Another point is that civilian GPS chips are speed limited. Once the calculations prove the GPS is moving faster than the intended unit (like a car, or a civilian aircraft) the position updates start spreading out in time. Its hard baked into the CPU design, there isn't a software cheat around it. Its specifically to prevent someone from making a homemade, GPS guided munition from off the shelf parts.jabberwalkie09 said:AFAIK, Russisans do not use our GPS system natively. You can see what appears to be a Garmin unit above the instrumentation on that Fullback (SU-34). This isn't the first time that they have used commercial units in a theater. I want to say they've used them in Syria as well. We, the US, have restrictions on what can be exported. The commercial versions meet this requirement, but munitions type or units that can function with modification to munitions are controlled by the state department. An export license would be required.aggiehawg said:Can someone confirm this tweet? Is that what is pictured?wtmartinaggie said:
After this is all done, I wonder how much it comes out the the Russians got absolutely smoked on the Cyber battlefield.
There were unconfirmed reports of communications not working, jet navigation/HUD systems offline, and GPS calibration problems causing a great deal of chaos. It makes you wonder if rather than take it offline someone just tweaked things just enough for the russians to walk into a buzzsaw. It would also play into the phenomenon that continues to come out that the Ukrainians seem to be a step ahead of where the Russians will be and when...How much money was stolen from Russia’s military modernization campaign? This is as embarrassing as it is fascinating https://t.co/ZJTSgfhwr3

The Russians actually have a similar system named GLONASS but it isn't as accurate as our GPS system. They're working on trying to get it better though. I've put forth the reason that their cruise missile strikes have failed to achieve their objectives is because of the amount of error inherent in the Russian GLONASS. I want to say GPS has an error margin of about a foot where as GLONASS has about a 3 foot error in accuracy.
Edit: What I'm fuzzy on is whether we can deny civilian usage of the system specifically.
