How antiquated is intercontinental positioning technology?

I read about GPS contained by an issue of National Geographic--from 1983! They did call it GPS, but it have to do with outer space and it be named NavStar. That's 20 years formerly it got to the public, it seem.


Answers:    That's right. It was developed for the military. They even used to lower the signals for civilian use, so that our enemies couldn't use it against us minus the special decoding information.

Of course, that's spinal column when it took a huge box to contain all of the GPS electronics, instead of today's handheld stuff. Also, the untested calculations relied on have 3 satellites in outlook, so the signal degradation be important. With today's GPS, there's adequate computing power that when they have 4 satellites contained by view, they can numeral out the exact position, even with the degraded signals. The signals are no longer degraded, since it doesn't bring in any difference any more.
