how many satellites present in the space
Globle positioning system
GPS satellites do not 'find' anything, that is not their purpose.
There are currently 32 GPS satellites Orbiting earth at 20,000Kms above sea level There are also 24 GLONASS satellites (The russian version of a GPS satellite) Which many high end GPS receivers will use in conjunction with the standard GPS satellites. These orbit a little lower than GPS at arond 19,000Kms above sea level. There are 4 Galileo Satellites, which are currently un used, but are the start of the European satellite constealltion which is a work in progress. They orbit at 24,000Kms above sea level. On top of all that, there are 10 Chinese navigation satellites called COMPASS orbiting in an orbit above China and Asia. They orbit at around 21,000 Kms above sea level.

There are currently 30 healthy GPS satellites in orbit.

The Nextel GPS tracking system acquires its signal by searching for satellites that are in the sky in the area and by calculating the user's position based on those satellites.
Globle positioning system
As long as you can see the sky, the GPS satellites can see you. So to 'block' the GPS satellites from "seeing" you, get under something like an overpass or deciduous trees. Flat up against the north or south side of a building helps.
GPS satellites do not 'find' anything, that is not their purpose.
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.
