Chapter 21: Space & SATCOM EW
The EM part of counterspace: the three satellite segments, uplink vs downlink jamming, spoofing/meaconing and dazzling, SATCOM jamming in Ukraine (with the Russian Starlink jammer Peresvet-M as a case study), and protection through spread spectrum and spot beams. GNSS warfare (§14) as a special case.

21.1Introduction: the spectrum reaches into space
Modern operations lean heavily on satellites: for communications ( SATCOM ), imagery (ISR), warning and navigation (GNSS, GNSS and navigation warfare ). That dependence makes space a target — and its electromagnetic part is the EW…

A satellite system consists of three parts, each with its own vulnerabilities:
Read §21.2 →21.3Uplink vs downlink jamming
You can jam a satellite link at the satellite — then it affects everyone in its coverage area — or close to the user, and then only that area.
Read §21.3 →21.4A current example and protection
The rise of commercial SATCOM (broadband via LEO constellations) on the battlefield in Ukraine ( Counter-UAS & drone EW ) has made jamming of SATCOM terminals an everyday reality — a new round in the age-old arms race, this time in space.

The SATCOM struggle in Ukraine ( A current example and protection ) became asymmetric in 2026. At the beginning of February 2026 Starlink was cut off for Russian units, after Ukraine introduced mandatory registration of terminals (through…
