Abstract
An ultra-wideband (UWB) tracking device, system, and method are provided. The system can include a plurality of anchor transmitters, at least one location device, and a processing system. The anchor transmitters can be arranged in predetermined positions, include a unique identifier, and each transmit an ultra-wide band (UWB) signal including the unique identifier. The location device can receive the UWB signals, and transmit the unique identifiers. The processing system can include a digital map that stores the unique identifiers and the predetermined positions. The processing system can receive the unique identifiers from the location device, and identify a position of the location device based on a comparison of the unique identifiers received and the stored unique identifiers on the digital map.
