摘　　要：针对利用陆基无线电导航系统实施区域导航运行时需要自动选择合理的导航台进行精确定位的要求,提出了一种陆基无线电导航系统自动选台和定位算法,并且采用上海虹桥机场到北京首都机场的RNAV航路和导航台信息进行了仿真实验,实验表明,提出的陆基无线电导航系统自动选台和定位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同时能避免导航台切换过于频繁,最终实现飞机的精确定位,确保DME/DME定位满足RNAV 2、VOR/DME定位满足RNAV 5的导航性能要求。Ground-based radio navigation RNAV needs to select reasonable station and accuracy position, therefore a ground-based radio navigation automatic station selection and location algorithm is proposed in this paper. Based on the information of navaid stations and RNAV airways in the area of ZSSS and ZBAA, some simulation experiments are performed. The simulation results show that the algorithm selects acceptable and better stations while avoiding unnecessarily frequent station switching, and realize the location of airplane. The performance of DME/DME location can satisfy RNAV 2, and VOR/DME can satisfy RNAV 5.
