基于网络模式的北斗高精度定位数据播发

BeiDou High Precision Positioning Data Broadcasting Based on Network Mode

当前规模化大众应用对北斗高精度导航定位服务的需求日益增大。为此,设计系统解决北斗高精度定位数据处理与网络播发问题的关键技术流程。以四川省北斗地基增强系统为基础,结合消息队列技术设计并实现基于网络模式的北斗高精度定位数据播发系统,从而达到为海量用户提供实时动态的北斗民用高精度数据播发服务目的。测试结果表明,该定位系统平面精度小于0.7 m,高程精度小于1.5 m。

At present,the demand of large-scale public application to BeiDou high precision navigation and location service is increasing.To solve this problem,the key technology flow of BeiDou high precision positioning data processing and network broadcasting is proposed.Based on the foundation enhancement system of the BeiDou foundation of Sichuan province,the high precision positioning data broadcasting system based on the network mode is designed and realized by the message queuing technology,so as to provide real-time and dynamic high precision data broadcasting service for massive users.Test results show that,the positioning accuracy of the proposed positioning system is less than 0.7 m and the height accuracy is less than 1.5 m.
