GPS Jammed at NATO exercise

SS,

We can retaliate by jamming their systems as well.

Pete,

Radar is not self contained. It fires radio waves outside itself and listens for returns. Anything can absorb or deflect these signals externally and the unit gets no returns. That how stealth systems work.

There are several navigation methods besides GPS that are still perfectly valid. It is just everyone likes technology. Despite the adage that the more complicated they make something the more likely it is to fail.
