A minimum of 24 operational Navstar satellites are required for the GPS system to work effectively. These satellites are strategically positioned in orbit to ensure global coverage and accurate positioning for GPS receivers on Earth.
GPS receivers do not 'use' elevation for anything. They use the signals from several satellites simultaneously to calculate the latitude, longitude, and elevation of the receiver's location. It takes a minimum of three satellites to calculate the latitude and longitude, a minimum of four satellites to calculate the latitude, longitude, and elevation, if more satellites can be found the latitude, longitude, and elevation calculations can be refined more accurately.

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 minimum of 4 satellites is needed to obtain a full GPS signal. These satellites are used to triangulate your position accurately on Earth.

The absolute minimum number is for momentary complete cover is 4 in a triangular prism shape, but these will not stay in the right positions as they are not in a geostationary orbit. 3 in geostationary orbit will give very bad and failing coverage at the poles and at the outer edge of their footprint 6, 3 in polar orbit and 3 in geostationary orbit will help, but for a practical coverage 4 in geostationary orbit and 4 in polar orbit will be more practical

The Global Positioning System (GPS) is based on trilateration, which requires a minimum of three satellite signals to determine a user's position in terms of latitude, longitude, and altitude. GPS uses time signals from at least four satellites to calculate accurate coordinates for a specific location.
A minimum of 4 satellites is needed to obtain a full GPS signal. These satellites are used to triangulate your position accurately on Earth.
