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
