虚拟RINEX技术在城市勘测中的应用

The Application of Virtual RINEX Technique in Urban Exploratory Survey

连续运行卫星定位系统(CORS)能够实时、快速、高精度获取空间数据的3维定位结果,在通讯条件受限、GPS动态定位技术无法应用的情况下,使用虚拟RINEX动态测量数据后处理PPK(PostProcessing Kinematic)技术可以弥补网络RTK的不足,提高作业效率。本文介绍了虚拟RINEX PPK技术的原理及其在实际勘测工作中的应用。

The CORS can acquire real-time 3D spatial positioning data with speed and accuracy.Under the condition of restricted communication and inability to apply GPS dynamic positioning technique,applying virtual RINEX dynamic surveying data PPK technique can make up for the shortcomings of network RTK and improve operation efficiency.This paper introduces the principle of virtual RINEX PPK technique and its application in exploratory survey practice.
