Technical Aspects of The Japanese Broadcasting Satellite Experiments

After a successful launch of the Japanese Medium-Scale Broadcasting Satellite for Experimental Purpose (BSE) "Yuri" in April 1978, check-outs of the satellite and the transponder were conducted by the National Space development Agency of Japan (NASDA) for three months. In July, Radio Research Laboratories (RRL) of the Ministry of Posts and Telecommunications (MOPT) and Nippon Hoso Kyokai (NHK: Japan Broadcasting Corporation) initiated various kinds of satellite broadcasting experiments which will be continued for three years. This paper presents brief description of the BSE program and the preliminary results of the experiments.
