Russia has figured out how to jam U.S. drones in Syria, officials say
The US and NATO have been closely monitoring Russian SIGINT in eastern Ukraine for about two years now. The consensus is that the Kremlin is far ahead of previous assessments regarding most facets of electronic warfare.

WASHINGTON — The Russian military has been jamming some U.S. military drones operating in the skies over Syria, seriously affecting American military operations, according to four U.S. officials. The Russians began jamming some smaller U.S. drones several weeks ago, the officials said, after a series of suspected chemical weapons attacks on civilians in rebel-held eastern Ghouta. The Russian military was concerned the U.S. military would retaliate for the attacks and began jamming the GPS systems of drones operating in the area, the officials explained. Jamming, which means blocking or scrambling a drone's reception of a signal from a GPS satellite, can be uncomplicated, according to Dr. Todd Humphreys, the director of the Radionavigation Laboratory at the University of Texas at Austin. "GPS receivers in most drones can be fairly easily jammed," he said
Humphreys, an expert on the spoofing and jamming of GPS, warns this could have a significant impact on U.S. drones, causing them to malfunction or even crash. "At the very least it could cause some serious confusion" for the drone operator on the ground if the drone reports an incorrect position or is lost, he said. U.S. analysts first caught the Russian military jamming drones in eastern Ukraine four years ago, after the invasion of Crimea, according to Humphreys. The officials said the equipment being used was developed by the Russian military and is very sophisticated, proving effective even against some encrypted signals and anti-jamming receivers. The drones impacted so far are smaller surveillance aircraft, as opposed to the larger Predators and Reapers that often operate in combat environments and can be armed. Dr. Humphreys says that though the attacks occur in cyberspace, the results are still serious. "They are a little less hostile looking than a kinetic bullet but sometimes the effect can be just as damaging," he said. "It's like shooting at them with radio waves instead of bullets."
