Where the GPS or Global Positioning System depends on signals received from 3 or 4 of the 32 satellites in orbit around the Earth, the Consui-IPS makes its calculations solely based on the information provided by iBeacons.
These are small electronic devices designed by Apple, but produced by Consui, that send a Bluetooth signal every 100 milliseconds, to be picked up by smartphones in the vicinity. This information can then be used in any mobile application linked to servers on the Internet.
In a tunnel, train or on board a ship, there are often difficulties to receive satellite information, because the satellites are not or do not remain ‘in sight’ of the terrestrial receiver. Also, many tall buildings or complex facilities are functioning as a Faraday’s cage and make it impossible to receive a very weak signal from a very high altitude.
