I just learned from a meeting with radio astronomers that AST SpaceMobile is already disrupting GPS signals with only a handful of direct-to-device satellites in orbit.

(And I should add that I don't know the degree of disruption, but ummmm a lot of people are extremely dependent on GPS for lots of extremely important things, so any disruption at all seems like someone in a government somewhere should be angry. Not just radio astronomers.)
Oh, so that's what's disrupting the GPS/GNSS that modern aviation relies on.
You'll see frequent reports on the ACARS bots on the Fediverse, for example:

@sundogplanets The problem is that spectrum use is by consensus and when one rogue states pretty issues licences that have global impact we're stuffed.
If the US wants to mess up coordination in its own territory then so be it, but these clowns are messing up HF and satcom with global impact. And when US licences operators don't behave outside of the US the FCC says "too bad".
AST stomping on amateur bands too. https://www.openresearch.institute/2025/09/12/defending-amateur-radio-spectrum-the-ast-spacemobile-battle-continues/

Fortunately, I never subscribed to this 'feature becomes dependency' problem.
Unfortunately, my Govrrnment drank the koolaid.

@sundogplanets
Is that a bug or is it a feature, for possible use when needed? -

@sundogplanets
Or AST could be testing their GPS capability for the DoW.https://cysat.eu/news/ast-spacemobile-gps-backup-pnt-defense

@sundogplanets any details you can share about the technical specifics?

@zl2tod @sundogplanets No, I don't see any indication that AST satellites are affecting aircraft GNSS. The GPS/GNSS disruption is almost entirely intentional jamming in conflict zones, or Russia jamming European countries. See my site, https://gpsjam.org.
I haven't seen any indication of AST causing interference with GPS (yet) or anyone else talking about them currently causing interference.

@sundogplanets oh, the Space Force isn’t going to like that at all. GPS is critical war-fighting infrastructure first, everything else second.

@sundogplanets Our best and brightest experts are on the job now.
