Russia released a large number of attack UAVs targeting Kyiv, Ukraine, in the early morning of June 20, reported the New York Times. The UAV attack on Kyiv was the first in several weeks after Russian forces repeatedly targeted the city throughout May.
The air-raid alert started in Kyiv around 3 a.m. local time and lasted for more than three hours, as UAVs came in waves from all directions. According to the New York Times, Ukraine’s Air Force said Russian forces had launched 35 Iranian-made UAVs around Kyiv.
Ukraine air defenses shot down 32 of the UAVs, which included more than a dozen near the capital.
On June 21, Reuters reported that Russian air defense had downed three UAVs in the Moscow region in what they believe to have been a Ukrainian attack. The Defence Ministry stated that Russian forces had used electronic jamming, which caused the UAVs to lose control and crash.
Reuters could not independently verify details of this incident or who had launched the UAV attack.
The Russian military has disrupted flight systems in three regions since the invasion of Ukraine, highlighting the need for robust alternatives, according to a French safety regulator and as reported by Bloomberg.
Airline pilots have reported jamming of satellite navigation systems around the Black Sea, eastern Finland and the Kaliningrad enclave, said Benoit Roturier, head of satellite navigation at France’s civil aviation authority DGAC.
The jamming signals appear to originate from Russian trucks intent on protecting troops and installations against GPS-guided missiles. While the signals are not aimed at civil aviation, however, they force the pilots to deal with distracting alerts.
“Airplanes hit by jamming can continue to fly using inertial navigation systems — that is standard and works with GPS,” Roturier said. “This could be less accurate, but can be used when GPS goes down.” Yet regulators are realizing the potential for massive airspace disruptions, especially as the European Union pushes for increasing reliance on satellite navigation.
Two recent reports from the Organization for Security and Co-operation in Europe (OSCE) have described a recent increase in GPS jamming, presumably by Russian or pro-Russian forces in Ukraine. This comes as Russia has increased its troop numbers and activity along its border with Ukraine.
OSCE is charged with a Special Monitoring Mission (SMM) in Ukraine which observes and reports on how well both sides are adhering to the Minsk Protocol agreement. The agreement was signed in September 2014 by participants in the conflict in an effort to end open hostilities.
One of the ways the OSCE mission monitors activity and compliance in the region is with long range UAVs. As early as November 2014, the organization reported UAV operations being thwarted by interference with GPS signals.
Two recent OSCE spot reports have highlighted a resurgence in jamming.
An April 7 report described interference that prevented a UAV takeoff the previous day. While the organization’s UAVs had been experiencing increased interference since March, this was the first time since October 2014 that it had thwarted a mission before takeoff.
The report also documented an increasing level of jamming activity.
“Over the last two months, 62.5 percent of SMM long-range UAV flights encountered GPS signal interference and on 75 percent of the affected flights it occurred more than once.”
A second report on April 9 outlined continuing problems that caused missions to be aborted. It emphasized that this was a violation of the agreement signed by all parties and greatly hampered OSCE’s mission.
“Any GPS signal interference hinders the Mission’s ability to conduct effective monitoring and reporting of the security situation in line with its mandate. Long-range UAVs are an essential part of SMM operations, especially at night and in areas where the Mission’s monitoring and freedom of movement are restricted.”
GPS jamming and spoofing are important parts of Russia’s arsenal to counter any technological advantage the west may have over their forces. A 2015 Sputnik article bragged their electronic warfare kept U.S. cruise missiles from hitting their targets at the start of the 2003 invasion of Iraq. Also, that this advanced capability “renders aircraft carriers useless.”
Interference with GPS signals is a regular feature of Russian military and internal security operations.
The United States has formally expressed concerns about the recent increase in the number of Russian troops and their activity at the Ukrainian border. It has been reported that two U.S. Navy ships are on their way to the Black Sea to help monitor the situation.
