The satellite navigation disruption is being caused by Russian trucks with jamming equipment meant to defend Russian troops from GPS-guided munitions, Benoit Roturier, satellite navigation head of France’s civil aviation authority DGAC, told Bloomberg.
“I don’t think the goal is to jam civil aviation at this stage,” he said. “That is collateral damage.”

On March 17, EASA published a safety information bulletin warning pilots that spoofing and/or jamming had intensified in the four geographical areas due to Russia’s invasion of Ukraine.
“The effects of [Global Navigation Satellite System] GNSS jamming and/or possible spoofing were observed by aircraft in various phases of their flights, in certain cases leading to rerouting or even to change the destination due to the inability to perform a safe landing procedure,” EASA said in a safety information bulletin.
“Under the present conditions, it is not possible to predict GNSS outages and their effects. The magnitude of the issues generated by such outage would depend upon the extent of the area concerned, on the duration and on the phase of flight of the affected aircraft.”

GPS signal interference along Finland’s eastern border with Russia.
The transportation agency said at the time it did not know what was causing the interference, which is difficult to detect on the ground or verify because of the relatively short durations of interference.
Fintraffic Air Navigation Services Ltd. issued a Notice to Air Missions (NOTAM) informing pilots of the issue and instructing them to use traditional approach systems that do not require a GPS signal for flying the final approach. Airlines were also told to make their own decisions about whether or not to fly in the region.
While the jamming can be a distraction for pilots, airlines have procedures in place for when GPS signals are lost. The ability to deal with such a disruption, however, can vary due to aircraft size. While some aircraft are able to use inertial reference system (IRS) to fix the airplane’s position as a workaround for GPS, it’s a system not common on smaller aircraft, according to Mentourpilot.com.
The jamming is a wake-up call, Roturier told Bloomberg.
Bring back the VOR, all is forgiven the NDB! Come back LORAN.
