This paper addresses the NLOS detection and error mitigation of differential time of arrival (TDoA) topologies in localization systems. The localization error of such systems is hard to detect mainly due to the differential structure of the network.

This paper evaluates and compares the accuracies of the three commonly used Bayesian filters namely extended Kalman Filter (EKF), H-infinity filter and unscented Kalman filter (UKF) in differential time of arrival (TDoA) localization topology in ultr

Ultra-wideband systems (UWB) are a common technology which is used for indoor localization applications due to its accuracy. However there are some challenges to implement these systems in indoor area with obstacles and barriers. One of the challenge

This paper discusses the synchronization issues of the unilateral TDoA method applied in ultra-wideband (UWB) localization systems. Focus of the paper is on implementation aspects of the synchronization. At first, the structure of unilateral TDoA met

The large bandwidth of the UWB (UltraWideband) communication systems, makes it ideal for time of travel localization techniques such as ToA (Time of Arrival) and TDoA (Time Difference of Arrival). The techniques based on ToA demand high rate of netwo

In this paper, we advance the thesis that educational robots can make a much larger contribution in the classroom than has hitherto been the case. However, to realise this potential, it is necessary to supply teachers with detailed guides for classro
