RADIO ROSTO (RS15) — Live Satellite Tracking (NORAD 23439)
Track RADIO ROSTO (RS15) (NORAD catalog number 23439) live on the WatchSat interactive 3D globe above. Its position is propagated in real time from the latest CelesTrak two-line element set using the SGP4/SDP4 orbital model — the same math professional trackers run. It has been on orbit since 1994, launched on the 85th orbital launch of that year (COSPAR designation 1994-085A).
Moving at about 7.00 km/s, RADIO ROSTO (RS15) operates in medium Earth orbit at roughly 1,895–2,164 km altitude, taking about 2.1 hours per revolution (11.28 orbits a day). The orbit is essentially circular (eccentricity 0.0160). Inclined 64.8° to the equator, it overflies every latitude up to about 65° north and south. Its orbital plane crosses the equator northbound at right ascension 99.5°. Earth's equatorial bulge drifts that plane westward about 1.62° per day.

Can you see RADIO ROSTO (RS15) from the ground?
Not with the naked eye. At its altitude RADIO ROSTO (RS15) is far beyond unaided visibility — following satellites this high takes a telescope and good timing. You can still track it precisely in the live 3D view above, or check the “When can I see it?” panel in the live view.
