方向。这篇文章主要是对VRS算法展开研究。首先对网络PTK技术的概念进行介绍,了解PTK系统的优点和应用,还详细介绍了VRS的概念以及定位原理,分析研究VRS系统中常用的几种内插方法,提出一点建议。A multi-base station is a net work of base sta ti ons set up in a cer tain area to cover the area.One of the base stations is used as the base st at ion,and t hen the base station is used to calculate and broadcast the information,when the base station is covered,it can make real-time error correction better.This technology is called network PTK technology.Compared with the conventional PTK technology,the network PTK positioning results are more accurate,and the reliability will be improved.VRS Technology in network PTK is the direction of current GPS positioning technology which is worth studying.This article is mainly on the VRS algorithm research.Firstly,the concept of network PTK technology is introduced,the merit and application of PTK system are understood,the concept and location principle of VRS are introduced in detail,several interpolation methods in common use in VRS system are analyzed and some suggestions are put forward.
