适用于VRS的网络差分通讯协议分析

Communication Protocol Analysis for VRS Network Differential Positioning System

数据通讯是实现网络RTK的重要部分,本文介绍了虚拟参考站这种网络RTK技术所应用的通讯协议,并分析了这些通讯协议在网络RTK差分定位中的作用。通过自主研发的网络RTK软件Venus系统给出实例说明了服务器与客户端的对话过程,并利用试验分析了有线和无线网络延迟情况。

Communication protocol is very important to implement network RTK. This paper introduces the communication protocols in VRS technology and analyzes the use of each protocol. It shows the dialog process between server and client via the self-developed Venus, network RTK software system. The delay of communication is also tested in both the wire and the wireless conditions.
