2. Executive summary
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.
The stationary beacons form the map automatically. No manual entering of
coordinates or distance measurement is required. If the stationary beacons not
moved, the map built only once and the system is then ready to function after 7–
10 seconds after the modem powered
Key requirements proper system functionality
- For 3D (X, Y, Z) tracking - An unobstructed sight by a mobile beacon of three or
more stationary beacons simultaneously
- For 2D (X, Y) tracking - An unobstructed sight by a mobile beacon of two
stationary or more stationary beacons simultaneously
Distance to the nearest 2 or 3 beacons – not more than 30 meters
