摘要
首先介绍GPS RTK技术的局限性,然后分析基于GPS连续运行参考站网络虚拟参考站的基本原理、数学模型,根据综合误差线性内插原理计算虚拟参考站的综合原始观测数据,求出流动站的定位结果;然后就某市建立的虚拟参考站网络的实测数据进行动态、静态精度分析;最后得出结论:虚拟参考站技术扩大GPS RTK的使用范围,提高动态测量的精度,其开放式的数据服务使VRS技术成为NetWork RTK的主要发展方向之一.
Abstract
The paper first introduces the limitation of GPS RTK technology and analyzes the basic principle and mathematics model of Virtual Reference Station based on GPS continuously operating reference station. It figures out the positioning result of rove station according to the integrative raw observation data of the VRS got by total error linear interpolation method. And then,it makes dynamic and static accuracy analysis on actual measured data from the VRS built in a certain city. At last,it draws a conclusion that the VRS technology expands the application range of GPS RTK and improves the accuracy of dynamic measurement. And its open data service make VRS technology become one of main developing directions of Network RTK.
