GPS stand for Global Positioning System. It's a technology that is relatively new, but has proven so useful that it's now common around the globe. GPS products make traveling easier and safer than ever before.
GPS technology is most useful in the areas of mapping and navigation. Navigation can mean anything from planning a trip around the world in a sailboat to planning a hike through the local forest. GPS navigation systems are particularly popular among car owners. GSP for cars is a great fit, as it makes driving on unknown roads in unknown areas much easier. The days of getting lost are in the past.
Global Positioning System technology is a worldwide network of information. It works by using a series of satellites to determine to location of a GPS receiver on the surface of the earth. The method is similar to triangulation, a term you're probably familiar with if you like spy movies.
While GPS technology may seem cutting edge, it has its roots in the radio navigation systems used in World War II. These systems worked well for the time, but they only worked within a limited radius and could be affected by adverse weather conditions. GPS devices work at any time of day, anywhere on the planet and in any weather conditions.
GPS technology can be used for more than navigation, it can also be used for tracking. GPS tracking has very useful applications in the field of personal security and theft deterrence. After all, would you steal a car that could send information about its whereabouts to the local authorities?
Many parents have begun to use GPS devices (or cell phones with GPS capability) as a way of monitoring their children. It allows parents to monitor the location of their kids and sounds an alert if the kids wander outside the designated "geofence" area.
An interesting development in the world of GPS is the activity of geocaching. Geocaching is an outdoor activity (some might call it a game) that involves using GPS receivers to find containers that have been hidden by other geocachers. Usually, containers are waterproof and contain a logbook that you are asked to sign when you locate the container. There are currently over 500,000 geocaches in the world, in 100 countries and on all seven continents.
