Here is something to look into: global positioning satellites. Supposedly there are 24 of these orbiting the earth at 12,550 miles. They go around the earth twice a day. How in the fuck is something that is constantly moving, that far from earth, supposed to tell me where I’m at? I call bullshit. Word is, all global positioning systems are terrestrial based. That makes sense. There are transmitters and cell towers all over the planet that emit signals. Your receiver or phone is responsible for triangulation.
