Definition of system navigation for car

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


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 locations, since the GPS system system was not yet available. Pioneer claims instead that they were the first to have a GPS - enabled automotive navigation system, in 1990.


The car navigation system is nothing more than a GPS designed to navigate in road vehicles such as cars, buses and trucks. Contrary to other GPS, this one uses position data to locate the user on a street mapped street 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 inference calculations, distance data from sensors strategically installed in the city, and an inertial guidance system withWith inference calculations, distance data from strategically placed sensors in the city, and a vibrating frame gyroscope, safety can be greatly improved, as the GPS signal can be lost or bounced from multiple passes 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 indicates 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 offered to buyers. Manufacturers, who always think of all types of consumers, 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.


  • General view of the letter.
  • View of the card in rotation just like the vehicle.
  • Aerial view of the area that is being mapped, and of the places further on (in the next curve).
  • Union by lines of different distant points, redundant, if a rotating card is being used.
  • Numbers for the distance.

Street database

The street database is a vector map of the areas of interest. Street names and numbers are encoded in geographic coordinates 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 through the Internet.

Satellite system

GPS generally uses satellites to determine where you are and where you are going. Usually the user enters the address where he is and to which he wants to go. The Navigation System screen will display a map of the route to follow; likewise, the system will indicate when you must make turns and the distance that remains to be covered to reach the next corner where you must turn.

If the user deviates from the proposed route, the system can often redesign the route to follow. However, this system is still not great at indicating routes around high-traffic areas. The good news is that manufacturers are working on developing this technology.
