IATA Reports 500% Spike In GPS Spoofing Last Year

https://simpleflying.com/iata-500-spike-gps-spoofing-last-year/ https://www.iata.org/en/publications/safety-report/executive-summary/ -- report available here in full The International Air Transport Association (IATA) has issued its 2024 safety report, highlighting that the number of incidents increased year-over-year (YoY), yet pleaded not to draw incorrect statistical conclusions from individual events. According to IATA, in 2024, the aviation industry successfully transported 5 billion passengers on over 40 million flights. While the long-term trend showed that the industry has significantly reduced the number of accidents, with 1.13 accidents per million sectors in 2024 compared to 3.72 per million sectors in 2005, the number of accidents in 2024 increased YoY. “Although the number of accidents increased in 2024, it is important not to draw incorrect statistical conclusions from individual events, as aviation remains one of the safest modes of transport.” ... One of the noteworthy points that IATA made in its release was that Global Navigation Satellite System (GNSS)-related interference increased sharply in 2024 compared to 2023. “While there are several back-up systems in place to support aviation safety even when these systems are affected, these incidents still pose deliberate and unacceptable risks to civil aviation. GNSS interference is most prevalent in Türkiye, Iraq, and Egypt.” FWIW. Sharing out of interest on the matter. Regards

Bink63 The highest AM frequency wattage licensed to stations is 50,000 watts.

I'm not sure if you mean NDB for that 50,000 watts, but there are some commercial AM radio stations with 2 MW of power.

I didn't write the post I quoted.

A commercial AM Radio Station in the U.S. can only be licensed for a max of 50 KW ERP.

There's a common term for AM Stations broadcasting at an ERP of 50 KW, "Blowtorch".

I used to be able to clearly receive WLS-AM 890, Chicago illannoys, in Middle Park Colorado, at night.

I'll use Winter Park, CO as a specific locale for reception...

given the distance from WLS-AM's Broadcast Towers in Tinley Park IL, curvature of the Earth and some VERY TALL Mountains between Winter Park, CO and Tinley Park, IL, those Clear Channel Stations are called "Blowtorches" for good reason.

Not quite sure where your getting you knowledge, or flawed info from, but a commercial AM Radio Station is, in fact, a Non Directional Beacon (NDB) for Aviation Navigation purposes.

Now, non-voice NDBs specifically for navigation use, are limited to 300 Watts ERP.

ETA: Just got off a call with a close friend who has an extensive Broadcast Radio background and they got a chuckle out of your post. As soon as I mentioned "Blowtorch", they went off into a much more technical humorous rant on those stations, than I posted here.

real_aurgathor The moon also works but the method (literally called the Lunar Method) requires observations, comulation and consulting with published almach. Computers can deal with the latter two, and electromechanical devices can cover the issue of observations but so far no one has bothered to build such a machine. Much of the world is entirely depending on GPS (spefifically the US variant alone), that is a lot of eggs, in one basket.

And over-reliance on a single system is a major issue. The lowest hanging fruit would be to simultaneously monitor all four, and discard the one that disagrees with the others. That should take care of the single system spoofing. However, some dedicated actor may spoof 3 of the 4, so in that case the system would need to rely on other more involved measurements and algorithms, but given the low cost of computing power, that should be easily doable om airplanes or ships where a little extra weight shouldn't make much of a difference.

Navigation existed well before the advent of GPS, so one can just incorporate some of those older methods.

Blackbird Sure, built before GPS existed, and pretty costly to make in their heyday. With mems tech and other advances they can be made cheaper but again does boeing or airbus sell a plane that has an internal nav system certified with a certain accuracy?

real_aurgathor Spefifically for aircraft it has to be done such that the crew isn't burrended down with yet some other process that becomes a distraction. On the other hand a little bit of busy work keeps them focused too so you end up automating most of it and have the crew perform some sort of check, comparison.
