Analytical geolocation and three-dimensional localisation by time difference of arrival
article
Geolocation based on time differences of arrival measured by three sensors is studied. Closed-form analytical solutions are derived, even for the cases where one or more sensors are not located on the earth. Exploiting four sensors, full three-dimensional localisation is achieved as well. These numbers of sensors are minimal. The analytical results have been
implemented in algorithms and tested by Monte Carlo simulations. The results are unbiased and comply with the theoretical Cramer–Rao lower bound.
