摘要
为实现无人机导航系统覆盖范围大、精度高、动态强等要求,从分析我国无人机导航现状入手,研究CNSS/GLONASS组合导航定位数据解算方法。基于"当前"统计模型建立状态方程和观测方程,并通过飞行实验和数据分析对相关性能进行验证。结果表明:提出的CNSS/GLONASS组合导航定位数据解算方法可实现2种系统的优势互补,提高北斗系统在无人机高动态导航中的可用性,增强无人导航精度。
For the realization of large coverage, high precision, dynamic requirements of UAV navigation system, this paper studies the data calculation method in CNSS/GLONASS integrated navigation and positioning from the status quo of UAV navigation. Based on the ＂current＂ statistical model, it establishes the state equation and observation equation, and verify the performance through flight experiment and data analysis. The result shows that the CNSS/GLONASS integrated navigation location data calculation method can realize complementary advantage of two systems, improve usability of Beidou satellite navigation system in UAV high dynamics navigation and enhance navigation accuracy.
