For some reason I thought block 3 gps has some kind of rotating side channel bit selection method to resist jamming “perform more consistently in poor electromagnetic conditions” or some such…
would work if it’s regular EM interference but when a satellite broadcasts across an entire spectrum of frequencies there’s little more you can do to adapt.
I mean in a more technical sense. In what way is “traditional” terrestrial frequency jamming with wide band noise different when the source is extraterrestrial instead?
I have enough limited experience receiving and transmitting rf signals between terrestrial stations and between terrestrial and extraterrestrial stations that I’m very interested in how rf interference and therefore its mitigation is different when the interference source is extraterrestrial.
Oh no, not something to push people to adopt new block 3 capable receivers!
Surely they won’t just use $20 glonass or beidou receivers…
They’re all susceptible to the same attack. It’s “just” jamming.

How would you say that interference broadcast from satellite is different?
EM interference is going to hit lots of places across the spectrum and turn it into swiss cheese.
a satellite actively vomiting EM interference within a radio band takes away the cheese and tells you to fuck off.
