Program: BONUM. Objective: Communications. Overview: BONUM satellites provide domestic Russian television service for Media Most, a Moscow media enterprise. Major Events: - 1998 November 22 - BONUM-1. Spacecraft: HS 376. Launch Site: Cape Canaveral. Launch Vehicle: Delta.
BONUM-1 provided domestic Russian television service for Media Most, a Moscow media enterprise, broadcasting 50 channels to western Russia from a geostationary orbit at 36 degrees E. Mass was 1426 kg at launch, 800 kg of that propellant. BONUM-1 carried 8 Ku-band transponders. The Delta upper stage raised the initial 157 km x 189 km at 29.2 degree parking orbit to 159 km x 1304 km and then 1228 km x 1683 km at 26.7 degrees. A Thiokol Star 48B solid third stage boosted BONUM-1 to a 1285 x 36703 km x 19.5 degree geostationary transfer orbit, with the Thiokol Star 30 apogee kick motor placing the satellite in its final geostationary orbit. After separation of the spacecraft, the Delta made a final depletion burn to lower its orbit to 274 km x 1552 km x 25.6 degree to ensure it would quickly decay and burn up in the atmosphere. Geostationary at 35.9 degrees E. From 8 August 2000 position was 56.0 degrees E. Positioned in geosynchronous orbit at 36 deg E in 1998-1999 55 deg E in 2000. As of 5 September 2001 located at 56.03 deg E drifting at 0.016 deg W per day. As of 2007 Mar 10 located at 55.94E drifting at 0.008W degrees per day.
