A novel full centroid and Taylor cooperative positioning algorithm of ultra wideband( UWB) is proposed aiming at problem of big error of localization precision caused by NLOS propagation in indoor environment. The full centroid positioning algorithm that is not sensitive to localization error is used as the initial rough localization by using anchol point ranging data grouping operations
and then Centroid scheme and selecting the rough localization nodes are applied to coarse localization node preliminary optimization
and the optimized value as the Taylor initial value. Simulation results show that this method has superior positioning precision than Chan-Taylor and LSE-Taylor algorithm.
