24 active with 6 spares.
There are currently 30 healthy GPS satellites in orbit.
GPS satellites do not 'find' anything, that is not their purpose.
Geostationary satellites are the ones used for GPS satellites.
A minimum of 4 satellites is needed to obtain a full GPS signal. These satellites are used to triangulate your position accurately on Earth.
Currently 31 in both GPS and GLONASS (Russian navigation system, similar to GPS)
32
GPS IIA-1 NAVSTAR 1 (Both GPS satellites)
Every GPS unit needs a minimum of four (4) satellites to compute a 3-dimensional position, and performs more accurate calculations with more satellites. I think my TomTom is capable of using 12 simultaneous satellites if it can see that many. Yours may be different.
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.
