A GPS device like the Mio Moov based on the geographical location system ( GPS ) to pinpoint your exact position on Earth. It detects signals from at least 3 satellites in a group of 30 satellites in medium, the latter being in orbit around our blue planet.
From the data transmitted by satellites to the speed of light to the electronics of Moov, the signals are converted to obtain the distances between the unit of each satellite. Car GPS calculates its exact position by trilateration, through a mathematical formula programmed into the device. Similar calculations provide the position, but lock in the maps included in the device, it then calculates the vehicle speed and the direction in which you move.
The navigation device uses the GPS information to overlay the exact position on the map corresponding to the zone you cross. The maps used by Mio devices are updated regularly and you can add at will.
Software embedded in l1'appareil navigation allow you to set a destination for the GPS to guide you via the optimal route. The device can also read the info on the TMC (Traffic Message Channel) and alert you if a problem on major roads, giving you the option of forking over another route.
Mio navigation devices also contain information on traffic radar. As their position is constantly changing, updates can be downloaded regularly. Some models warn the driver when approaching speed cameras, according to the direction and speed of the vehicle.
The geographical positioning system (GPS) is a constellation of satellites orbiting Earth, he sends a signal to receivers and GPS navigation devices, giving them the exact position, speed and altitude (if you're plane or on top of a mountain).
To maintain optimal utility of GPS, you must regularly update the GPS mapping software. Every year, about 5% of roads are changed in one way or another: building a bypass, additional lanes on roads, changing speed limits, introduction of one way streets, and changing traffic lights. Your navigation device needs to rely on a mapping software which is regularly updated.
This is the main advantage of a digital mapping device, such as GPS car. Gone are the traditional consulting maps, which in some regions, are already outdated before you even take the wheel.
The digital map companies are constantly working to update the GPS mapping software and make it available to users as quickly as possible, with maximum efficiency. The digital maps are provided with detailed functions showing the streets, which allow you to get from A to B as easily as possible.
GPS satellites do not provide the cards - they give the locked position, your GPS device then superimposed on maps. All units are equipped with navigation maps preloaded, but to be sure that your GPS is equipped with the latest maps, you need to install regular updates of GPS mapping software.
The updates are available in two formats: you can either buy an expansion card to your dealer or go online and download updates on your computer to install the next time you connect your GPS unit.
