The Japanese Communications Satellite (CS), called Sakura, is a "Medium Capacity Communications Satellite for Experimental Purposes" and is the first experimental communications satellite in which 30/20 GHz bands were adopted and were developed for practical domestic use. Large scale field trials have been carried out for more than three years in order to evaluate 30/20 GHz (Ka-band) and 6/4 GHz (C-band) domestic satellite communications system technologies under actual operational conditions by using the CS Sakura launched in December 1977. Through the various experiments on Kand C-band large fixed and small transportable Earth station systems, satellite control experiments, and Ka-band propagation measurements, it has been verified that the medium capacity satellite communications system meets the design objectives.
