A 63-hour-long marathon of GPS jamming attacks disrupted global satellite navigation systems for hundreds of aircraft flying through the Baltic region – and Russia is thought to be responsible
Russia is suspected of launching a record-breaking 63-hour-long attack on GPS signals in the Baltic region. The incident, which affected hundreds of passenger jets earlier this month, occurred amid rising tensions between Russia and the NATO military alliance more than two years since the start of Russia’s full-scale invasion of Ukraine.
“We have seen an increase in GPS jamming since the start of Russia’s war against Ukraine, and allies have publicly warned that Russia has been behind GPS jamming affecting aviation and shipping,” a NATO official told New Scientist. “Russia has a track record of jamming GPS signals and has a range of capabilities for electronic warfare.”
That device is called a CRPA (pronounced serpa). They are very effective at anti-jam.
As far as VOR jamming, those use a VHF omni-directional antenna, so it can be jammed. It might be hard because of the omni-directional part and the numbers of them, but definitely doable.
Might have to break out the ole INS
Inertial systems are good enough for rockets going to Mars, so why not a plane flying in a straight line?
So I read about it on Wikipedia and apparently they’re still the main navigation tool for modern airliners. GPS is just used to maintain the accuracy of the INS.
They are used for planes. The problem is the usable ones are stupidly expensive and/or classified millitary hardware.
