GPS Jamming in Maritime News
The digital global position signals (DGPS) that maritime vessels are equipped with today are accurate within a meter of actual location, but these devices are sensitive and research has revealed that the signal is easily disrupted.
According to research from the University of Nottingham and Royal Norwegian Naval Academy, who are investigating cyber-attacks involving marine GPS Jamming, findings show discrepancy up to 10 meters and that could easily result in an accident. These jamming devices can be purchased for less than $100.
Further, they find that by combining existing DGPS L1 receivers, which are used by many vessels, with a milt-frequency GLONASS receiver can reduce the chance of the vessels GPS getting jammed.
