By measuring the travel time of the signals, the robot can calculate its distance from the beacons and therefore its position. It is accurate up to 20 centimetres without needing line of sight.
Spectrum UWB localization system
The Avular Spectrum system uses ultra-wideband technology and is suitable for both indoor and outdoor applications. Its beacons function as satellites, communicating with the mobile robot. By measuring the travel time of the signals, the robot can calculate its distance from the beacons and therefore its position. It is accurate up to 20 centimetres without needing line of sight.
