Real Time High Accuracy Tracking / Locating Solutions (RTLS)

The system consists of positioning sensor (Anchor), positioning Tag (Tag) and software platform. The positioning sensor is installed at fixed position. The tag is worn
or mounted on the object to be tracked.
Tag launches UWB signal to measure the range between each sensor, and back-end software platform use the TOA and TDOA algorithm to calculate the position.
