ABSTRACT:
A method, apparatus, and computer-readable media comprise receiving a broadcast digital television signal comprising data relevant to one or more particular locations; generating a pseudorange based on the broadcast digital television signal; and determining location of an apparatus based on the pseudorange and a location of a transmitter of the broadcast digital television signal, and selecting a portion of the data relevant to the one or more particular locations based on the determined location of the apparatus.
