Abstract

Accurate estimation of signal arrival time is essential in many applications, such as time-based wireless and indoor location systems. In this paper, a novel time of arrival (TOA) estimation algorithm for ultra-wideband (UWB) system is proposed, which is based on unitary-ESPRIT algorithm. Following this, a UWB-based lunar rover localization method is then proposed using exact time-of-arrival measurements on the lunar surface. The simulation results show that the proposed TOA estimation method is superior to conventional methods, and the accuracy of lunar rover positioning is in centimeter level.
