I just dont see why this is so hard.
Every terminal needs access to the sky for it to communicate to the satelites.
Therefore it has access to GPS satellites too.
SpaceX satellites shouldnt allow a credential handshake without an encrypted GPS position which it checks against its geofencing database.
What am I missing?
- cute_boi 3y agogps can be spoofed? Chips can be reprogrammed? So, isn't it futile?
- alt227 3y agoBut (theoretically) the encryption of the handshake cant. As long as the hardware is designed correctly you can spoof as much GPS as you want, but you cant encrypt it so that SpaceX servers see it as valid.
- TheLoafOfBread 3y agoGPS sure can be spoofed, but then aren't you in a wrong cell and signal from satellite won't get to you, because it is pointing it's antenna on spoofed location?
- mapt 3y agoThe satellite link is comprised of bidirectional phased arrays. The satellite digitally points at an area of the ground to get reception just as the ground antenna digitally points at an area of sky. SpaceX knows exactly where its clients are, give or take ten kilometers, because that's how big its cell size is. No further telemetry is required. SpaceX is just reticent to comply with whatever authorities are leaning on it.
