The GPS satellites aren't receiving anything. The GPS satellites transmit signals, and the starlink terminals (and other users of GPS) receive those signals.

Wellll you could technically jam their uplink channels, but doing so may get the US in your doorstep quite quickly

This is a great plot for a B movie or a trashy military action book. “The bad guys are jamming GPS uplink and we only have two weeks until the almanacs are out of date and the whole system breaks down. Millions of innocent Americans will drive into rivers by accident.”

More to the point, to do that to this number of satellites on this big an area you'd need nuclear power plant levels of power, and it would only degrade GPS a bit (their clocks slowly desync when uplink is blocked)

Ok they said the GPS of the starlink satellites is being jammed, and the question was how. The comment I was replying to did not say the terminal, it said the satellite. Maybe that's the confusion

Maybe he's implying they're literally cancelling out the waves like ANC headphones but with emf and a large geographic area.
