There's also a symmetry concern. All parties to any conflict would be using something like GPS. But if only one has access to SBS, the others have less to lose

There's also a symmetry concern. All parties to any conflict would be using something like GPS. But if only one has access to SBS, the others have less to lose by taking the fight into space.

Of course, a country that can shoot down a satellite can probably already launch a nuke, if they have one. And they likely have a bunch of stuff in space as well. There are a few counterexamples, but they wouldn't be, for instance, Russia or China or the US. They'd be mad to do that over a power delivery system that they can utilize or hack.

The US Military can degrade GPS performance of a selected area while keeping the military encrypted accuracy at standard levels which they did during the Kargil War IIRC.
