The Importance of GPS
GPS refers to Global Positioning System, an electronic satellite based system. The service is offered by the US department of defense that has launched 24 satellites into orbit above the earth to provide satellite-based navigation system. It was a system originally intended for military applications before being made available for civilian use in the 1980s. The GPS transmits signal information to the earth at all times, in any weather and to any place on earth. GPS receivers use this information to calculate the user's exact location which is displayed on the units map.
It is much safer to use a GPS device than a map for the electronic device is automated and lets the driver focus on the road instead of the map. The popularity of the system is due to the fact that people who travel long distances to get home or work are provided with the shortest routes that can avoid highways for example. People who buy items from estate or yard sales do not have to keep following confusing signs. All they do is plugging in the address and get there in the shortest time possible. For travelers the GPS device is ideal as it is portable and easy to go places after renting a car in foreign locations.
GPS is most important to people who drive into unfamiliar territories or go for hikes, business travelers who frequent new cities and towns. Business people in new cities do not have to get late for their meetings because they got lost. Audio voice prompts are used to guide drivers to their right locations. People who are in different cars and have laptops need systems installed to aid in communicating. Having a GPS system helps users to maneuver one way streets that they have not memorized while avoiding the non through streets. Paper maps are still being used by many people but they cover interstates unlike POIs that inform users on rest areas, food and gas places that are ahead in their route. The system offers quick and accurate routing to locations in strange areas and so users are not stressed when looking for unknown locations while on road trips or vacations.
Car manufactures are installing communication devices like IVNS to provide real-time traffic data that is integrated into the GPS technology. Other cars have to be installed with the system after being bought. Before buying the GPS device people need to consider things like price and the models reliability. The technology of the system keeps getting advanced and thus more expensive. Owning the GPS device is however a big investment. Reliable devices are evaluated by their performance and so people need to read their reviews found in the browsers. The seller's feedback is also a good pointer on the best available systems. The devices features are another consideration and they include the size and color of the screen. People should also consider the factory warranty and whether they require a monthly subscriptions service that is available on some models.
