HERNDON, VA - January 22, 2007 - Objective Interface Systems, Inc. today announced that General Dynamics C4 Systems selected ORBexpress® communications middleware as the sole Object Request Broker (ORB) for the Joint Tactical Radio System (JTRS) Handheld, Manpack, Small Form Fit (HMS) Cluster. The JTRS HMS radios include fourteen small, light-weight "form factors" that will enable warfighters to be more agile and covert than current radios allow. Each JTRS HMS radio features an advanced core receiver the size of a credit card, which supports the primary radio functions for each form factor. The JTRS HMS radio product lines allow individual warfighters to have networked communications capability, enabling coordinated joint force and coalition operations.

As prime contractor, General Dynamics is integrating the hardware and software operating environment of the JTRS HMS radios. The JTRS HMS radios are based on the Software Communications Architecture (SCA), developed by the U.S. Department of Defense. A key component of the SCA is the use of Common Object Request Broker Architecture (CORBA). Objective Interface's ORBexpress RT is a real-time CORBA ORB that enables software developers to simplify the development of distributed software applications, build scalable, efficient and robust applications, and reduce overall development time.

"As a small-footprint product, ORBexpress optimizes the use of scarce resources, which is important for small, light-weight, low-power radios. As real-time communications middleware, ORBexpress provides the predictability of behavior and reliability required for SDR platforms," said Bill Beckwith, CEO/CTO of Objective Interface Systems. "We are proud to support General Dynamics' efforts in developing small, power-efficient radios that enable joint force operations to communicate more seamlessly with each other."
