Data Sheet

Stationary beacons:
– Mounted on walls or ceilings
– Measure distance to other beacons
using ultrasonic pulses (time-of-flight)
– Communicate with router wirelessly
in ISM band
Distance between
beacons-neighbors
is up to 50 meters
.
Router/modem:
– Central controller of the system
– Calculates position of mobile beacon up to 45 Hz
– Communicates via USB/virtual UART with
Dashboard or robot
Mobile beacon:
– Installed on robot and interacts with it
via UART or SPI or I2C or USB
– Receives location update from router
up to 45 times per second
– May contain IMU (accelerometer +
gyroscope + compass module)
Beacon N
Indoor “GPS” (±2cm) – architecture
Indoor Navigation System
consists of:
– 2 or more stationary beacons
– 1 or more mobile beacons
– 1 central router
Beacon 1
Beacon 3
Beacon 2
Submaps:
– Advanced feature that allows building
independent maps/clusters of beacons in
separate rooms and thus covering large
buildings (with area of thousands of m2)
similar to cellular network coverage
Key requirement for the system to work
well: unobstructed sight by a mobile
beacon of 2 or more stationary beacons
simultaneously (like in GPS)
