Russian communications satellite. The Yamal communications satellite bus was developed by RKK Energia for Gazprom.

Status: Operational 1999. First Launch: 1999-09-06. Last Launch: 2014-04-16. Number: 5 . Gross mass: 1,360 kg (2,990 lb).

Due to their compact size and low mass, Yamal spacecraft could be launched two at a time by a Proton booster.

Initial plans were to deploy two vehicles, one at 75 degrees E and one at 19.50 West, in a 1997 launch. This was delayed to 1999, but they were successful and followed by a second pair in 2003. Yamal was the smallest of the proposed post-Soviet geosynchronous spacecraft with a total mass of 1.3-1.4 metric tons, including a payload mass of up to 310 kg. The box-like spacecraft bus carried two solar arrays capable of producing 2.4 kW at the end of the 10-year design life. A single primary dish antenna supported the nine planned C-band transponders. A combination of liquid and ion engines were used for spacecraft attitude and orbit maintenance. The spacecraft as finally flown was equipped with 12 C-band transponders built by Space Systems/Loral and Fakel SPD-70 plasma thrusters for inclination control.

1999 September 6 - . 16:36 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/23. LV Family: Proton. Launch Vehicle: Proton-K/DM-2M.
  • Yamal 101 - . Mass: 1,360 kg (2,990 lb). Nation: Russia. Agency: AO Gazco. Manufacturer: Korolev bureau. Class: Communications. Type: Civilian communications satellite. Spacecraft Bus: KAUR-4. Spacecraft: Yamal. USAF Sat Cat: 25896 . COSPAR: 1999-047A. Apogee: 36,298 km (22,554 mi). Perigee: 35,503 km (22,060 mi). Inclination: 2.4000 deg. Period: 1,441.90 min.

    The first two Yamal communications satellites were placed into a 197 km x 36,311 km x 49.3 degree transfer orbit The DM-2M fourth stage made two successful burns, placing the satellites in circular 36,000 km geosynchronous orbits. Yamal 101 reportedly ran into problems after it was deployed. RKK Energia built the new Yamal satellites for AO Gazcom of Moscow, a joint venture of RKKE and RAO Gazprom, the Russian natural gas monopoly. The two satellites will support internal communications for RAO Gazprom. Positioned in geosynchronous orbit at 89 deg E in 1999. As of 30 August 2001 located at 112.86 deg E drifting at 1.484 deg W per day. As of 2007 Mar 10 located at 42.96E drifting at 1.484W degrees per day.
