The Marvelmind Starter Set HW v4.9 Indoor Navigation Positioning System (915MHz) is 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 modem.

Beacons:
Beacons are mounted on walls or ceilings to measure distance to other beacons and “hedgehog” using ultrasonic pulses. They communicate with the modem wirelessly in ISM band (915 MHz). Powered by LiPo battery or USB and offering an update rate is 0.05-25Hz.

Mobile beacon (“hedgehog”):
This is installed on robots and connected to it via UART or SPI or I2C or USB. Calculated coordinates (±2cm) are sent to the modem and updated 16 times per second. Powered by LiPo battery or USB or from robot.

Modem:
The modem is the central controller of the system which calculates the position of the mobile beacon (“hedgehog”) 16 times per second based on data from beacons. They communicate via USB with a dashboard and with beacons wirelessly in the 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
• Coverage area: up to 1000 m2 with the Starter Set configurations

Uses:

• Advertising
• Gaming and hobby
• Automatic delivery
• Dangerous places
• Security systems
