A Platform That Provides Centimeter Accurate Positioning And Motion Information

Share via AddThis
Posted June 9, 2015

Pozyx is an Arduino-compatible platform that provides centimeter accurate positioning and motion information both indoor and outdoor. In order to achieve a positioning accuracy of a few centimeters, the 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.

Ultra-wideband (UWB) technology is the key to accurate ranging and positioning, the UWB-module itself only provides accurate timestamps.

3D positioning requires at least 4 anchors to be within range (3 for 2D positioning). Pozyx provides the feature to obtain the anchor positions with a single line of code. It is equipped with an accelerometer, gyroscope and magnetometer. With these sensors it is possible to obtain the orientation of the device.  Pozyx offers 9-axis sensor fusion (3 axes for every sensor).
