Abstract

Design issues of multi-beam satellite transponders have been actively studied. Multi-beam satellite transponders can be used in the first SS/TDMA system for satellite interactive multi-media services in Korea. To be used in SS/TDMA systems, a satellite transponder must have either base-band OBP(On-board Processor) or MSM(Microwave Switching Matrix) on-board switch those are capable to provide inter-connections to many earth stations in different beam coverages or different frequencies, i.e., Ka and Ku band. The use of MSM is considered proper due to a substantial developing cost and the required high techniques in base-band OBP. In this paper, we present a designed scheme of transponder being optimally suitable to the targeted SS/TDMA satellite systems, also analysis the performance.

현재 국내에서는 기저대역 처리에 소요되는 기술적 난이도와 개발에 수반되는 경제적 비용을 감안하여 MSM 스위치로 빔간의 상호연결뿐만아니라 Ku 대역과 Ka 대역간의 상호연결을 통해 위성 interactive 멀티미디어 서비스를 제공하는 SS/TDMA 위성 시스템에 대한 연구가 활발히 진행되고 있다. 본 논문에서는 이를 위한 SS/TDMA 위성시스템의 중계기 구조를 도출하고 분석한다.
