中文摘要: 卫星导航系统是民航飞机导航的主要手段之一。因高高原机场环境复杂多变,单一GPS导航系统难以满足现实需求。基于GPS/BDS双模导航能显著提高导航性能,具有明显优势。但这将带来大的卫星冗余,增加了计算量的同时会引入更多低导航质量的卫星。为此,本文针对高高原机场情况,提出一种基于卫星仰角和方位角的快速选星算法,可以减少计算负担,同时自动选出高质量卫星信号,满足实际的导航需求。最后,选取四个典型的高高原机场场景对算法进行了充分的仿真实验分析。仿真结果验证了本文所提方法的有效性。
Abstract:Satellite navigation is one of the main means of airliner navigation. In response to the complex and variable environment of high altitude airports, a single GPS navigation system struggles to meet real-world demands. Utilizing GPS/BDS dual-mode navigation can significantly enhance navigation performance and offer clear advantages. But this will bring about significant satellite redundancy, increase computational complexity, and introduce more satellites with low navigation quality. Therefore, this article proposes a fast star selection algorithm based on the satellite elevation and azimuth angles for high altitude airports, reducing the computational burden and automatically selecting high-quality satellite signals to meet practical navigation needs. Finally, four typical high-altitude airport scenarios are selected for sufficient simulation and experimental analysis of the algorithm. Simulation results confirm the effectiveness of the proposed algorithm.
