Shin Satellite Plc. of Thailand has awarded a contract to Space
Systems/Loral (SS/L) for the design and construction of iPSTAR-1, a high-powered geostationary satellite to be used for broadband communications applications. The contract includes training and support services, as well as an option for a second satellite.
Shin Sat will use iPSTAR-1, a spacecraft with a hybrid Ka-/Ku-band communications payload, to provide direct-to-desktop, last-mile services, including new multi-media and data services to customers in Asia, India, and Australia. The iPSTAR-1 satellite is scheduled to begin service in early 2003.
Shin Sat is a wholly owned subsidiary of Shin Corporations Plc., Thailand’s largest telecommunications company. Shin Sat currently operates three satellites, Thaicom 1A, Thaicom 2, and Thaicom 3, which provide a range of telecommunications services to customers in Asia, Australia, Africa, the Middle East, and most of Europe, managed through the company’s control center near Bangkok.
"In the past, SS/L has been a key contractor for a variety of Asian satellite projects, and we are very pleased to be continuing our work in this fast-growing part of the world," said Dr. John M. Klineberg, president of Space Systems/Loral.
The Satellite
With total satellite power of approximately 14 kW, iPSTAR-1 will provide 100 beams in the Ku-band and the Ka-band — to deliver broad coverage from its orbital location at 1200 East longitude. iPSTAR-1 is designed to provide 12 years of uninterrupted service life.
iPSTAR-1 will be a 1300S, a variation of SS/L’s successful 1300 satellite product line that supports power requirements between 6 and 18 kW. The 1300S satellite bus uses advanced technologies to enable satellite operators to support their customers with a wider range of services, and to deliver them with greater reliability.
The 1300S features larger and more efficient power-generating solar arrays with improved subsystems for managing and storing power; a more efficient means of heat dissipation; proven, fuel-efficient ion propulsion thrusters for station-keeping; and advanced command and control systems, all combining to provide a long useful life on orbit, as well as the exceptional reliability for which SS/L satellites are known. In addition, the bus has an expanded component mounting area.
Overall, SS/L satellites have accumulated nearly 800 years of reliable on-orbit service.
