GPS – A Short Introduction
GPS, which stands for Global Positioning System, is a satellitenavigation system that can ascertain the latitude and longitude of a GPS receiver device on the Earth.

Each satellite transmits radio signals, which can help determine the location, speed and direction of travel of users equipped with GPS receivers. To ensure that the whole world is covered by the constellation of the GPS satellites, they are so arranged that four satellites are positioned in each of six orbital planes.
