Just as hands free car kits have become a must have in you vehicle sat nav systems are quickly following suit. In the past you would have to carry a ton of maps around with you whenever you travelled around.
However now that satellite navigation systems have come along this is no longer necessary. Not is a sat nav take you to your destination it will also plan the entire route for you in order to reduce your total travelling time.
Clearly there is an advantage in a sat nav system that you are not required to plan the journey yourself. This most affects deliver drivers who often make use of vans. Because a delivery driver can be expected to travel anywhere in the country it will never be possible for them to learn all the available route that they can take to make their deliveries in the least amount of time. This is where a sat nav system becomes invaluable because it is able to significantly reduce delivery time. The reason is because now the driver doesn’t have to plan the best route to their destination they simply enter the points into the device.
All sat nav’s currently use the Global Positioning System (GPS) which is run by an American company. However there is expected to be some competition in Europe to come in 2012 when the Galileo system is set to come online. The Russians (GLONASS) and Chinese (COMPASS) also have their own positioning systems under development. With the new sat nav positioning systems there will be no compatible issues to worry about with current systems.
Using a network of satellites equipped with atomic clocks the system is able to locate the position of a device in relation to the globe. The satellites send a message containing the time, orbital position and health of the satellite down to earth. From this a device equipped with a satellite navigation receiver is able to determine its own location and relay this to the user of the device.
