Palapa-D satellite program began in February 1975 by ordering two satellites at once (Palapa A1, A2) and its control station and 9 earth stations in Hughes (Boeing Satellite Systems). The process is also only takes 17 months just to build and launch the first satellite Palapa A series which is the fastest execution ever carried out by management and Boeing engineers.
Palapa-A antenna designed for transmitting power is concentrated into the Indonesian archipelago and also includes neighboring countries namely, Singapore, Malaysia, Thailand and the Philippines. Availability of 12 transponders with an average capacity of 6000 voice channels or 12 channels of simultaneous television over the archipelago, six of which are used for telephony and one transponder filled the national television program, while the remaining were for backup.
Palapa-A1 successfully launched and operated on July 8, 1976 in orbit 83E are fully managed by national companies PERUMTEL (PT Telkom). Intermittent one year later ie on 11 March 1977, Palapa-A2, located at 77E orbit, launched from Kennedy Space Center in Cape Canaveral, Florida, United States, as a reserve which also has 12 transponders and is ready to operate when the Palapa-A1 experience failure, or if market demand can no longer be accommodated by the Palapa-A1. Both satellite Palapa-A was successfully launched by Delta-2914 launch vehicle and has a relatively short life. Finally, years of service both prime Indonesian communications satellite ended in June 1985 and January 1988, and continued on a second-generation satellite program that is the Palapa-B.
