Pulsar Navigation Using Time of Arrival (TOA) and Time Differential TOA (TDTOA)

Acta Astronautica, 2018
Abstract Pulsar navigation is a novel autonomous navigation method for deep-space missions. The pulsar navigation method using the time of arrival (TOA) determines the absolute position of the spacecraft. However, its accuracy is greatly affected by system errors, including the ephemeris error of the pulsar and the satellite-borne clock error.

Energy-Based TOA Estimation

IEEE Transactions on Wireless Communications, 2008
This paper investigates time of arrival estimation via impulse radio ultra-wideband technology. A dense multipath channel is assumed and frequency-selective propagation effects are taken into account that make the individual received pulses different in shape from the transmitted monocycles.

Scatterer Distribution Based on TOA/AOA and TOA/AOD

Journal of Convergence Information Technology, 2012
Abstract A data driven technique, bivariate kernel density estimator, is used to deduce the scatterer distribution in order to extract the true scatterer distribution in real mobile environment. Under the assumption of single reflection of signal, the TOA /AOA and TOA /AOD measurements are used to obtain the unknown position of the scatterers by means ...
