Abstract

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

본 연구는 디지털위성중계기용 성능입증장치의 설계 및 구현에 대해 기술하였다. 성능입증장치(EGSE : Electrical Ground Support Equipment)는 디지털위성중계기를 평가하는 장비로 정밀하고 정확한 측정이 요구된다. 성능입증장치는 디지털위성중계기를 검증하기 위하여 위성버스를 모사한 PLDIU(Payload Distribution and Interface Unit)와 계측장비연동장치, SHF대역 상향주파수/하향주파수 변환장치, 모뎀 등으로 구성되어 있다. 성능입증장치는 디지털위성중계기를 제작 후 성능확인 및 열진공시험 등의 우주환경시험 시 활용하였다.
