    When localising an object in a confined environment using an indoor positioning system (IPS) based on ultra-wideband (UWB) technology and an asynchronous time difference of arrival (TDoA) algorithm, systematic errors do occur. Theoretical estimation of these errors can be very hard to make. This study introduces a novel filtering algorithm for reducing the bias of position estimations, therefore increasing their accuracy. The problem is tackled for a two-dimensional IPS by formulating a debiasing filter using statistics of real data. Generalisation to the three-dimensional case should be straightforward.
