Satellite reveals immense scale of GPS signal tampering

GPS tampering “data” from a company who’s upcoming tech is advertised to solve the problem their data shows is indeed a problem, and coincidentally also raised their 170M series C

> Gunning says that, with the superior strength of the PNT signal transmitted by the company's planned LEO constellation, existing jammers would only be able to affect about 5% of the area they can currently disrupt. "The effect of the jamming is going to be reduced to a smaller radius," Gunning said. "The degradation area will go down, and the full lock-out radius will also go down."

Will this suddenly make offending countries scramble for an alternative?

I think by “fly”, they mean several hundred km in the air where you have sharply reduced below-the-horizon blocking.

Anyone got any leads on Doppler shift detecting equipment? Not hard to detect you’re getting spoofed or jammed with based on that. Power levels being all improbable wouldn’t be hard to detect either. Difficult to detect if “tuned” to a particular target but blanket spoofing would be hard.

Then at the consumer level, fallback options exist (hi wifi); but having something more local would be nice. FM radio stations maybe? Can mess with those too ofc. AM systems are already a fallback in aviation for gross navigation.

A private GNSS constellation has very business cases.

Is GNSS jamming really as bad a problem as the article makes it seem?

The article itself reads like guerilla advertising so I'm inclined not to take it at face value.

The worst ad ridden website I’ve ever seen.

I honestly see this jamming as a win. GNSS is a global blanket opt-in American spyware.
