본 논문에서는 현재 KRISS(한국표준과학연구원)에 구축 된 JCSAT-1B 위성과 PAS-8 위성 그리고 PAS-4 위성을 이용하여 KRISS와 NICT(일본의 정보통신연구기관)간의 양방향 시각비교를 통하여 그들의 안정도를 비교분석하고 향후 JCSAT-1B 위성의 백업시스템으로써 PAS-4 위성과 PAS-8 위성의 활용성을 검토하였다.

This is a survey report of Japan's geo-stationary satellite development. Owing to Japanese government's ambitious space development efforts since 1950's, Japan became the fourth country that launched successfully its own satellite by using its own launch vehicle with the launch of Japan's first satellite, Ohsumi, in 1970. Since then Japan is maintaining a world leader's position in space development with continuous technology accumulation. Japan is injected 97 satellites into orbit(third in the world) by the end of 2003 including 18 science satellite series, 7 technology experiment satellite series, 5 meteorological satellites, and numerous telecommunication and broadcasting satellites, etc. With successful delivery of Optus C1 satellite to Sing Tel Optus Pty., Ltd. in Australia in June 2003 by MELCO, Japan is capable of competing in the international geo-stationary satellite market.
