COSMOS 2417 (GLONASS), 28917

Orbit data source: Space-Track

COSMOS 2417 (GLONASS), 28917 is a Commonwealth of Independent States-origin payload satellite in MEO that was launched on Sun, 25 Dec 2005 UTC via a PROTON-K/DM-2 launch vehicle from the Tyuratam Missile And Space Complex (TTMTR). Payload-class satellites include a variety of spacecraft equipped with specific instruments for various scientific and technological missions. These include communications satellites like Starlink; space stations such as the ISS; scientific satellites like the Hubble; Earth observation satellites from companies like Planet Labs, Umbra, and HawkEye 360; GPS; miniature CubeSats for education and research; and military/defense satellites.
