Study says GPS is vulnerable to disruption

The Global Positioning System is susceptible to unintentional disruption from atmospheric effects and communications equipment, as well as deliberate disruption, a study released Sept. 10 said.

The Transportation and Defense departments sponsored the study, Vulnerability Assessment of the Transportation Infrastructure Relying on the Global Positioning System, to determine the vulnerability of U.S. transportation that relies on GPS.

The study recommended:

  • Informing the aviation, maritime and surface user communities about GPS' vulnerability

  • Implementing systems to monitor, report and locate unintentional interference to GPS

  • Assessing the potential for civilian use of military GPS technology

  • Identifying and developing low-cost backup systems for GPS

  • Continuing the GPS modernization program.

    Transportation will hold a public meeting on the GPS study next month.
