Operational broadcasting satellite program in Japan
Abstract
The Broadcasting Satellite-2 (BS-2) program using K-band frequencies is reviewed with emphasis on mission objectives, spacecraft, ground system, and home receiver. Objectives include solving TV reception difficulties in mountainous and remote areas of Japan, developing advanced service, and acquiring the technology of the broadcasting satellite. The spacecraft is three-axis stabilized and consists of a communication subsystem, tracking telemetry and command subsystem, and apogee kick motor, with a solar array total length of 890 cm at a weight of 350 kg after launch. The space segment of the BS-2 system consists of the BS-2a and BS-2b, which are positioned at 100 deg E, and are under development by the National Space Development Agency of Japan, which plans to launch them in 1984 and 1985, respectively. The construction and objectives of future facilities are also discussed.
