A new paper demonstrating the power of the Kalman filter is now available. GTPG researcher Qian Yang and coauthors use sensor-fusion data from a microwave backscatter link to demonstrate mm-scale localization of RF transponders. This study is unique because it breaks down the individual contributions of signal strength, backscatter phase, and inertial sensor measurements to a very precise position estimation problem. This work is an important next-step in the “holy grail” of wireless position location: precise motion-capture at a distance in 3D.
