GPS interference and jamming on the increase

Text and photos by gard

Ships have reported an increasing number of cases of significant GPS interference and jamming in recent months. The geographic areas with more than one reported incident include the eastern and central Mediterranean Sea, the Persian Gulf, and multiple Chinese ports. This interference and jamming have resulted in loss of or inaccurate GPS signals and has affected vessels’ navigation and communication equipment.

Whilst at sea, exact position, speed, and heading are essential to ensure safe navigation. The need for exact position information is particularly important when a vessel navigates close to shore or departs or arrives in port.

US advisories

On 24 September 2020, The US Department of Transportation’s Maritime Administration Advisories (MARAD) issued an alert 2020-016-Various-GPS Interference covering multiple instances of significant GPS interference reported worldwide in the maritime domain.

Similarly, The US Coast Guard’s Navigation Center (NAVCEN) investigates reports of GPS interference by civil, non-aviation GPS users and researches these reports and, if possible, establishes the mostly likely cause. In the bulk of reported GPS interference instances in the years 2017-2019, 37 were reported by vessels operating in the Mediterranean Sea, with 22 of those reported in the vicinity of Egypt. In addition, 2 instances were reported in the Black Sea (Odessa, Ukraine and Novorossiysk, Russia). Furthermore, there were 1 instance reported in Hodeidah, Yemen, 1 in the Strait of Hormuz and 2 in the port of Jeddah, Saudi Arabia. The reported locations are shown as red dot on the map above.

During the same period, there were also a number of instances of GPS interference reported in China; 4 in the vicinity of Shanghai in Eastern China, 1 in the vicinity of Qingdao in Eastern China, and 1 in the vicinity of the Sea of Japan.

In my announced sequel, the second part of GPS, it is primarily about the technical and physical operational and functional limitations to which GPS is subject. These limitations, in part, have serious implications for the accuracy of GPS, and even go as far as limiting the functionality of GPS in its functions or even making it impossible. In doing so,
