摘　　要：针对目前北斗基准站网亚米级定位方法的不足,随着北斗系统的日益完善,提出一种基于基准站网的北斗单历元亚米级定位算法,分别进行了静态及车载动态两种条件下的实时测试。通过对定位结果统计发现,北斗及GPS系统在两种测试条件下外符合可以达到亚米级精度,GPS精度略优于北斗系统。In view of the shortcomings of the current Yami-level positioning method of the Beidou base station network,with the improvement of the Beidou system,a Beidou single-element sub-meter positioning algorithm based on the base station network is proposed,which respectively performs static and vehicle dynamics.Real-time testing under a variety of conditions.Through the statistics of the positioning results,it is found that the Beidou and GPS systems can meet the sub-meter accuracy under the two test conditions,and the GPS accuracy is slightly better than the Beidou system.
