The invention of the GPS navigation system is not as new as most people think they are round and ever since the first GPS satellite was used to space back in 1978 launched. Global positioning satellites have many civilian and military applications, but one of the most common is the navigation.
  However, with a GPS navigation system in an ordinary car is a little different than you on the airplane. Transport by car on the road, traveled to depend on. In reality, the GPS measurements are only such as length, width and height for all practical purposes, useless if you drive to Aunt Mabel's house. When driving a car, you may end up going through through urban canyons and tunnels, where the satellite operator singles can not. So a different kind of GPS technology for automotive GPS navigation systems required.
  It has potential for years in automotive GPS navigation systems, and industry has tried various ways to implement them. In 1983, Honda introduced a car navigation system, which was based primarily on an accelerometer, not GPS. It was not until 1990 that an auto GPS system has been released to the public consumers of Pioneer. Automobile GPS Navigation systems are yet to be fully used until the Magellan version in the U.S. published in 1995. Since then, more portable GPS systems have been for a greater ease of use for people were developed.
  Automobile GPS Navigation System Components
  A car GPS navigation system requires a GPS receiver and a map database. Some systems have also complement the powertrain sensors when GPS signals are blocked for a short time.
  The database card converts the GPS coordinates in portable systems, map locations, such as street names and addresses. Some databases contain map GPS coordinates for specific locations, such as sightseeing or resting places. It is the information in the database, however, that guides you your position, either visually or by voice. Which means your GPS navigation system is only as good as your car GPS map database systems.
  Commercial Applications
  Many corporations and businesses use the GPS navigation system to send in their cars and track cars. In various cities in the U.S., taxis are equipped with a GPS navigation system. Dispatchers at the taxi company know where all the taxis are at any given time, and can lead to a Friend efficiently than before.
  Commercial shipping companies you will find GPS navigation systems is essential. In addition to the ability to track where the trucks are, whenever they want, they can also provide customers with a tracking number, then the customer would be the possibility of having to keep track of their individual mission.
