  • Abstract:
    In 2001, a Volpe Center study assessed the vulnerability of the transportation system to

    loss of the Global Positioning System (GPS).1 Subsequent to this assessment, the

    Secretary of the U.S. Department of Transportation initiated an examination of

    approaches to mitigating this vulnerability. One system-wide possibility is to modify

    plans for the existing LORAN system, which is currently scheduled to cease operations in

    2008, to serve as a back-up to GPS. Within the U.S. Department of Transportation,

    there is a concurrent activity to provide a technical assessment of LORAN’s capability to

    provide this mitigation. The purpose of this independent Volpe assessment is to

    complement the broader concurrent technical analysis of LORAN 3 by addressing the

    question, “Given the need to provide a GPS back-up, is enhanced LORAN more cost beneficial

    than not having LORAN?”
