Russia has accelerated its jamming of global positioning system (GPS) satellites around Moscow, apparently to deter long-range strikes by Ukrainian drones, according to the GPSJam monitoring website.
The ramp-up followed drone strikes on two Russian airbases earlier this month, says Dana Goward at the Resilient Navigation and Timing Foundation, Alexandria, VA. Russia has jammed satellite navigation following drone strikes before, and it has various military mobile jamming systems that broadcast radio noise to disrupt weak signals. Operators directly pilot short-range drones, making GPS use unnecessary. However, long-range strikes generally need GPS to navigate, so jamming would thwart remotely orchestrated strikes.
Jamming won’t protect against all drones, however. Shahad-136 drones, for example, which Russia has used against Ukraine, are equipped with navigation units that allow them to pass through areas of jamming.
