The Global Positioning System (GPS) is the most widely-used global navigation satellite system. GPS provides much more than navigation services and telling you where you are; it is also essential for the timing of the digital networks that comprise the critical infrastructures essential to our way of life. The Automatic Identification System (AIS) is essential for the situational awareness of vessels at sea and management by maritime authorities and regulators. Both GPS and AIS are subject to attacks where their signals are either spoofed or jammed. This talk will discuss some of the reasons for which these attacks are occuring and the geopolitical implications of such events.
