Abstract
A system and method for determining the location of a mobile device. A first set of signals from a plurality of radio frequency (“RF”) sources may be received at a mobile device and then downconverted into a second set of signals. The mobile device may then time stamp the second set of signals and transmit the time stamped signals to a location determining system. The location of the mobile device may be determined at the location determining system as a function of the time stamped signals.
