Marvelmind Indoor Navigation System is 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 other objects with a mobile beacon installed on them, for example, forklifts in warehouses or virtual reality (VR) helmets or helmets for construction workers or miners, etc.

The navigation system is based on stationary ultrasonic beacons united by radio interface in a license-free band (433MHz or 915MHz). The location of a mobile beacon 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. No manual calibration is required. No need to know exact locations of the beacons – the system builds the map of beacons automatically.

The set contains a mobile beacon with IMU that gives a possibility for ultrasonic + IMU (3D accelerometer + 3D gyro + 3D magnetometer) fusion. That allows much faster update rate – up to 100Hz and above.

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 (recommended). In ideal conditions – up to 50 meters
• Mobile beacon with IMU onboard
