How GPS receivers can help youConsumer GPS receivers are used mainly for navigation and route planning. By locking on to a constellation of satellites orbiting the earth, the receiver can pinpoint your exact position on the planet, calculate the speed and direction in which you are travelling, whether you are in a vehicle, a boat, or walking, and if you are in an aircraft it will tell you your altitude too.
Drivers - Most drivers, whether driving for business or pleasure can benefit from the satellite navigation made possible by a GPS receiver. They can find their exact location and follow a route from A to B provided by the navigation device.
Safety Cameras - GPS based navigation devices have made spotting permanent safety cameras on the roads that much easier so that drivers can make sure they stay within the roads speed limit.
Traffic Jams - Some GPS receivers and navigation devices are able to access traffic news announcements and alert drivers to problems on the road ahead and help them by re-route their journey to avoid traffic jams and accidents.
Entertainment - Your Navigation device can even help you plan your day if it has POIs (points of interest) such as restaurants, gas stations, emergency assistance, hotels and more, embedded in the mapping software.
Outdoors - Hikers, cross-country runners, tourists, and others can use a GPS receiver to pinpoint their location and find their way from landmark to checkpoint and safely back home. A GPS can be used to mark a particular spot on the map so that you can return to that exact location later.
Gaming - Outdoor gamers can even use a GPS receiver to take part in treasure hunts for the digital age known as geocaching. The organizers hide a cache of "treasure" at a secret location and then provide clues to its whereabouts that rely on your use of a GPS receiver to find the bounty.
