Kompsat 1
1999-070A
The Korean Aerospace Research Institute (KARI)'s Korean Multipurpose Satellite will carry a TRW ocean color sensor with 6 bands and a spatial resolution of 1 km. It was launched by OSC Taurus in 1999. The 3-axis TRW Lightsat bus is hexagon + 2 panels 1.33 x 2.13m with 510 kg mass. Propulsion system is monopropellant hydrazine, 73 kg fuel. Orbit will be 685 x 685 km x 97 deg, 1050AM SSO. The satellite is built in Taejon, Korea with support from TRW/Redondo Beach. TRW built a full-up STEP class flight model which Korea then copied.
The satellite was renamed Arirang-1 after launch.
Launch mass 510 (464?) kg. Stage 3 is 1.96m x 1.60m, 381 kg; APC is 35 kg, 0.66 x 1.27m The TRW bus is also known as T-200.
Payload mass: 510 + 110 + 35 = 655 kg. Stage = 900/381

JCSAT-5
1997-075A
Japan Satellite Systems' JCSAT 5 (JCSAT 1B) is an HS-601, to be at 150E. Launch by Ariane in Dec 1997. JCSAT 5 was launched atop the Cyclade adapter covering the Equator-S science satellite. Provide communication services for Japan and the Asia-Pacific region.
Mass is 2982 kg launch, 1819 kg BOL, 1308 kg dry. Size is 3.80 x 2.80 x 4.30 m with 26.2 m span.
Info on LAM burns provided by Jun Takei of the JCSAT control center in Yokohama.
In 2005 JCSAT 5/1B had thruster problems which pushed its pointing off-target, and it was replaced by JCSAT 4.

Arabsat 4A
2006-006A
EADS Astrium Eurostar 2000+ satellite; 4B to follow. Launch by ILS Proton 535-11/Briz M 88515 Comms payload by Alcatel. Also called BADR-ONE.
Briz-M failed in transfer orbit; MES-2 ended 3min10s early. Planned duration was 21 min. Since the satellite contract was for on-orbit delivery, the satellite was presumably owned by Astrium in orbit. After the failure, a European insurance group took ownership (J. Oberg, http://www.nbcnews.com/id/11999597/ns/technologyandscience-space/t/arabsat-bites-dust-dashing-hopes)
Mass 3341 kg full 1520 dry 2.5 x 1.8 x 2.9m with 7.5 x 32.0 x 4.5m deployed.
