Some telecommunication companies have paid and others were paid for by governments.
The GPS system was developed and funded by the U.S. Department of Defense. The cost of putting GPS satellites into orbit was covered by the U.S. government.
Polar orbit
Saturn V rockets, the most powerful engines ever built, lifted all of the Apollo missions from Earth's surface into orbit.
Garmin eTrex is a line of GPS's put out by Garmin.
No.
There are at least 24 GPS satellites in operation at any given time with a number of on-orbit spares in case one fails. Each one is in a 12 hour orbit (meaning it takes 12 hours to orbit the earth). They are in a variety of six different orbits and are not just locked into a geosynchronous orbit (meaning they stay over roughly the same place on earth at all times, like your satellite TV and communications satellites) like some satellites.All GPS satellites are owned and operated by the US Air Force and are controlled specifically by the 2d Space Operations Squadron at Schriever AFB in Colorado Springs, CO. There is not an easy way to deny the GPS capability to our enemies without also denying our own capability, so it is a free system open to anyone that has the technology to utilize it.GPS satellites carry not only positional data but also extremely precise timing signals, which help the GPS receivers on the ground to triangulate their position and are even used to validate and secure financial transactions, etc. When the system was first created, artificial timing errors were put into the signal to try to reduce the effectiveness of the system for non-military users, but it was removed in 2000.The GPS satellites also have NUDET (Nuclear Detonation) sensors on them to detect nuclear detonations almost anywhere on earth.To use GPS you need to be in clear view of at the very least 3 satellites but you should be in view of 6 satellites at any given time unless some are blocked by objects, mountains, etc. So, GPS usually doesn't work well in-doors or even in a forrest or valley at times.
No, there was no GPS in 1918. Neither the concepts on which GPS operates had occurred to anyone nor was the primitive electronics of the time able to support its requirements had anyone thought of it. Also in 1918 it was not possible to put satellites in orbit.The first satellite put in orbit was in 1957.The concepts on which GPS operates were not worked out until the late 1960s.The first launch of a GPS satellite was on February 1978; 39 years ago.The GPS requires 24 operating satellites and 6 functional spare satellites in orbit to operate.Early GPS receivers (available only to the military and large companies) cost tens of thousands of dollars and weighed from 20 to 100 pounds. This was all that was available until the very late 1980s.
Learning how to use a GPS is easy. All you have to do is put in the address you are wanting to go to and go.
All kind of people can use the GPS. Sailors,people on the streets, and truck drivers. So There are different people who put GPS to Use.
GPS Chips are put into Mobile Phones, PDA's, and SatNavs.
Put a device like GPS is absolutely fine to put into your luggage.
Once you've put the GPS stand (or car dock) on the windshield or the pad put the lever down on the GPS stand.
It's the cost of it, it costs too much.
You can't put music on a GPS. It isn't an MP3 player.
Polar orbit
The word Moon is a name given to the natural satellite in orbit around the Earth. We attribute this name to most objects large enough to see in orbit around other planets. In this way Moons and Natural Satellites are one in the same. Artifical Satellites are what we put into orbit around the earth IE GPS Satellites, but are man made.

The options that are available on Garmin GPS watch is you can have your own gps, and you can download music on it and you can also put games on your gps whenever you get bored.
