In this paper, we propose a modified two stage Taylor series (TS) method for position estimation in a 3-D environment when either the time-difference-of-arrival (TDOA) or the distance measurements are available. It is aimed to improve the convergence performance of the traditional Taylor series method. Simulation results demonstrate that the modified TS method can improve the position estimation convergence...
This work deals with the development of pre-filtering techniques for low-cost devices using high data rate communications. Many positioning algorithms have been recently revisited in a centralized architecture scenario, where a cheap mobile sensor is surrounded by N base stations. The overview of the system is composed of two blocks: a smoothing filters and a positioning block. In the smoothing filters...
