Drew FitzGerald在访谈中指出,全球客机正越来越多地遭遇GPS欺骗攻击,这并非个例,飞行员几乎每天都在应对这种现象。GPS欺骗攻击与干扰攻击不同,欺骗攻击会向GPS系统注入虚假信息,而干扰攻击则会使GPS信号失效。近年来,GPS欺骗攻击事件激增,主要原因是廉价商用无人机的普及。GPS干扰和欺骗对飞行员的影响不同,干扰会使GPS失效,而欺骗则会向驾驶舱提供虚假信息,可能导致飞机误判危险。GPS欺骗攻击并非专门针对飞机,而是针对无人机,但飞机也受到了波及,其影响范围很广,难以完全避免。飞机和航电设备的差异使得应对GPS欺骗攻击的难度加大,增加了飞行员的工作负担,降低了飞行安全裕度。飞机起降阶段是飞行员工作强度最大的时期,也是GPS系统失效最危险的时期。航空公司和监管机构正在努力应对GPS欺骗攻击,但目前还没有针对恶意行为者的证据,主要担忧的是GPS欺骗技术可能被改进,并对飞机造成更大的威胁。解决GPS欺骗问题的方法之一是改进飞机上的GPS接收设备,但这种方法涉及到军事级技术,且实施起来较为复杂。GPS欺骗攻击的主要风险在于可能导致飞行员误判地面接近警告系统(GPWS)的警报,从而延误或错过采取必要措施的机会。由于GPS欺骗攻击的影响范围广,很难通过调整航线来完全避免,这与GPS系统本身的特性有关。 Lusia在访谈中主要起到引导和提问的作用,引导Drew FitzGerald阐述GPS欺骗技术对航空安全的影响,并就相关问题进行深入探讨。

Chapters
A commercial flight experiences a GPS spoofing incident, leading to a false alert and potential danger. This phenomenon is not isolated and affects hundreds of flights daily, especially in conflict zones.
  • GPS spoofing causes planes to receive false signals about their location.
  • Hundreds of flights daily are affected by fake GPS signals.
  • Pilots must adapt to these false alerts, which can be dangerous.

Shownotes Transcript

Anyone stuck in a knotted snarl of interstate clovers knows that GPS is both important and imperfect. But if GPS fails while you’re bringing a 737 in for a landing it could be catastrophic. 

Why is “GPS spoofing” on the rise—and how can airlines protect their flights against being caught up in conflict zones.

Guest: Drew FitzGerald), telecom reporter for the Wall Street Journal.
