Abstract :
KOMPSAT-5 has a benefit of continuously conducting its mission in all-weather by loading a SAR (Synthetic Aperture Radar) payload. During IOT (In-Orbit Test) periods, calibration and validation campaign is performed to determine that bus and payload are working as expected. Differently the conventional corner reflector, active transponder has a capability to adjust internal gain to meet the pre-defined RCS. In this paper, design, integration and verification conducted as an effort to develop active transponder for KOMPSAT-5 mission were presented.
