北斗接收机动态定位精度测试与分析

Dynamic Accuracy Testing and Analysis for BeiDou Receiver

随着北斗卫星导航系统建设和导航定位服务能力的发展,北斗卫星导航系统的多模芯片、天线、板块等关键技术已取得突破,掌握了自主知识产权,实现了产品化,国内目前已有北斗二代接收机研制成功。以差分GPS定位数据为真值,运用"跑车"测试法获取北斗接收机动态定位数据,通过与真值数据进行比对,获取北斗接收机动态定位误差数据,解算出动态定位精度,通过分析定位误差数据,可以为下一步提高接收机动态精度提供参考和依据。

With the construction and the development of the navigation and position capability of the BDS, breakthroughs of key technologies of BDS, such as muhichip, antenna and plate have been taken. Independent intellectual property rights were owned and commercialization was realized. At present, BeiDou receiver has been successfully developed. The BDS dynamic positioning data were obtained by using the GPS positioning data as true value and the ＂moving vehicle＂ testing method. The positioning error data of BeiDou receiver were got by comparison to true value, and the positioning accuracy was calculated. References can be offered to improve the dynamic position accuracy further through the analysis of the positioning error data.
