Alexandria, VA – July 6, 2006 – Rannoch Corporation announced today that Don Antonucci has been appointed as an independent Director to the company’s Board of Directors. Don brings 35 years of experience in serving both the military and civil markets, worldwide. His focus over the last decade was aviation and air traffic management.

Previously, Don was President of Lockheed Martin’s Transportation and Security Solutions,specializing in advanced aviation management, security and other mission-critical information technology solutions. His areas of focus included air traffic management; airport, physical and border security; and civil agency efforts involving advanced systems for managing sensitive information, such as census data capture, electronic records archiving, and communications network infrastructure programs.

“We are pleased to welcome Don to our Board of Directors,” stated Alex Smith, Rannoch’s Chairman and Chief Executive Officer. ”Don’s extensive experience in the air traffic management and security industries is highly relevant to Rannoch as the company takes on new challenges in global air traffic management and surveillance. As the company manages aircraft tracking projects for air traffic control, airport operations, and military applications, in markets ranging from Miami to Mongolia, Don’s proven leadership and vision will be invaluable at the corporate level.”

Rannoch is a leading provider of aircraft identification and tracking technologies with broad application in air traffic control (ATC), commercial airport operations and management, and the military and homeland security markets. In the 1990’s the company helped pioneer a new way to track aircraft at a significantly improved performance, beyond the capabilities of mature radar systems for a fraction of the cost.

The utility of the new tracking technology has gained global momentum and many countries,ranging from Taiwan, to Germany, to Canada, have adopted the technology as a part of their next generation air traffic control systems.

“I am pleased to accept yet another challenge at this point in my career,” stated Don Antonucci.“Rannoch has an exciting technology and intellectual property portfolio which should position the company well for many important next generation air traffic management initiatives worldwide. I look forward to assisting the company’s leadership in meeting their goals over the next several years.”

Fueling the demand is the overall growth in air traffic, both passenger and cargo, which today is constrained by legacy routes and the accuracy limitations of the current surveillance radar infrastructure. The new technology will allow creation of new routes, expansion of existing routes, and because the technology can track aircraft precisely, it will allow decreased separation of aircraft in the air space without sacrificing safety. This in turn supports new airport development and dramatic expansion of existing airports to accommodate the growing demand for air traffic.

The new technology, known as extended Automatic Dependent Surveillance, or ADS-X,includes an advanced form of triangulation using time difference of arrival (TDOA) processing of an aircraft’s transponder signal at multiple dispersed receiver locations. The triangulation functionality, in cooperation with ADS-B allows Rannoch systems to track all classes of aircraft regardless of old or new transponder equipage, and facilitates an orderly, safe transition to the next generation air traffic surveillance environment. Rannoch currently markets a comprehensive suite of multilateration solutions under the AirScene brand.

Don Antonucci added, "I was very impressed by the dedication and focus of the Rannoch team as they invest in technology solutions that address the tactical needs of their customers while demonstrating a strategic understanding of dynamic operational needs for tomorrow's airspace."
