What’s new: The US Federal Aviation Administration (FAA) issued an advisory yesterday about “WORSENING SECURITY SITUATION AND HEIGHTENED MILITARY ACTIVITY IN OR AROUND VENEZUELA…” Not mentioned in the advisory, but cited by many media outlets, is that detected interference with GPS in the area has increased significantly since September. 

Why it’s important:

  • High levels of GPS interference are often associated with military conflict zones.
  • Degraded GPS has been associated with aviation and maritime accidents.

What else to know:

  • Much of the interference seems to be coming from off-shore of Venezuela. 
  • Most recently it seems to be coming from the ocean near Trinidad and Tobago where U.S. Navy ships are said to be operating.
  • GPS-wise, it looks like the warning should be for Trinidad and Tobago…
  • GPS jamming and spoofing can be protective measures. After an attack on Venezuelan President Maduro by two explosive laden drones in 2018, Moscow began spoofing GPS in the vicinity of the Kremlin and other locations to deter surveillance and attack by drone on Russian officials.
