Japanese domestic satellite communications systems experiments

The Japanese program involving the medium-capacity communication satellite for experimental purposes (CS) is briefly described. A detailed discussion is then presented on experimental results obtained using: newly developed K-band SCPC earth stations; K-band small earth stations; C-band small capacity omniuse earth terminals; C-band receive-only small earth stations, along with the characteristics of on-board communications equipment; and K-band radio-wave propagation experiments performed during the second year of the mission.
