GPS Receiver with Extended Data Output

GPS is a system designed for positioning objects on and around the earth based on a one-way communication between the satellites and the GPS receiver. Since the satellites emit timed signals that include a code telling its location and the time of emission, the receiver is able to calculate the time lapse of each signal, thus determine the distance in between the satellites and receiver when the signal is emitted. The goal of the GPS is to determine the receiver’s position on Earth in three dimensions, i.e. longitude, latitude and altitude.

In this project, a GPS module with extended data output is connected to an Arduino board so as to build a home-made and cheap GPS receiver.
