Russian Kosmos 2612 and ICEYE-X36 (providing Ukraine military support) are now in perfect sync with each other. The Russian military satellite is intentionally stalking and tracking the Western radar satellite. Keeping a satellite "bumper-to-bumper" in this manner allows Russia to intercept or jam data transmissions, physically inspect Western technology, or quickly pivot to execute a kinetic or non-kinetic anti-satellite (ASAT) attack with very little warning or fuel expenditure.
Kosmos 2612 executed a series of highly precise, fuel-heavy maneuvers to force itself into a "coplanar" orbit—matching ICEYE-X36's exact altitude (~555 km), speed, and inclination (~97.8°). The ICEYE-X36 satellite is giving the Ukraine military support.
