摘　　要：针对利用陆基无线电导航系统实施区域导航(RNAV)运行时需要自动选择合理的导航台进行导航的要求,提出了一种考虑多因素的陆基无线电自动选台算法,并且采用两机场间的RNAV航路和周围DME导航台的信息,对RNAV航路阶段设计的考虑多因素的自动选台算法与考虑单一因素的选台算法结果进行对比和分析,并对所选的DME/DME区域导航精度进行验证。实验表明,提出的考虑多因素的陆基无线电自动选台算法可有效地选择较好的导航台,在及时切换为更好的导航台的同时能避免导航台切换频繁,最终实现飞机的精确定位,满足DME/DME区域导航性能要求。For the implementation of RNAV operation by using ground-based radio navigation system needs to select a reasonable station for navigation, a ground-based radio automatic station selection algorithm is proposed with multiple factors into consideration. Based on the information of RNAV airways and DME stations around between ZSSS and ZBAA, a comparative analysis is made of the automatic station selection algorithm considering multiple factors for RNAV airway design with the algorithm only considering a single factor, and the precision of selected DME / DME RNAV is verified. The experimental results show that the proposed multi-factor ground-based radio automatic station selection algorithm can effectively select better stations, avoid frequent switching of stations while switching to a better station in time, as well as ultimately achieving precise positioning of the aircraft, and satisfying the requirements of DME / DME RNAV performance.
