Recently, the time difference of arrival (TDOA) based position determination technique is broadly used in many kinds of real time locating systems. In contrast with other position determination methods, TDOA based localization technique has the strength that it is unnecessary to synchronize the time between each receivers. With at least three receivers which we know their position, we can obtain TDOA solution. In a position determination problem including TDOA method, the accuracy of the estimated position is one of the significant factors. In this paper, in order to compensate measurement error due to time delay of signal propagation, the recursive least square (RLS) method is used. The RLS method is an iterated technique of least square (LS) method. The accuracy and calculation speed of estimated solution are improved through this algorithm. Simulation results show the performance of the proposed algorithm.
