An Ultra-wideband Battery-less Positioning System for Space Applications
An ultra-wide bandwidth (UWB) remote-powered positioning system for potential
use in tracking floating objects inside space stations is presented. It makes
use of battery-less tags that are powered-up and addressed through wireless
power transfer in the UHF band and embed an energy efficient pulse generator in
the 3-5 GHz UWB band. The system has been mounted on the ESA Mars Rover
prototype to demonstrate its functionality and performance. Experimental
results show the feasibility of centimeter-level localization accuracy at
distances larger than 10 meters, with the capability of determining the
position of multiple tags using a 2W-ERP power source in the UHF RFID frequency
band.Comment: Published in: 2019 IEEE International Conference on RFID Technology
