Time and position of the satellites.
Where you are and how fast you are traveling.
A user can typically observe at least 4 GPS satellites anywhere on Earth to accurately calculate their position using trilateration.
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
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 Global Positioning System (GPS) is a system that uses signals from satellites to provide precise location information on Earth. GPS receivers can calculate latitude, longitude, altitude, and time data to determine an exact location.

Global Positioning System. IT was in my sixth grade science bk.
A Global Positioning satellite is one of several satellites that orbit the earth constantly broadcasting a signal the give their location. Collectively these satellites are called the Globle Positioning System or GPS. Global Positioning means the system is used to determine your position on the globe -- your latitude and longitude. GPS receivers can receive signals from these satellites and use them to calculate where on the earth the receiver (and thus the person with the receiver) is.
