GPS – Global Positioning SystemGPS – Global Positioning System
•GPS is a worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations.
•GPS uses these "man-made stars" as reference points to calculate positions accurate to a matter of meters or even centimeters with certain units
•In a sense it's like giving every square meter on the planet a unique address.
