Gps: Technology at Its Best

The automobile industry has seen a terrific change in the last decade. From passenger side air bags to ubiquitous car alarms, everything has been neatly incorporated in the latest car models. And of course, there are numerous add-ons as well - like CD and DVD players. GPS navigation (Global Positioning System) is another cool feature which comes installed in some of the latest car models.
GPS is a satellite-based navigation system which is made up of a network of 27 satellites. These satellites have been placed into the orbit by the U.S. Department of Defence. GPS was initially meant for military applications; it came into civilian use since the 1980s. But unlike today, the system was not available with cars as well as mobile phones. Nowadays, many companies have launched GPS mobile phones and GPS-enabled cars which help one to get a glimpse of his/her position in a specific geographical location 24 hours a day.

GPS navigation incorporates maps of different countries thus helping the car owners or mobile phone users to be on the right track while making a journey. While driving a GPS-enabled car, you are informed about alternate routes if you get stuck in a traffic jam. It also guides you to the nearest restaurants, gas stations and other points of interest.

Many of them come with internal GPS navigation system, while some models can be loaded with handheld devices that can be mounted right on the dashboard. Coming onto the GPS enabled mobile phones, like a navigation system, GPS mobile phones are very helpful in getting step-by-step direction towards a destination. The main advantage here is that it has got re-routing potential. When the user moves towards a wrong direction, the GPS mobile phone warns him/her about that and helps him/her in guiding towards the right destination.
