Starter Set HW v4.9 is a precise indoor positioning and navigation solution for various applications including autonomous robots, autonomous drones, autonomous vehicles. It also works very well for precise localization and distance measurement in industrial applications, for example: tracking of relative position of vehicles and assets; increasing safety by preventing of violation of geofencing zones; improving productivity by creating heatmaps of movements of vehicles inside a plant or a warehouse.Content:

We always recommend to check your country’s local regulations. 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 is also used to track other objects that the mobile beacon installed upon, for example, virtual reality (VR) systems, helmets for construction workers or miners, etc. The navigation system is based on stationary ultrasonic beacons that are united by radio interface in a license-free band (433 MHz or 915/868 MHz). 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 for the 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
Technical Details
Distance between beacons
Reach up to 50 meters in lab conditions
Recommended distance is 30 meters (Transducer4 to Transducer4 looking straight at each other and other transducers are off)
Coverage area
Reach up to 1000 m2 with the Starter Set configurations
Coverage for larger territories is similar to cellular networks
Location precision
Absolute: 1–3% of the distance to the beacons
Differential precision: ±2 cm
Location update rate
0.05–25Hz
Can be set manually
Depends on the distance between the mobile and stationary beacons (shorter distance — higher update rate)
Depends on the number of mobile beacons: for example, update rate of 25Hz for 1 mobile beacon will result in update rate of 25Hz/2 for 2 mobile beacons, and 25Hz/3 – for 3 mobile beacons, etc
Depends on the radio interface profile (500kbps vs. 38kbps)
Slightly depends on the number of stationary beacons — different than for mobile beacons
Power supply
Internal:
LiPol battery 1000mAh
Battery lifetime depends on usage
Stationary beacon with 16Hz update rate => up to 72h (tested)
