GPS signals are extremely weak, and they're necessarily received from omnidirectional antennas that can't provide much antenna gain. In some sense it's a miracle of signal processing that GPS can ever be received.

There have been developments in receiving antennas that are harder to jam.
Most jamming is horizontal and limited to a few bands. So by having a directional antenna and listening to all services for now it seems to work. But this is a cat and mouse game.
