We currently perform research on the following topics:
Personal localization in indoor / GPS-denied environments, based on radiofrequency signals, pedestrian dead reckoning (PDR), environment maps, and the use of signals of opportunity. More info.
Fine-grained acoustic positioningFine-grained acoustic-based positioning, by using coded acoustic / ultrasonic signals for ranging, achieving precisions of 1 cm or less in restricted 3D spaces. More info.
