Globle positioning system
how many satellites present in the space
vector GIS, Raster GIS, Hybrid GIS
GPS satellites do not 'find' anything, that is not their purpose.
At leAst 3
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.
a GPS device will need at least 3 satellite locks to work.
GIS (Geographic Information Systems) is tool to display and analyze information geographically. GPS (Global Positioning Systems) is a technology that uses satellites to give one its position on the Earth with the aid of a GPS device or unit. GPS can be incorporated into GIS by using a GPS device to collect points, lines, or polygons, which can be imported into a GIS application for future analysis and interpretation.

There are currently 30 healthy GPS satellites in orbit.

Geostationary satellites are the ones used for GPS satellites.
Currently 31 in both GPS and GLONASS (Russian navigation system, similar to GPS)
24 active with 6 spares.
