Next time you’re on a flight, download a GPS speedometer app and launch it right before takeoff. You’ll notice that it’ll accurately measure the plane’s speed up to around 500 MPH, before it suddenly stops giving you a speed readout.
Like the other person said, this is to prevent your average dude building a guided missile using an old phone they have lying around.
Probably would just use an IMU exactly as the plane itself already does for its own navigation.
They get a lock on the ground, synchronize the IMU with the Earth’s orbit, and they keep track of where they’ve moved from the origin, supplemented by GPS.
That makes sense! Thanks
