Marvelmind Indoor Navigation System is an off-the-shelf indoor navigation system designed to provide precise (±2cm) location data to autonomous robots, vehicles (AGV), and copters. It also used to track other objects that the mobile beacon installed on, for example, virtual reality (VR) systems, helmets for construction workers or miners, etc.
The navigation system based on stationary ultrasonic beacons which united by radio interface in a license-free band. The location where a mobile beacon installed is calculated based on the propagation delay of an ultrasonic signal (Time-Of-Flight or TOF) to a set of stationary ultrasonic beacons using trilateration.
Key requirements proper system functionality:
Distance between beacons
Location update rate
