In recent years, ultra-wideband radio technology has become increasingly popular as a space-and cost-effective solution to the problem of indoor localization. This paper demonstrates how measurements of the channel impulse response can be used to estimate a signal's angle of arrival at a receiving a…
A method for recovery from the complete loss of the state estimate is presented for autonomous quadcopters. Given an aerodynamic force model, the only measurements used to reinitialize the state estimate by means of a bank of extended Kalman filters are the angular rate and linear acceleration measu…
A robot localization system is presented that enables a robot to estimate its position within some space by passively receiving ultra-wideband radio signals from fixed-position modules. Communication from the fixed-position modules is one-way, allowing the system to scale to multiple robots. Further…
