Abstract:
A method, apparatus, and computer-readable media for determining the position of a user terminal comprises receiving at the user terminal a digital television (DTV) broadcast signal from a DTV transmitter, wherein the DTV signal comprises an Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) signal; determining a pseudo-range between the user terminal and the DTV transmitter based on a known component in the broadcast DTV signal; and determining a position of the user terminal based on the pseudo-range and a location of the DTV transmitter.
