Robust Navigation and Communication in the Maritime Domain: The TRITON Project

Intentional jamming and spoofing are growing concerns for communication and positioning systems based on Global Navigation Satellite System (GNSS). In the maritime sector, intentional interfering signals might induce poor performance of the GNSS receivers, that, in severe cases, are unable to provide reliable measurements. On board of vessels, the failure of the GNSS receiver propagates to multiple systems, like the Automatic Information System (AIS) transponder, the ship´s gyro calibration system and the digital selective calling system. The AIS itself can suffer from failures due to interference in the VHF band, and the lack of bandwidth makes it difficult to introduce security any security mechanisms. The vulnerability to intentional interference as well as the availability of personal privacy devices easily sold over the Internet motivate attackers who intend to fraud services and get direct benefits.
