2001 March 8

Launch Site: Kourou. Launch Complex: Kourou ELA3. LV Family: Ariane 5. Launch Vehicle: Ariane 5G.
  • BSAT-2a - . Mass: 3,050 kg (6,720 lb). Nation: Japan. Agency: BSAT. Manufacturer: Cannes. Program: BSAT. Class: Communications. Type: Civilian communications satellite. Spacecraft: Star bus. USAF Sat Cat: 26720 . COSPAR: 2001-011B. Apogee: 35,807 km (22,249 mi). Perigee: 35,764 km (22,222 mi). Inclination: 0.10 deg. Period: 1,436.10 min.

    BSAT-2a was a Japanese geosynchronous communications spacecraft and the second Orbital STAR-class television broadcasting satellite. Its launch mass was 1317 kg; dry mass was 535 kg. The satellite had a Thiokol Star 30CBP solid apogee motor. The new BSTAR STAR-class satellites are a new design replacing the earlier Starbus type satellite of which only one (Cakrawarta 1) was launched. BSAT Corp. (Broadcasting Satellite System Corp.) earlier launched HS-376 satellites BSAT 1a and 1b, replacing the government's BS series which began Japanese direct broadcast services in 1978. The satellite was to be parked over 110 deg-E longitude to provide direct-to-home voice, video and internet communications. Positioned in geosynchronous orbit at 110 deg E in 2001 As of 5 September 2001 located at 109.82 deg E drifting at 0.018 deg W per day. As of 2007 Mar 11 located at 109.92E drifting at 0.009W degrees per day.

2001 July 12

21:58 GMT - . Launch Site: Kourou. Launch Complex: Kourou ELA3. LV Family: Ariane 5. Launch Vehicle: Ariane 5G.
  • BSAT-2b - . Mass: 3,105 kg (6,845 lb). Nation: Japan. Agency: BSAT. Manufacturer: Alenia. Program: BSAT. Class: Communications. Type: Civilian communications satellite. Spacecraft: Star bus. Decay Date: 2014-01-28 . USAF Sat Cat: 26864 . COSPAR: 2001-029B. Apogee: 17,400 km (10,800 mi). Perigee: 659 km (409 mi). Inclination: 2.90 deg. Period: 317.20 min.

    BSAT-2b was planned as a geosynchronous television broadcast satellite for the Japanese B-SAT company. It used Orbital's Star 1 bus and had a launch mass of 1298 kg. It carried a Thiokol Star 30 solid apogee motor and a set of station-keeping thrusters with 200 kg of propellant. A propulsion problem in the final stage of rocket stranded the satellite at a much lower altitude than planned. Since BSAT 2B carried only a soild propellant apogee kick motor, it was unable to maneuver itself to a useful orbit.
