The Indoor Navigation Positioning Mobile Beacon w/ Case (915MHz) is part of a system of stationary ultrasonic beacons united by radio interface in ISM band. Location of a mobile beacon installed on a robot (copter, human) is calculated based on the propagation delay of ultrasonic signal to a set of stationary ultrasonic beacons using trilateration. The kit consists of one mobile beacon, four stationary beacons and one router.
