Abstract

See full text

A system and method involve using sferic signals to synchronize clocks and/or determine relative receiver positions within a communications network. A sferic signal is detected, encoded, and then identified. A time-difference-of-arrival (TDOA) for the sferic signal is then calculated. A clock error estimate is determined from the TDOA. The clock error estimate is then used to synchronize clocks and/or determine relative receiver positions.
