ABSTRACT:
A computer program product, apparatus, and method for determining the position of a user terminal. It includes receiving, at the user terminal, a broadcast analog television signal having a periodic component; and correlating the broadcast analog television signal with a predetermined reference signal based on the periodic component, 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.
