Ultra-wideband technology

The pozyx system is a hardware solution that provides accurate positioning and motion information. The systems consists of 5 modules, of which 4 anchors and one tag. In order to achieve a positioning accuracy of a few centimeters, the pozyx system relies on a novel wireless radio technology called ultra-wideband (UWB). The accuracy achieved with this ultra-wideband technology is several times better than traditional positioning systems based on WiFi, bluetooth, RFID or GPS signals. Furthermore, the signals can penetrate walls and make it suitable for indoor environments.

Some things you can do with pozyx:
  • Let your robot or drone navigate safely inside your house.
  • Let the environment respond to your presence.
  • Measure any distance, even through walls!
With 4 years of research experience and some recent developments in wireless UWB technology we are now able to deliver the best possible positioning system out there at an affordable price!

Indoor ranging and 3D positioning

Ultra-wideband (UWB) technology is the key to accurate ranging an positioning. However, the UWB-module itself only provides accurate timestamps. We have implemented state-of-the art algorithms to obtain the most accurate range and positioning information.

Automatic anchor calibration

3D positioning requires at least 4 anchors to be within range (3 for 2D positioning). In general the position of these anchors must be known in advance. Our shield provides the feature to obtain the anchor positions with a single push of a button. No manual measuring required!

Remote control

With the use of ultra-wideband wireless technology, messages can be transmitted over the air. These messages can be text or user data, but also commands to control remote pozyx modules. We made it possible to remotely turn on LEDs, toggle pins, read out sensor data, and much more.

9-axis sensor fusion

Pozyx is equipped with an accelerometer, gyroscope and magnetometer. With these sensors it is possible to obtain the orientation of the device. However, separately these sensors all have their flaws. For example, the accelerometer is noisy and the gyroscope is biased. Together these flaws can be mitigated. Pozyx offers 9-axis sensor fusion (3 axes for every sensor) to get the best possible measurements.


By default, we program the board with our firmware for localization and tracking. However, it is possible to reprogram the microcontroller to suit your own needs. Using the debug pins (SWD), you can load your custom code on the microcontroller of the board. We provide you with detailed tutorials and example files that take care of all the configuration: gpio pins, leds, and all the sensors (through SPI or I2C).
