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.
For legal reasons I base this off of nothing but just turn your jammer to the sky. Could get fancy and point out directly at the satellites since my understanding is it's pretty easy to know where they are.
Edit to add: I do not mean the GPS satellites or the starlink ground terminals. That was not the question so that is not my answer. I mean the starlink satellites
That doesn't work. GPS is broadcast, not bidirectional communication, so preventing the satellites from seeing the GPS receiver does nothing: they're not looking to begin with.
What are you talking about? The jammers are on the ground. Just like receivers on the ground can be jammed with bad RF nearby, so can receivers in space. You just point the bad RF towards the receiver

Ok that makes a lot of sense, thank you.
