Digital transmission experiments with the CS satellite
Abstract
The Japanese Medium-capacity Communications Satellite for Experimental Purpose (CS) was launched on December 15, 1977 and put into the geostationary orbit on 24. There are six K-band (30/20 GHz) transponders and two C-band (6/4GHz) transponders on the CS equipment platform. An experimental plan is prepared by the Radio Research Laboratories (RRL), Ministry of Posts and Telecommunications of Japan and involves many kinds of digital communications experiments. They are PSK fundamental transmission tests, PCM-PSK (telephone) communication experiments, HO-DPCM-PSK (television) communication experiments, PCM-PSK-TDMA communication experiments involving site diversity switching techniques, Delta-M-PSK-SCPC experiments and digital SSRA experiments.
