Automotive Navigation System

ANS is GPS Navigation System used for automobiles. It uses GPS Navigation (from satellite) to find its position on earth to locate where they are in the area. Also by using the road database (that is updated hourly) the driver may find routes to any locations they may want to travel to. The system itself could calculate numbers of route and find the fastest way to get to the location.

The GPS system sees the addresses and street numbers as geographical coordinates.

Th GPS could show where the speed cameras are, fuel stations, mini stores, restaurants, and tour sites.

Companies such as Mercedes, Toyota and Subaru locks most of the features in the GPS while driving. Features such as watching TV, playing games, going to internet etc are locked while driving for safety reasons. Some features are enables such as music player, radio, and telephone calls.
 * Controversy**

Misdirections are common as well. There were numbers of accidents by the GPS system and people have died because of the errors. Here are a couple of examples of the errors: "In [|Exton, Hampshire], the County Council erected a sign warning drivers to ignore their "sat nav" system and to take another route, because the street was too narrow for vehicular traffic, and property damage resulted from vehicles getting stuck." - [|HGVs told to ignore sat-nav guide]", [|BBC News] ([|2007]-[|02-19]).

"On May 11, 2007, a driver followed satnav instructions in the dark and her car was hit by a train on a rail crossing that was not shown on the system." - [|Woman runs for her life after satnav leads her into path of a train]", [|Daily Mail] ([|2007]-[|05-11]).

GPS vs Speed Camera Accuracy
The GPS speed meter is much more accurate than speed gun. This is because the GPS receives the speed directly from the car.

"In July 2007, an Australian man successfully overturned a speeding conviction after evidence from a GPS [|navigational track] proved that he did not exceed the speed limit." - [|GPS beats radar gun]", [|Herald Sun] ([|2007]-[|06-02]) . Retrieved on 2007-10-10.
