Spectrum Signal Processing Selected by Harris Corporation to Support the U.S. Navy Multi-Mission Unmanned Surface Vehicles

The second contract between Harris Corporation and Spectrum Signal Processing to support future U.S. littoral systems

COLUMBIA, MARYLAND--(CCNMatthews - March 1, 2007) - Spectrum Signal Processing (USA) Inc., a subsidiary of Spectrum Signal Processing Inc. (TSX:SSY)(NASDAQ:SSPI), today announced that the Government Communications Systems Division of Harris Corporation (NYSE:HRS) has selected Spectrum's flexComm™ SDR-4000 rugged software defined radio (SDR) solution to be deployed in field trials of the United States Navy's Multi-Mission Unmanned Surface Vehicles (MMUSV). Under the agreement, Spectrum will supply the signal processing system onboard the MMUSV that communicates with a processing system aboard a Littoral Combat Ship. Field trials for the MMUSV are scheduled to begin in early 2007.

The MMUSV, a vessel similar to a rigid inflatable boat, is one of the mission modules that can launch from a Littoral Combat Ship. It is designed to operate autonomously and thereby protect boat operators from threats and attacks including extreme environmental conditions and hazardous electromagnetic attack. The MMUSV can be configured to support several different types of missions such as side scanning sonar data collection, weapons missions, anti-submarine warfare or surface ship warfare. Each of these missions will require a different type of data to be collected and communicated to the Littoral Combat Ship. Spectrum's SDR-4000 will be used to enable the transmission of these different data types.

"The software defined nature of the SDR-4000 provides flexibility in how different types of data can be transmitted. This flexibility, combined with the low power and small form factor design of the SDR-4000, makes it an ideal solution for this complex application," said Ken Schumacher, Senior Program Manager, Harris Corporation Government Communications Systems Division. "Spectrum's modular and reconfigurable architecture allows Harris to leverage the foundational knowledge and technology invested in previous developments and apply it to the MMUSV application, saving us valuable time." He adds, "Spectrum's responsiveness and solution based approach to business has made them a valuable supplier to Harris."

"The reconfigurable architecture of Spectrum's products enables customers like Harris to leverage their investments across multiple projects," said Michael P. Farley, President of Spectrum Signal Processing (USA) Inc. "This contract builds on our existing relationship with Harris and underscores Spectrum's value to leading defense contractors."

Spectrum's SDR-4000 is a 3U CompactPCI® subsystem that is comprised of two major component level hardware products: the PRO-4600 SDR modem processing engine and the XMC-3321 dual transceiver input/output mezzanine card. RapidIO™ provides a high bandwidth interconnect fabric between these cards, as well as the input/output functionality to ensure the efficient use of the processing resources. Software development tools include Spectrum's quicComm™ hardware abstraction layer, which facilitates algorithm partitioning and programming, and a real-time operating system. The SDR-4000 can be optimized for program specific size, weight, power consumption, cost and rugged requirements. For more information on the SDR-4000, please visit www.spectrumsignal.com/products.
