SPARKS, Nev. -- Sierra Nevada Corporation’s (SNC) new Surface Mount Technology (SMT) solar array is operational and already providing 25 percent more power to its host spacecraft than a conventional solar array designed for the same application, the company announced.
SNC said the revolutionary technology is being used on the Air Force Research Laboratory’s (AFRL) Satellite for the High Accuracy Radar Calibration (SHARC) mission, launched from the International Space Station via NanoRacks LLC earlier this year.
Among other goals, SNC said SHARC is demonstrating calibration capabilities needed to track orbital objects such as satellites and debris. The SMT arrays have been successfully providing power on SHARC for the last few months.
“Platforms like the SHARC satellite help validate not only our missions, but other new technologies such as SNC’s SMT solar arrays,” said Kyle D. Kemble, Air Force Research Laboratory mission manager.
“This mission is the perfect example of how small satellites, co-developed between government, academia and industry, can prove state-of-the-art technologies and determine the future of next-generation satellites.”
The SHARC solar panel is an efficient and agile product, SNC said, and was rapidly delivered to AFRL after the contract was awarded. The streamlined design, test and manufacturing process allowed the hardware to be completed in just three months.
Future missions will continue to demonstrate this short time cycle for design and manufacturing phases – critical to the rapidly emerging small satellite constellation market.
“SNC is pleased to introduce our SMT solar arrays into the market to meet an ever-increasing demand in low-cost, low lead-time subsystems,” said John Roth, VP of business development for SNC’s Space Systems business area located in Louisville, Colorado.
“Future missions will benefit from our SMT technology in two possible ways. Spacecraft with the same-sized solar array as a traditional system will have more power for payloads, or the panel size could be reduced – giving that weight and volume to other critical systems. This provides our customers with design flexibility at a much lower cost.”
