In order for a gps jammer to work, it must be close enough to the signal its team wants to jam. On the other hand, according to jammer-mart, an independent think tank dedicated to military electronic systems, high-power GPS drone gun jammers can detect targets dozens of miles away. Interference requires more power than detection, so the distance that Avtobaza can interfere with drones must be less than 90 miles.
This is why Russian drone jammers and the new "special forces" anti-drones that operate them do not necessarily pose a survival risk to U.S. military drones. Russian GPS signal jammers may find it difficult to find targets. A former U.S. drone developer, who asked not to be named, said: "Unless you know where they are and when, it seems difficult to do it."
GPS stoppers are not limited to interference. Increasing reports indicate that the Russians have expanded their ability to deceive system signals, placing point receivers in the wrong place. In June 2017, we reported a report from the U.S. Maritime Administration on such incidents in the Black Sea, where the ship's navigation equipment indicated its inland location. Previously, in Moscow, players of the popular Pokemon Go mobile game also reported other location errors that relied on GPS signals from mobile devices to interfere with location services.
