Mercury Computer Systems To Deliver Integrated ATCA®-based Signal Processing Subsystem To Support Satellite Telecommunications System

Mercury Computer Systems, Inc. (NASDAQ: MRCY, www.mc.com), a trusted provider of commercially developed application-ready ISR and EW subsystems for defense prime contractors, confirmed that it had been previously awarded a contract from a leading telecommunications provider to deliver an integrated signal processing subsystem based on the ATCA ® standard. The high performance subsystem, a ground-based gateway, will enable vital terrestrial-satellite communications for a next-generation mobile satellite system to be used for national security, civilian and humanitarian efforts.

“Mercury has forged a very close relationship with this company, working on a range of satellite-based telecommunications systems and similar programs over a long period of time. Our solutions are known for their maturity, reliability and performance, and our team has earned a reputation for our commitment to supporting the performance goals and ultimate success,” said Didier Thibaud, senior vice president and general manager of Mercury Computer Systems’ Advanced Computing Solutions business unit.

Mercury’s expertise in designing and integrating high performance signal processing subsystems based on the ATCA and RapidIO ® standards was a critical asset in winning this design. Mercury will deliver an ATCA-based platform that implements hundreds of digital signal processors (DSPs), interconnected by the RapidIO switch fabric, to deliver high bandwidth, low latency, deterministic performance. Using proven technology, Mercury’s subsystem provides massive processing power and manufacturing readiness, reduces costs and shortens development cycles. Because it is based on open standards, the solution can be easily upgraded over time.
