摘要
北斗一代用户机的定位精度与其所在地理位置紧密相关,在实际使用和测试的过程中,用户更加关心的是在不同情况下东北天坐标系下的定位精度。在对北斗一代导航定位系统工作原理及其定位误差来源分析的基础上,建立了东北天坐标系下的北斗一代用户机定位精度模型,重点对无标校平坦地区、无标校起伏地区和有标校平坦地区和有标校起伏地区4种情况下的定位精度进行了仿真分析并给出了使用建议。
The position accuracy of CNSS1 receiver is closely related to its geo-location. In practical operation and test,the user is rather concerned about the position accuracy based on NEU coordinates under different conditions. By analyzing the principle and error source of CNSS1 ,a position accuracy model for CNSS1 receiver is established based on NEU coordinates. The position accuracies in fiat area with and without calibration and in rugged area with and without calibration are simulated and analyzed. Usage recommendations are also provided.
