GPS is vulnerable to jamming—here’s how we might fix it

In September 2025, a Widerøe Airlines flight was trying to land in Vardø, Norway, which sits in the country’s far eastern arm, some 40 miles from the Russian coast. The cloud deck was low, and so was visibility. In such gray situations, pilots use GPS technology to help them land on a runway and not the side of a mountain.
