I guess you could say that it all started in 1972. The United States Air Force Central Inertial Guidance Test Facility or as I like to call it, the USAFCIGTF experimented with two GPS prototypes in flight tests, using ground based pseudo satellites over White Sands Missile Range, or as I like to call it, the WSMR.

WWII US Gato class subs could be built in 9 months.

No, GPS doesn't work outside the US.
The ''GPS'' lets us locate a point you want to go to, the gives us directions on the way there.
Not sure which company actually built the first GPS hardware, but the GPS system was first developed for, and used by, the US Military (US Department of Defense) in 1973.
Us dod
To navigate around ones own surroundings and to locate objects equipped with GPS. Find and Seek is what GPS does for us.
GPS was created by the Pentagon and is currently operated by the US Department of Defense.
GPS satellites are owned by the United States government. The US Department of Defense (DOD) is responsible for GPS operations and management.
Unfortunately GPS systems are expensive. You will not find a GPS system for under $150.00 US Dollars. You will get a nice product that will last long if you invest money into it.
