| 摘 要： | 北斗卫星导航系统已具有区域无源导航能力,为了研究当前可用星座情况下的系统定位精度,首先分析用户等效测距误差(UERE)结合精度因子(DOP)值的精度评估方法计算模型,然后利用上述方法采用实际数据对比分析了北斗卫星导航系统和GPS系统一段时间内的静态定位精度。通过分析得出,在该段时间内北斗系统定位精度在水平方向上误差优于5 m,在高程方向上误差优于15 m。

| Abstract: | Beidou satellite navigation system has possessed a regional passive navigation capability. In order to study the po-sitioning accuracy of Beidou system in the case of currently available constellations,the calculation model of the user equivalent range error（UERE）and accuracy assessment method combining dilution of precision（DOP）value is analyzed in this paper. By using the above method and the actual data,the static positioning accuracy in a period of time of Beidou system and GPS sys-tem is compared and analyzed. The analysis result indicates that,during this period,Beidou system positioning accuracy error is less than 5 m in the horizontal direction and 15 m in height direction. |
