Abstract :
This paper briefly reviews the literature on existence and uniqueness of localization using Time-Different-of-Arrival (TDOA) limited by 4 anchors. To overcome the incompleteness encountered by algebraic solution in finding the TDOA solution, this paper suggests several practical approaches to select the correct root. The architecture and measured performance of a 3D Ultra-Wideband indoor positioning system using TDOA based on the use of 4 anchors are also presented.
