How a Mio navigation device works

A satellite navigation device, such as the Mio Moov uses the global positioning system (GPS) to pinpoint exactly where you are on the planet. It detects signals from at least three satellites in a constellation of around 30 constantly orbiting the earth.

GPS imageUsing the data transmitted at the speed of light by these satellites the Moov’s internal electronics convert the signals into distances between the device and each of these satellites. It then reckons its precise position using trilateration, which is essentially a mathematical formula programmed into the navigation device.

The same calculations not only provide the position, but also lock that on to a position on the device's built-in maps; it then calculates the speed and direction you are travelling.

GPS imageThe Navigation device uses the information obtained from the GPS to overlay your exact position on to the map for the area in which you are travelling.The maps used in Mio devices are regularly updated and can be added at any time.

Software built into the Navigation device allows you to set a destination and will guide you along the best route. The device can also read data from TMC (Traffic Message Channel) and alert you to traffic problems on major roads and optionally give you a revised route.

Mio Navigation devices also have built in information on safety cameras. The location of safety cameras is constantly changing so updates can be downloaded regularly. Some models will warn drivers when they are approaching a safety cameras based on your direction and speed.
