Abstract

For the improvement of accuracy and efficiency of indoor positioning in complex environment, this paper proposed a new positioning method, which combined Ultra-Wide Band (UWB) based on time difference of arrival (TDOA) with linearized Kalman filters (KFL-TDOA), in order to obtain more accurate and stable positioning results. On this basis, two classic location algorithms, Chan and Taylor series expansion algorithm, were integrated to get lower Root Mean Square Error (RMSE) and better anti-interference performance under non-sight-of-light (NLOS) and multipath effect, compared with using them separately. The proposed method considered interference both in ranging phase and positioning phase caused by complex indoor environment. Simulation case studies were conducted to demonstrate how the proposed method was implemented and the simulation results showed that compared with traditional TDOA based positioning method, the proposed method has improvement in positioning accuracy and stability both in ideal environment and interference environment if the parameters were set reasonable.
