Kalinka

Russia's most-discussed answer to Starlink is not a jammer. Kalinka listens for the uplink signal a terminal sends to the satellite, isolates it from background noise, and works out where the operator is sitting — converting a communications link into a targeting cue.

Overview

Kalinka is a Russian passive signals-detection and direction-finding system developed by Rossiysky Kupol (Russkiy Kupol) and reported operational since late 2024. Its function is frequently misdescribed: it does not jam. It receives and analyses the uplink emissions that a Starlink user terminal transmits toward the constellation, isolates those emissions from the surrounding radio-frequency environment, and determines the direction and location of the emitter.

That distinction matters operationally. A jammer denies a service in an area and announces itself doing so. Kalinka produces a coordinate. In a war where Ukrainian drone crews, naval drone operators and command nodes depend on Starlink for connectivity, a system that turns terminal use into a geolocation is a targeting sensor feeding artillery, drones and strike aviation — not a communications-denial tool.

The developer claims detection and direction-finding of active Starlink terminals at up to 15 km under line-of-sight conditions, including the militarised Starshield variant. That figure is contested, and the contest is covered in detail below.
