초록

본 연구는 대전자전 중계기용 성능 입증 장치의 설계 및 구현에 대해 기술하였다. 성능 입증 장치(EGSE :Electrical Ground Support Equipment)는 대전자전 중계기를 평가하는 장비로 정밀하고 정확한 측정이 요구된다. 성능 입증 장치는 대전자전 중계기를 검증하기 위하여 위성 버스를 모사한 PLDIU(Payload Distribution and Interface Unit)와 계측장비 연동장치, L대역 상향주파수/하향주파수 변환장치, 모뎀 등으로 구성되어 있다. 성능 입증 장치는 대전자전 중계기를 제작 후 성능 확인 및 열진공시험 등의 우주 환경 시험 시 활용하였다.

This study describes the design and implementation of EGSE for Dehop/Rehop Transponder. The EGSE is a equipment that evaluates Dehop/Rehop Transponder and requires precise and accurate measurement. EGSE consists of a PLDIU and IIU(Instrument Interface Unit), Up/Down converter for L band, Modems to verify the Dehop/Rehop Transponder. The EGSE was used for performance verification and space environment test such as thermal vacuum after developing Dehop/Rehop Transponder.
