Public information about the Global Positioning System (GPS) and other space-based positioning, navigation, and timing (PNT) systems.
The GPS is made up of three parts: satellites orbiting the Earth; control and monitoring stations on Earth; and the GPS receivers owned by users. GPS satellites broadcast signals from space that are picked up and identified by GPS receivers. Each GPS receiver then provides three-dimensional location (latitude, longitude, and altitude) plus the time.
Thank You USA
GPS is becoming an extremely useful tool. No wonder so many countries are using it, for many different purposes. In today's world it is almost essential.
The Internet, another ubiquitous tool, is also virtually indispensable.
As a citizen of a country, other than the USA, I am very thankful the the US government has made such tools available worldwide.

GPS and Internet
Like many other things, Americans pay for it and the whole world benefits. Although both were started for military purpose, the civilian impact on day to day life for people throughout the world is enormous.

was really cool! There's a lot to explore on that site. THANKS for sharing.

I am surprised that the government has not tried to tax the people for using the system! Of course the tax money did build the system in the first place.
Anyway it is an amazing system with great accuracy.

Shhhhhhhh
We are taxed enough. If they think of it, it will be taxed. Just don't tell anyone..

OK.....so where the heck am I?

It is taxed in that our taxes paid for it and maintain it.
GPS v. Internet
GPS? Yeah, I think we can say that comes from military applications.
The Internet? I don't think so. The various original intellectual nodes worked on military projects, but the interlinked communications that are the Net... that's more about the educational institutions coming together to gain access to each other more readily.
But that may be a biased perspective. I think you have to cut the cord, so to speak, at some point, when recognizing invention. Otherwise you might as well thank Alexander (Bell) for the net.

Taxing the Net, GPS, et.al.
In fact, they already do in a way I find totally acceptable.
Equipment manufacturers, sales outlets, internet providers, all are taxed on their profits. We pay part of that when buying access, buying equipment, buying new maps or traffic or using cell phones, fees to our ISPs.
That's not to say I don't half expect to see little "meters" someday popping up on my modem... or a miniature usage broadcaster someday popping up on my GPS...

That would be an incorrect statement. ARPANET was the first 'internet', and was developed by the military, for mil use only. Then, it gradually became what we know it as now.
