Design and implementation of KSLV-I telemetry system with MIL-STD-1553B

KSLV (Korea Space Launch Vehicle)-I is under development to place a 100-kg class satellite into a low earth orbit of 300/spl times/1500km. KSLV-I telemetry system will be composed of two telemetry streams: a lower (first) stage telemetry stream and an upper (second) stage telemetry stream. Different from the previously developed telemetry system by KARI for KSR (Korea Sounding Rocket) series, the new telemetry system has been required to meet the enhanced requirements on telemetry system. This paper introduces a new development of telemetry system for KSLV-I upper stage telemetry with MIL-STD-1553B data bus emphasizing on the design, implementation, evaluation test and salient features of the telemetry system.
