The Marvelmind Modem HW v4.9 (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.

Router / Modem:
The router is the central controller of the system which calculates position of mobile beacon (“hedgehog”) 16 times per second based on data from beacons. They communicate via USB with dashboard and with beacons wirelessly in ISM band.

Features:

• High-precision (+-2cm) indoor navigation system for autonomous robots and systems (“indoor GPS”)
• Indoor tracking and positioning of objects and humans equipped with beacons
• Coverage radius of a beacon: up to 50 meters
• Up to 1300h (>100 days with 12h/day & 1Hz location update rate) in active mode when powered from battery. Up 2y in deep sleep mode
