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.

There has been a massive American military buildup in the region in recent months, including the U.S. Navy's largest aircraft carrier, at least eight other warships, and F-35 aircraft.
The administration of U.S. President Donald Trump has bombed boats allegedly carrying drugs that have departed from the shoreline of Venezuela and other Latin American countries.
Direct flights by U.S. passenger or cargo carriers to Venezuela have been suspended since 2019 but some U.S. airlines fly over the country for some South American flights.
American Airlines (AAL.O), opens new tab said on Friday it had stopped overflying Venezuela in October. Delta Air Lines (DAL.N), opens new tab said it had stopped flying over Venezuela "a while ago." United Airlines (UAL.O), opens new tab did not immediately comment.
The order requires U.S. airlines to provide the FAA with at least 72 hours advance notice of planned flights but stopped short of prohibiting flights over the country.
The FAA said since September there has been an increase in Global Navigation Satellite System interference in Venezuela, which in some cases caused lingering effects throughout a flight, as well as "activity associated with increasing Venezuela military readiness."
"Venezuela has conducted multiple military exercises and directed the mass mobilization of thousands of military and reserve forces," the FAA said, adding that at no point had Venezuela expressed an intent to target civil aviation.
The agency said the Venezuelan military possessed advanced fighter aircraft and multiple weapons systems capable of reaching or exceeding civil aircraft operating altitudes, and there was potential low-altitude risk from air defense systems and anti-aircraft artillery.
The FAA said it will continue to monitor the risk environment for U.S. civil aviation operating in the region.
