北斗卫星导航系统作为全球卫星导航系统之一,应用领域非常广泛,且具有重大意义。针对当前北斗卫星导航系统的导航效能评估方法缺乏问题,提出了一种基于地面卫星可见性和定位精度的导航效能评估方法。首先,通过分析典型空间环境、地面环境、导航终端要素,构建导航典型应用场景模型;然后,针对典型应用场景,利用地面可见性和定位精度,提出了导航定位效能评估方法;最后,通过仿真验证了所提方法的有效性。结果表明,该方法对典型场景下导航定位解算结果能准确地进行评估。

As one of the global satellite navigation systems, Beidou satellite navigation system is widely used in various fields and is of great significance. Aiming at the problem of the lack of navigation evaluation methods of the current Beidou satellite navigation system, a navigation evaluation method based on ground satellite visibility and positioning accuracy is proposed. First, by analyzing typical space environment, ground environment, and navigation terminal elements, typical navigation application scenario model is constructed. Then, for typical application scenarios, a navigation and positioning evaluation method is proposed using ground visibility and positioning accuracy. Finally, the effectiveness of the proposed method is verified by simulation experiments. The results show that the method can evaluate the results of navigation and positioning in typical scenarios.
