摘要
甚高频全向信标(VOR)系统和测距仪(DME)系统是目前最常用的无线电导航系统,而VOR/DME导航和DME/DME导航更是区域导航(RNAV)系统推荐的方式。为满足区域导航所需导航性能要求,对区域导航系统的实际导航性能评估成为关键。在对无线电测量误差分析的基础上,对VOR/DME和DME/DME两种导航方式的实际导航性能评估方法进行了研究,并采用数字仿真对提出的方法进行验证。试验结果表明,提出的实际导航性能评估方法正确,能够有效跟踪实际导航误差,对于后续无线电区域导航技术在机载航空电子设备上的应用具有重要的参考价值。
VOR system and DME system are the most common radio navigation systems. And VOR/DME navigation and DME/DME navigation are the recommended methods of the RNAV system. In order to satisfy the required navigation performance of the RNAV system, how to evaluate the actual navigation performance of the area navigation system becomes a key technology. Based on the analysis of the radio measurement error character, the evaluation method of the actual navigation performance for VOR/DME navigation and DME/DME navigation is researched. Then, the simulation based on Matlab is carried out. The simulation result indicates that the evaluation method can characterize the actual navigation effectively. The result is of great significance to the radio area navigation technolo-v＇s further anolication in the airborne avionics
