Description:

• YAMAL 401 is a communications satellite that will enter service in early 2015 at 90 degrees east longitude, where it will hover over a fixed location on Earth to beam communications services across Russia and neighboring countries for Moscow-based Gazprom Space Systems.

Mission details:

• Yamal 401, a communications satellite for the Russian corporation Gazprom Space Systems, was launched into geostationary orbit by a Proton on Dec 16, 2014. The Briz stage reached -449 x 170 km x 51 deg at 0025 UTC, 171 x 173 km x 51.5 deg at 0031 UTC, 264 x 4996 km x 50.0 deg at 0141 UTC, and 383 x 35654 km x 47.7 deg at 0402 UTC.
  The Briz DTB drop-tank was jettisoned at 0404 UTC and the Briz/Yamal coasted to apogee, with a final burn at 0903 to 0916 UTC delivering Yamal to a 1421 minute GEO drift orbit. The DTB is being tracked in a 402 x 35534 km x 47.6 deg orbit as 40345.
