November 2025: Since mid-November, electromagnetic interference has descended on the Caribbean. Amid a U.S. military buildup in the area—including attacks on alleged drug-running boats—the U.S. FAA has issued a critical warning to commercial pilots. Many commercial aviation navigation systems still rely on the traditional L1 GPS signal now threatened by increased interference. “Aviation receivers are often 20 years old,” said the RNL’s Dr. Todd Humphreys. “L5 would be a big help here, given the wider band frequency.” Furthermore, according to Dr. Humphreys, GPS interference can affect satellites in LEO, such as the Starlink and OneWeb constellations.
Experts tie the jamming to military actions in the region, as modern naval fleets often employ GPS jamming in conflict. “A carrier strike group is susceptible to attacks from large swarms of drones,” Humphreys said, and is an important consideration to both Venezuelan and U.S. naval assets.
