Abstract

COMS (Communication, Ocean and Meteorological Satellite) is the multi-purposed Korean geostationary satellite funded by four Korean government ministries, and is to supply communication services, ocean and weather observation for 7 years. As part of COMS, development of Ka band communication payload composed of microwave switching transponder and multi-horn antenna is sponsored by KCC (Korea Communications Commission) and developed by ETRI (Electronics and Telecommunications Research Institute). The purpose of Ka Payload development is to acquire space proven technology of Ka payload and to exploit advanced multimedia communication services. This paper aims to study development technology of Ka payload system through whole process of ETRI project. Also application of Ka payload will be dealt in this paper.

통신해양기상위성은 4개 정부부처 공동사업으로, 통신서비스, 해양기상 관측서비스를 7년간 제공하게 된다. 위성 스위칭 중계기와 다중빔 안테나로 구성된 Ka 통신탑재체 개발은 방송통신위원회 출연으로 ETRI 주관으로 개발하였으며, 통신탑재체 개발목적은 우주인증 기술확보와 차세대 멀티미디어 위성서비스 개발이다. 본 논문 목적은 통해기 통신탑재체 국산 개발사업의 전 과정을 통한, ETRI 의 Ka대역 통신탑재체 개발기술 연구이며, 또한 통신탑재체 응용 기술에 대해 다루고자 한다.
