The i-Zone-3 GPS Satellite Navigation system utilizes a number of sources in order to pinpoint a vehicle's location.

The first of those, and most important is a Global Positioning Satellite (GPS) signal.  These are signal transmitted by a constellation of satellites orbiting the Earth.  By reading their signals a good global position can be deduced of the vehicle.  GPS signals can also be enhanced via another satellite constellation called GLONASS.

In addition to standard GPS positioning, onboard instruments are used to compensate for any GPS errors.  Onboard sensors include a gyroscope and a velocity sensor.  In advanced designs, other sensors, such as accelerometers, can also be added. The onboard sensors perform Dead Reckoning calculations to determine the vehicle's position if the GPS signals become lost or deteriorated - they also supplement and enhance strong Satellite signals. 

Having determined the vehicle's global position, this position needs to be translated to an actual position on a real map.  i-Zone-3 currently uses TeleAtlas ( Click here for TeleAtlas' Website) mapping data for excellent North American and Western European road coverage.

The mapping data allows the navigation system to calculate the optimum route from A to B based on either speed or distance.

The next stage in navigation is to incorporate Traffic Data, so that the routing system can avoid traffic jam spots.  This is achieved via a wireless data link to an i-zone-3 traffic data base which works with the routing system.

The i-zone-3 navigation system takes into account fuel levels, gas station locations and even rest areas and hotels.

Through our Trip Management Software, you can plan your journey carefully, allowing the system to automatically figure out where and when you'll need to fill up, and where you can book a hotel or take a rest.

We are continually enhancing our system design and we value your input as a driver.  If you have any particular custom navigation facility you would like for your vehicle, please feel free to contact us about this.
