But to move forward, without people monitoring satellites, it wouldn't take long for them to drft out of orbit. Now I am not saying it would be drastic, but even a matter of a few feet offcourse in the sky could lead to the directions being miles off on your GPS. One satellite just a bit out of orbit would make it completely and utterly useless. If you want to risk that, then alright. I might not be the greatest expert on technology ever, but this much I know from talking with a professional about. Come a global emergency where no one is regulating courses, you'd be better off with a paper map.
What you have, essentially, is a very fancy map with no tracking function. Useful if you have no other map, but not really worth using.
A GPS does not connect to the internet. Because it is essentially a passive tracking device (meaning that only a GPS can initiate being 'tracked', so as to protect your privacy), it has to receive signals from a satellite.
That was in the post you quoted, and you essentially repeated it like you didn't see what I wrote. The reason why I replied to you about the towers wasn't because I was arguing anything about satellites (as I mentioned before, I know nothing about them) but because you mentioned internet. I'm a computer science major and a complete geek. My curriculum doesn't really cover network infrastructure, but I have taking networking classes before and I know the basics. I replied because you said connecting to the internet requires some sort of tower, which I know not to be true.
