If your hand-held receiver only hears 2 GPS satellites, then it'll indicate
a location, but what it indicates won't be accurate or reliable.
GPS satellites do not 'find' anything, that is not their purpose.
Geostationary satellites are the ones used for GPS satellites.
GPS IIA-1 NAVSTAR 1 (Both GPS satellites)
GPS was not invented for forty years after WWII ended. GPS depends on satellites orbiting the earth. The satellites get there by rocket. The first satellite did not orbit the earth until 1957.
There are currently 30 healthy GPS satellites in orbit.
The Navigon GPS works internationally, like most other gps systems. They are run through satellites, which would not cease to work overseas in Europe or Asia.
GPS signals are processed in the GPS unit and displayed, and they are also processed via three Global Position Satellites. All four units work together and process GPS signals (some to the satellites from the GPS, and some from the satellites to the GPS) to create an accurate position.
A GPS works by satellites that are located in outer space. These satellites are connected with cameras that show the whole earth. You GPS and the satellites systems are working together to provide maps for you.
No. GPS Satellites are free to receive.
You can use a GPS anywhere the satellites shine.
No as GPS is obtained from satellites.
Smartphones use GPS receivers to receive signals from GPS satellites and determine their location. GPS receivers in smartphones work by triangulating the signals from at least four GPS satellites to calculate the phone's latitude, longitude, and altitude.
