Abstract
A method and apparatus for circumventing jamming of receivers for a global positioning system (GPS) include determining that a receiver is being jammed by a jamming signal not originating from the GPS. A first signal is transmitted from a portable unit including the receiver to a component of a second positioning system that is different from the GPS. A second signal is received from the second positioning system. The second signal includes data that indicates a position for the portable unit determined in the second positioning system based at least in part on the first signal.
