It'd be more practical to have a faraday cage and several GPS transmitters to spoof a location (let's say 33.783, -118.14899); turn on the device, if it tells you it's located at 33.783, -118.14899, then it's GPS receiver is working correctly, anywhere else, then there's something wrong...
Reminds me of an anecdote that getting a rideshare in Moscow is difficult nowadays, because GPS for the whole city is jammed and the driver won't be able to find you.
- cenamus 1y agoProbably don't even need a cage, GPS signals are so weak you could probably overpower them with even the weakest jammer/transmitter
- antiframe 1y agoMy GPS location doesn't work in most buildings (with locating via WiFi turned off).
- IanCal 1y agoIs it easier to spoof GPS transmissions such that the phone will calculate it's at a specific coordinate? Rather than just check where they are reporting?
- ciupicri 1y agoI thought that Russians used GLONASS, not the GPS.
- xp84 1y agoIf they're worried about someone guiding missiles with satnav, they are probably jamming those both plus the European one, would be my guess, or since they control their own GLONASS system they could be encrypting it if it supports that, or shutting it down in those areas.
- namibj 1y agoThere are 4 major global coverage ones plus the JP one (QZSS) and iirc also some recent Indian. The major ones are GPS, Galileo, Glonass, Baidou.
