Concurrent to Supply Real-Time Linux Solution to the U.S. Navy

Concurrent, a provider of time-critical Linux operating systems and integrated software and computer solutions for mission-critical applications, today announced that Crane Division, Naval Surface Warfare Center (NSWC Crane) has selected Concurrent's fully-integrated iHawkTM multiprocessor systems running RedHawkTM real-time Linux for a hardware-in-the-loop (HITL) simulation application.

Currently in development, this missile simulator system will provide input signals to actual missile guidance hardware in real-time and read the missile's response to provide a closed loop simulation. NSWC Crane is developing the simulator in partnership with multiple DoD labs.

The simulator will be used to determine the effectiveness of Navy and Marine Corps aircraft countermeasure systems that protect the aircraft from hostile missiles. The simulator's multiple roles include optimizing new countermeasures in existing aircraft, determining the best use of existing countermeasures in new aircraft, and evaluating current aircraft capabilities against new missile system threats.

Concurrent's RedHawk Linux allows users to assign real-time simulation tasks to dedicated processor cores thereby guaranteeing the needed real-time response and determinism. Memory and data are shared between processors with minimal overhead during real-time operation. The solution also provides seamless integration and execution of The MathWorks' MATLAB/Simulink models in real-time without the need for time-consuming programming and system set up. The fully integrated solution provides all the necessary tools needed for automatic code generation, intelligent instrumentation and real-time model execution.

"We needed a COTS (commercial off-the-shelf)-based platform solution that could perform real-time analog and digital I/O while easily executing Simulink models," said Mr. John Bennett, Scientist, NSWC Crane. "We evaluated other alternatives, and selected the Concurrent COTS based iHawk system with RedHawk real-time Linux based upon our contract requirements."

"The missile simulator for use by NSWC Crane based on a Concurrent iHawk is another example of the U.S. Navy's selection of RedHawk Linux for its real-time needs," said Gary Beerman, Marketing Director, Concurrent. "Already deployed in the Aegis Weapons Systems program, RedHawk is rapidly becoming a de facto real-time Linux operating system for Navy programs. We are pleased and honored to continue our technology and service provider relationship with the military."
