GPS - Global Positioning System

GPS helps you determine exactly where you are, but sometimes important to know how to get somewhere else. GPS uses satellites as reference points to calculate positions accurate to a matter of meters in seconds. GPS receivers have been miniaturized and are becoming very cheap and widely available. These days GPS is finding its way into cars, boats, planes, construction equipment, movie making gear, farm machinery, even laptop computers.
