2023-005-Various-GPS Interference & AIS Spoofing

Description

This advisory cancels and updates U.S. Maritime Advisory 2022-010

 

  1. Reference: None.

 

  1. Issue: Instances of significant GPS interference have been reported worldwide in the maritime domain. This interference can result in lost or inaccurate GPS signals affecting bridge navigation, GPS-based timing, and communications equipment (including satellite communications equipment). Over the last six months, an area in which multiple instances were reported was the Strait of Hormuz. The U.S. Coast Guard Navigation Center (NAVCEN) webpage, https://navcen.uscg.gov/gps-problem-report-status, contains a chronological list of recently reported GPS problems.

 

Additionally, Automatic Identification Systems (AIS) are open, unencrypted, and unprotected radio systems intended to operate on non-secure VHF-FM channels. As such, AIS signals can be spoofed, resulting in incorrect or missing AIS data.
