摘要

目前,大多数飞机都使用全球卫星导航系统(gnss)进行导航。着陆是飞行的一个危险阶段,特别是当飞机无法清楚地看到机场跑道时。在这种情况下,在没有任何干扰的健康信号到达安装在飞机上的全球导航卫星系统接收天线的情况下,全球导航卫星系统对安全着陆是有用的。这表明在机场周围建立GNSS干扰定位安全网络的重要性。为接收干扰信号的GNSS天线点设计良好的配置对于干扰装置的成功定位至关重要。在这里,干扰信号到达这些点或锚节点(an)的时差被用作可观测值,并沿着阿兰达机场的跑道优化设计了一个具有四个an的安全网络,以减少网络的精度稀释(DOP)。我们的研究表明,通过这样的优化,最大DOP值可以减少50%,这意味着成功定位干扰设备的概率显著增加。

An optimal design of GNSS interference localisation wireless security network based on time-difference of arrivals for the Arlanda international airport
Abstract Today, most of the aircrafts are navigated by global navigation satellite systems (GNSSs). Landing is a dangerous phase of a flight especially when an airport runway is not clearly seen from the aircrafts. In such cases, GNSSs are useful for a safe landing under the circumstances that healthy signals, free of any interference, reach to GNSSs receiver antennas mounted on the aircrafts. This shows the importance of establishing GNSS interference localisation security networks around airports. Designing a good configuration for the points with GNSS antennas at for receiving interference signals is important for a successful localisation of the interference device. Here, the time-difference of the arrivals of an interference signal to such points or anchor nodes (ANs), are used as observables, and a security network with four ANs is optimally designed along the runways of the Arlanda airport to reduce the dilution of precision (DOP) of the network. Our study showed that by such an optimisation, the maximum DOP value can reduce by 50% meaning a significant increase in the probability of a successful interference device localisation.
