It might be possible for e.g. airliners to use military GPS with anti-spoofing (encrypted GPS signal which is harder to spoof or jam, but which needs special receivers that have to be rekeyed regularly). Obvs that would require some bureaucratic cooperation between the air carriers and the military. Also, at least near airports, ground beacons can be used the same way.

Obviously the stuff with maps and triangulation, or celestial navigation can be done by computer now, instead of by some crewmember with a calculator. But GPS is sure a lot simpler to use.

Spoofing GPS, GLONASS, Galileo, and the Chinese system (I forget what it's called) all at the same time might be much more difficult than spoofing just one.

Isnt GPS and other signal blocking against ITU? Seems like a slippery slope into being sanctioned further

This sounds legitimately annoying... But why is this canceling flights? Do the pilots not carry maps? Plus, they're in the air, can't they rely on radar guidance? They may have radar on the aircraft, but there's definitely ground based radar as well.

Pilots are very well trained, they should be able to handle this... What did pilots do in 1970, before gps existed?

Per Kagi's summary tool:

There has been a significant increase in GPS/GNSS jamming and spoofing attacks, particularly in the Baltic region and around Ukraine and the Middle East.

The attacks have disrupted air and maritime navigation, with thousands of planes reporting issues with their GPS systems in the Baltic region.

Russia has been increasingly blamed as the source of these GPS attacks, with signals traced back to Russian regions like Kaliningrad.

The attacks can either jam GPS signals entirely, making the systems unusable, or spoof the signals to show false locations.

The disruptions have led to flight cancellations and aborted landings, raising concerns about the potential for major accidents and environmental disasters.

Governments and aviation/maritime safety experts are increasingly sounding the alarm about the threat posed by these GPS attacks.

The attacks may be a form of "hybrid warfare" aimed at creating uncertainty and disrupting civilian and commercial activities.

The number of GPS jamming and spoofing incidents has increased significantly over the past 4 years globally.

While the disruptions have mostly impacted high-altitude planes and ships, there are concerns about the potential to impact individual GPS-reliant systems in the future.

Technical countermeasures are being explored to reduce the impact of these GPS attacks, but the threat is expected to continue growing.
