When we fire up our quad we look to see how many satellites its reading. It could be 10 maybe 12 or 15 and sometimes even more. It seems these signals can be received no matter where you are in the world. Does anyone ever wonder just how many satellites there are in this area around our globe. I mean are there thousands? Or just hundreds?. When you quad is reading 14 could it be that while your flying in New Hampshire that a few of the satellites are over the area of the Pacific? What powers these satellites. Do they have AAA or AA batteries. Maybe they are LIPO's! Hmmm maybe it is solar, that makes sense. How is it that the same satellites can monitor every single car with GPS in addition to all the other GPS dependant pieces of equipment. Doesn't it ever overheat? Is there actually any heat in outer space? My weird mind thinks about these things. Does anyone else think this too or am I the only crazy women or guy.
