A New Simple and Fast Algorithm for the Position Estimation Based on TOA

Mobile station position have been receiving more and more attention in recently years. Positioning via time of arrival is a kind of key technology. A simple and fast algorithm based on time of arrival technology is proposed in this paper. Through the first step estimation, we can easily get the rough value by changing the coordinate origin. And the precise value will be got through the second step estimation. The simulation results show that the estimation based on this method has excellent ability approached to CRLB.
