1 Mar 2022: Localized Russian jamming of GPS signals in Ukraine has been detected by US forces in the region, but so far has not interfered with US support operations, according to Pentagon officials.

– Jamming has been detected as far out as the Black Sea by US reconnaissance aircraft, but the source stressed it hasn’t had any impact on mission capability.

– US Space Command spokesperson said, “There are no impacts to U.S. and Allied forces in Europe at this time.”

– Senior defense official told reporters today that the US suspects Russia has been holding back in utilizing its vast toolset for electronic warfare so far

– It’s unclear if the jamming has had an effect on Ukrainian operations in-country.

HawkEye 360, a geospatial analytics company noted continual and increasing GPS interference near Ukraine in the weeks leading up to the invasion.

– HawkEye 360 operates a constellation of satellites to monitor radio frequency signals and pinpoint their location. The firm demonstrated its ability to detect and monitor GPS interference last year and now sells related products.

– Shortly before the Russian invasion began analysts detected GPS interference north of Chernobyl.

– In November, HawkEye 360 also noted GPS interference near the border between pro-Ukrainian and Russian-backed forces in Luhansk and Donetsk regions. With publicly available information, the company confirmed that the operation of unpiloted aircraft in the region was disrupted by the interference.

The source of jamming could be the Russian R-330Zh “Zhitel”; the Organization for Security Cooperation in Europe’s Special Monitoring Mission to Ukraine (OSCE SMM) reported a sharp increase in R-330Zh “Zhitel” GPS jamming activity in eastern Ukraine in 2019.

– The R-330Zh has been a staple in Russian anti-UAV operations in eastern Ukraine since 2015…Although the R-330Zh at times has been caught operating alone, it is often spotted alongside other EW systems, possibly as part of mobile EW groups to counter drones.

Localized jamming of terrestrial GPS receivers – rather than jamming or cyber attacks on the 30 GPS satellites currently operated by the Space Force – has become almost routine, since the 1998 Kosovo war, in many of today’s conflict zones such as Syria. In 2021 the US issued a new policy, Space Policy Directive 7 (SPD-7), to improve GPS…and increasingly focus on making GPS signals more jam resistant, as well as improving cybersecurity.
