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.

The network of satellites operated and maintained by the USA is the Global Positioning System (GPS). There are other systems, comprised of other constellations of satellites, and operated and maintained by other countries.
Everywhere. Latitude and longitude are systems of measurement on the physical Earth; using two coordinates, we can define any location on the surface of the Earth. They don't have any physical existence.
It's all down to timing ! Ground stations 'decode' the amount of time it takes for a signal to 'bounce' from the satellite to the Earth. This pinpoints the location of each GPS satellite - and thus the necessary calculations produce the coordinates
GPS or Global Positioning Systems are used to navigate, give weather updates, and offer location information. The GPS systems are linked to satellites which, in turn, feed the GPS system with pertinent data. GPS systems in vehicles are used to help in navigation. Some digital cameras also inlude GPS, which enable the photographer to see the latitude and longitude of the photograph.
Global Positioning System (GPS) uses timing signals from four satellites to determine your latitude,longitude, altitude and precise time.

Global positional systems (GPS) work by triangulating your position based upon finding your longitude and latitude. A device will find longitude and latitude and the GPS will read that and translate it into maps.

Yes, an infinite number of them. Longitude and latitude only apply to points on the surface of the earth, or on the surface of the few other bodies in the solar system to which local coordinate systems have been assigned. The surface of any other body, or the space between solid bodies, are enormous regions without latitude or longitude.
-- Your height and weight are natural. The systems you use to describe your height and weight to people who can't see you are man-made. -- The latitude and longitude of a place on Earth are natural. The systems we use to describe the latitude and longitude of a place are man-made. 'Lines' are an irrelevant distraction in this discussion, just as the marks on the ruler and the bathroom scale are.
