摘要
航路飞行阶段的导航台选择是区域导航(area navigation,RNAV)运行的主要环节。在RNAV选台过程中通常会遇到换台频繁或台站跳变问题。根据测距机(distance measure equipment,DME)/DME导航方式提出了实际导航性能(actual navigation performance,ANP)的计算方法,并通过设定ANP阈值结合最小ANP值的方法设计航路飞行阶段DME台站选择算法。对京沪航线及其周围的DME台站数据进行了仿真实验,结果表明,该选台算法在满足导航精度要求的情况下有效避免了换台频繁和台站跳变问题。
The navigation station selection is a major aspect of the area navigation(RNAV) in en-route phase of flight. The common problems are the frequent station switching and the navigation station hopping in RNAV station selection. Actual navigation performance(ANP) calculation is presented by the distance measure equipment(DME)/DME navigation way, and a DME station selection algorithm is designed by setting the ANPthreshold combining with the least ANP in en-route phase of flight. Some simulation experiments are performed using the data about Beijing Shanghai route and its surrounding DME stations. The results show that the station selection algorithm meets the requirements of navigation accuracy while effectively avoiding the frequent station switching and the navigation station hopping.
