Ops.group published a report on GPS spoofing back in 2024.[1] It's bad. Ops.group is an organization for dispatchers and pilots, the people who decide the routes aircraft take and fly them. They are really angry about it. Key concerns: - The greatest safety concern is the degraded functionality of the Ground Proximity Warning System (GPWS). The system does not operate correctly after spoofing, even if GPS coverage is…

> spoofing I don't understand how "spoof-to" works. If you have to mimic a satellite then isn't everyone going to get a different location? Unless you're tracking a specific target how can you intentionally spoof them to a desired location? I'd assume the best you could do is create a fixed offset. > The military wants to go mostly inertial and is working on better inertial systems. Given the drift rate this is an id…

The worst ad ridden website I’ve ever seen.

It’s jammed!

Your satellite doesn't want to be sending out lots of different signals - due to a limited power budget. So you have to send out one (or maybe a couple) of signals protected by a key. Yes, you can distribute that key individually to clients using public key cryptography over the same link (and many services like pay TV do exactly that). But fundamentally any client who is able to decrypt the main stream can also shar…

> jam the same stream. To add to that, other people won't be able to spoof the original stream (as that needs the private key), but instead only jam it. It would be the same failure mode as SSL certificates.

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.

I also read the same guerilla advertising for an alternative between the lines. If I understood it correctly from the article, the alternative itself is basically more of the same, but with a stronger signal. So they basically will launch 300 satellites with an alternative that will face the exact same issues once jamming output signals increase too?

And 99.99% of those GNSS receivers are connected to the internet. Or are in proximity to an (American controlled/designed) internet connected device.

This sounds like you have an issue with internet connected devices.
