ATLANTA, 19 May 2005. EMS Technologies, Inc. announced today that its Defense & Space Systems division has been awarded a contract valued at $1.3 million by the Defense Microelectronics Activity (DMEA) and Air Force Research Laboratory (AFRL) to advance next-generation Beam Forming Network (BFN) technology for satellite communication systems.

The goal of the effort is to reduce mass by a factor of three over the current state-of-the-art for these satellite subsystems, in which mass and volume are highly critical. EMS's enabling capability to miniaturize the packaging for advanced ferrite technology and mixed-signal drive electronics was a key factor in being selected. Work on the contract is expected to extend through early 2006.

BFN's are a key subsystem of advanced communication satellites that provide the capability to steer and shape the receive antenna patterns to provide anti-jam protection. The BFN's shaped antenna patterns automatically zero out, or "null," signals from potential jammers, while permitting friendly users within the area of coverage to communicate.

"We are pleased to have been selected by DMEA and AFRL to accomplish this advanced technology insertion and maturation effort. With continued technology maturation, extremely capable beam management for future satellite systems will be assured," said Jay Grove, senior vice president & general manager at Defense & Space Systems.

EMS Technologies, Inc. is a leading innovator in the design and manufacture of wireless, satellite and defense solutions, and focuses its unique range of advanced technologies on the needs of broadband and mobile information users. The company is headquartered in
Atlanta, has almost 1,800 workers worldwide, and operates manufacturing facilities in Atlanta, Montreal, Ottawa and Brazil.
