Abstract

A method, apparatus, and computer-readable media for determining the position of a user terminal comprises generating a correlation reference signal based on known characteristics of a chirp-type signal present in a broadcast analog television signal; receiving, at the user terminal (102), a broadcast analog television signal comprising the chirp-type signal; and correlating the broadcast analog television signal with the correlation reference signal, thereby producing a pseudorange; and wherein the location of the user terminal is determined based on the pseudorange and a location of the transmitter of the broadcast analog television signal.
