Vessel hit by GPS interference near the Port of Jeddah in Saudi Arabia

Summary:

In October 2018, vessels got hit by a GPS interference near the Port of Jeddah in Saudi Arabia. Before departure from port of Jeddah Saudi Arabia in Red Sea both GPS were found out of order. There seemed to be GPS signal interference resulting in loss of signal, missing COG / SOG and absence of GPS signals affecting bridge navigation and other communication equipment. The GPS screen showed no available satellites in the vicinity, no Lat/Long could be obtained. Another vessel lost GPS Signal on all nodes while they were approaching the Jeddah Port on 15/10/2018, 0530z. They checked with the out bound vessels and they too did not have GPS Signals. It is believed that it was jammed.
