Strict security for set-top boxes

Yeah, but you need at least three satellites (even with low signal) to triangulate the signal to an area. If I'm driving at 120km/h and I have a connection to 12 satellites, I can only triangulate to a radius of 20-30m....

20-30 meters? my garmin with it's little dash aerial i get on average 4-6meters doing 120 even without it's external aerial i get way better than 20 meters.

ps. 3meter radius accuracy is the best for civilian
