Automotive navigation system. Also known as Car Navigation System , it is a GPS designed to navigate on road vehicles such as cars, buses and trucks in which other factors such as the use of satellite systems and a database of plans are taken into account .

origins
Honda created the first navigation system in 1983 , culminating in 1990 for the Acura Legend . This system used an analog system and an accelerometer to fix the locations, since the GPS system was not yet available. Instead, Pioneer claims that they were the first to have an automotive navigation system with GPS , in 1990 .
Description
The car navigation system is nothing more than a GPS designed to navigate on highway vehicles such as cars, buses and trucks. Unlike other GPS , it uses position data to locate the user on a street mapped in a database system . Using the information from the street files in this database, the unit can give directions to other points throughout the city .
With calculations by inference, distance data from sensors strategically installed in the city, and an inertial guidance system with a vibrating gyro structure, safety can be greatly improved, since the GPS signal can be lost or suffer multiple multi-pass bounces through urban canyons or tunnels .
The navigation system or Global Positioning System (GPS) indicates how to go from one place to another, indicating the best routes with exact precision. Similarly, it tells you the location of some stores, restaurants and service centers, among others. You only have to enter certain data. The results are not long in coming. Some new vehicle models have it incorporated as part of the advantages they offer to buyers. Manufacturers, who always think of all types of consumer, also offer drivers who own a vehiclewhose model does not incorporate the navigation system, GPS systems that can be installed in the car. Many of them are portable. Different models and prices are available for all tastes, needs and economic possibilities.
Combinations
- General view of the letter.
- View of the chart in rotation just like the vehicle.
- Aerial view of the area being mapped, and of the places ahead (on the next curve).
- Union by lines of different spaced points, redundant, if you are using a rotary chart.
- Numbers for the distance.
Street database
The street database is a vector map of the areas of interest. The names of the streets, and the numbering are coded in geographic coordinate so that the user can find the desired destination by street and address. Points of interest are included in the geographic coordinates. The contents can be viewed by the user while he drives his car along the streets and updates his maps via the Internet.
Satellite system
GPS generally uses satellites to determine where you are and where you are going. Usually the user enters the address in which he is and to which he wishes to go. The Navigation System screen will display a map of the route to follow; Likewise, the system will indicate when to make turns and the distance that remains to be traveled to reach the next corner where you should turn.
If the user deviates from the proposed route, the system can on many occasions redesign the route to follow. However, this system is still not excellent at indicating routes to skirt areas with high traffic. The good news is that manufacturers are working on developing this technology .
