Make GPS Robust, Says AMS Report on Satellite Navigation and Space Weather

A new report by the American Meteorological Society (AMS) highlights the vulnerability of GPS-dependent critical infrastructures to disruptions caused by solar flares and other space weather events, and sets forth a series of recommendations for building robustness of the GPS service.

Entitled “Satellite Navigation & Space Weather: Understanding the Vulnerability & Building Resilience,” the report is based on a workshop organized by the AMS and held October 13–14, 2010 in Washington, D.C.

Humboldt-Tolyabe National Forest, Nevada USA
√ In the Pacific Northwest, in-car navigators often indicate “short cuts” through wilderness mountains—with tragic results. One victim survived 49 days before rescue in May. (Reports blamed GPS – not digital maps or wireless communication.) GPS.GOV straightens out misperceptions, for those who need a guardian angel, but just get a signal.

Keeping the Spoofs Out

The demand for techniques capable of authenticating the GNSS signals and detecting simulation attacks (spoofing) has increased exponentially in the last years, mainly targeted to financial and safety critical applications.

Associated proposals and developments addressing these issues focused on two different approaches: user segment authentication services that leveraged existing services in order to detect signal spoofing and that integrated signal authentication services into the GNSS system itself.
