The 100,000-square-foot TRW Space Power Production Facility (SPPF) at the company's Space Park campus contains state-of-the-art, custom-designed automated equipment for interconnecting, testing and inspecting solar cells, and spacious areas for assembling solar panels, solar arrays, electrical cables, harnesses and batteries.

"SPPF enhances TRW's competitive position as a high-volume producer of solar arrays and components for commercial markets and for our own space systems," said Allan M. Frew, vice president and general manager, Space & Technology Division. "We see demand increasing in the coming years, and we intend to be the premier supplier to the marketplace."

The SPPF is an example of TRW's on-going investment in the people, plants and processes necessary to develop highly competitive products and space systems. The facility utilizes software developed by TRW to control solar array manufacturing and inspection equipment, and to operate a real-time inventory control and data collection management system.

This capability permits TRW to accommodate crystalline silicon and gallium arsenide solar cells of any size, without changing equipment or tooling. It also:

• Significantly reduced labor costs;
• Cut solar cell attrition rates;
• Increased annual capacity by a factor of three, to the equivalent of 25 typical geosynchronous satellites; and,
• Reduced product change-over time from seven days to half a day.

TRW is also introducing an additional production line for processing amorphous silicon chips in the coming months.

In addition to manufacturing solar arrays and other spacecraft components, TRW offers a complete range of solar array design services, such as concept development, photovoltaic engineering, product design, structural and mechanical design, radiation effects analysis, materials engineering and other disciplines.

TRW's solar arrays have provided more than 600 years of power to more than 190 military and commercial spacecraft over the past four decades, with no on-orbit failures.

Satellite Launch To Boost DTH In India
Calcutta, India (SPX) Dec 28, 2005
The successful launch Thursday of India's heaviest satellite from spaceport of Kourou in French Guyana may have boosted the country's space research efforts to yet another level, but it has also lifted the spirits of at least three Direct-To-Home televisions broadcasters, one of which has been waiting for years to launch its services in India.
