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 can also be used to track moving objects via mobile beacons
attached to them. Other applications include, for example, forklifts, virtual reality (VR)
systems, helmets for construction workers or miners, etc.
The navigation system consists of a network of stationary ultrasonic beacons
interconnected via radio interface in a license-free band, one or more mobile
beacons installed on objects to be tracked and modem providing gateway to the
system from PC or other computers.
Mobile beacon’s location is calculated based on a propagation delay of an ultrasonic
pulses (Time-Of-Flight or TOF) between stationary and mobile beacons using
trilateration algorithm.
The system can build the map of stationary beacons automatically. Thus, in simple
cases, no additional manual data input or any manual distance measurements are
required. This map formed once can be frozen and stored in modem’s memory and
the system becomes fully active within 7 to 10 seconds after the modem is powered.
Minimum configuration requirements to ensure optimal performance of the
Marvelmind Indoor Navigation System:
- For 3D (X, Y, Z) tracking: an unobstructed line of sight (hearing) between a mobile
beacon and 3 or more stationary beacons within 30 meters
- For 2D (X, Y) tracking - an unobstructed line of sight (hearing) between a mobile
beacon and 2 or more stationary beacons within 30 meters
