GPS System Vulnerabilities

Found this information about how insecure GPS systems really are to external attack and compromise. Even rendering one device completely useless.

    These are attacks aimed at the ground-based differential signal transmitters.

    Even if someone successfully attacks and takes down the differential transmitters in some area, it will mean that end-users' navigation devices in that region will revert to their "default" precision: the precision provided by the satellite signal alone. This is perfectly sufficient for such purposes as navigation.

    Another story would be to maliciously and deliberately manipulate the differential signal in order to freely distort the positioning calculations made by end-users' navigation devices. But I haven't heard of such exploits yet.

    Agreed, but maybe not so good for the aircraft looking for the center of the runway, the surveyor shooting a property line or the tractor plowing a narrow furrow. :twisted:
