The Japanese Communications Satellite 5 (JCSat 5) was launched to relay voice, data and television signals to Japan, with multiple beams for international coverage west to India, south to Australia and New Zealand, and east to Hawaii. JCSat-5 carried four octagonal communications antennas and two wings with four solar panels each. The payload consisted of 12 active C-band transponders and 28 active Ku-band transponders with an expected lifetime of at least 12 years. It was placed in a geosynchronous orbit at 139.4 deg E initially, but was planned to be operated over 150 deg E.
