📖 About This Object
COSMOS 1305 is an active satellite operated by Russia (CIS), launched on 1981-09-11 from PKMTR. With over 45 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Medium Earth Orbit (MEO) at altitudes between 565 km and 13,916 km with an inclination of 62.8°. It travels at approximately 19,481 km/h (5.41 km/s), completing one full orbit every 4 hours 24 minutes — that’s roughly 5.46 orbits per day. Its orbital eccentricity of 0.4904 gives it a noticeably elliptical path, with significant altitude variation between perigee and apogee. Orbital Radar tracks COSMOS 1305 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
COSMOS 1305 orbits at an average altitude of 7,241 km in Medium Earth Orbit, the region between LEO and GEO (2,000–35,786 km). MEO’s higher altitude gives each satellite a much larger ground footprint than LEO, meaning fewer spacecraft are needed for global coverage — but signal latency is higher and radiation from the Van Allen belts is a significant design constraint. Within ±50 km of COSMOS 1305’s average altitude, there are currently 1 active payload and 6 tracked debris or rocket body fragments. This is a relatively sparse altitude band, containing less than 1% of all active satellites. With an inclination of 62.8°, COSMOS 1305 passes over latitudes between 62.8°N and 62.8°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. Russia (CIS) operates approximately 1,285 active satellites in total.
🔗 Cosmos (Military/Government) Series
This satellite carries the Cosmos designation, used by Russia (and formerly the Soviet Union) as a generic identifier for military and government spacecraft. The Cosmos series encompasses reconnaissance, signals intelligence (SIGINT), early warning, navigation, communications and scientific payloads. Many Cosmos satellites have classified missions with limited publicly available information.

Yes — Orbital Radar tracks COSMOS 1305 (NORAD ID 12818) using the latest TLE (two-line element set) data from Space-Track and CelesTrak. Open the live tracker to see its current position, altitude, speed and orbital path updated in real time. You can also browse the satellite directory to find other tracked objects.
COSMOS 1305 travels at approximately 19,481 km/h (12,105 mph) — roughly 5.41 km/s. It completes 5.46 orbits per day, meaning the crew or instruments aboard (if any) would experience approximately 11 sunrises and sunsets every 24 hours.
