Russian military satellite Cosmos 2612 has maneuvered to close in on ICEYE-X36 part of the ICEYE commercial SAR constellation, which supports Ukraine.
Launched from Plesetsk in April 2026, Cosmos 2612 has co-orbited ICEYE-X36 for months in essentially the same plane and altitude (Δi 0.00°, ΔRAAN 0.1°), then in late September raised its orbit, drifted, and dropped back to set up a close pass.
Closest approach today (2026-10-16): 4.5 km at just ~4 m/s.
A matched orbit set up by a deliberate maneuver is classic inspector behavior, not a random flyby.
Data: Space-Track + orbital analysis

Russian military satellite Cosmos 2612 has closed in on ICEYE-X36 — part of the ICEYE commercial SAR constellation, which supports Ukraine.
Launched from Plesetsk in April 2026, Cosmos 2612 co-orbited ICEYE-X36 for months (same plane & altitude: Δi 0.00°, ΔRAAN 0.1°), then maneuvered to close the gap: 4.5 km on 16 Oct → ~30 m at ~0 m/s on 18 Oct.
It’s now station-keeping repeated approaches, all within ~30 km.
A matched orbit at ~0 m/s is co-orbital inspection, not a flyby. (Sub-km miss is below public-tracking precision; the ~0 m/s match is the robust part.)

Caveat on that ~30 m: it’s inside the error bars. SGP4 from public TLEs is good to ~1 km, propagated ~15h past epoch — so 26 m is below the noise. Could be tens–hundreds of m. What’s solid: matched orbit at ~0 m/s. Whether 30 m or 300 m, it’s a deliberate co-orbital inspector.

The Russian satellite makes its closest pass to the ICEYE satellite high over the Arctic Ocean, north of Canada. The nearest speck of habitation is a Canadian research station CFS Alert ~280 km away; the nearest city (Anchorage) is ~2,700 km.
The red line (Russia’s Cosmos 2612) and the blue line (ICEYE-X36) look like one track because the two satellites are flying almost on top of each other within about 100 metres.
And remember: this is all ~550 km up in space. Nothing is happening on the ground the line just marks the spot directly beneath them.

Why would Russia fly a satellite right next to a radar satellite? The simplest answer: to study it up close.
SAR satellites like ICEYE’s downlink their imagery through polar ground stations. Svalbard (Norway), Inuvik (Canada) and Alaska chief among them. Because these satellites cross the poles on every orbit, they’re talking to those stations almost constantly.
A satellite flying in the exact same orbit is perfectly placed to watch all of it the radar emissions, the downlink timing, the RF signatures, the daily routine. In the trade it’s called pattern-of-life.
You don’t have to touch a satellite to learn a great deal about it. You just have to fly next to it which is exactly what Cosmos 2612 is doing, for now!!
