Alexandria, VA – December 12, 2006 – Rannoch Corporation announced today the acquisition of BAE’s TAMIS solution, the leading Airport Noise and Operations Monitoring System (NOMS) in the U.S. today. The TAMIS solution is deployed at some of the world’s largest airports including Atlanta, Dallas, Phoenix, Baltimore, and New York.

The TAMIS product group brings a long track record of success in the NOMS business, having installed their first fully integrated system in 1974. The TAMIS group also revolutionized the industry when they produced the first secure web-based NOMS software, eTAMIS, early in 2002. The group possesses the most experienced workforce in the industry, with many members exceeding 20 years in the NOMS field. That dedication to industry excellence remains a core value today.

“The eTAMIS software is widely regarded as the best supported product in the industry”, said Dave Ellison, President and CEO of Rannoch. “With our ADS-X technology providing real-time accurate flight tracking data, we are now able to offer our customers a solution that delivers the most accurate flight tracking data with the most powerful analytical tools for flight and noise analysis”.

The industry’s first web-based solution, eTAMIS, is the only proven web-based NOMS software installed in the U.S. and has a fast-growing client list. Used throughout the airport noise community, the eTAMIS solution includes a powerful reporting engine and graphical tools which correlate various flight, noise, weather, and complaint metrics.

The eTAMIS product now forms the basis of Rannoch’s AirScene NOMS product offering, which combines the eTAMIS analytical tools with Rannoch’s proven multilateration flight tracking and noise monitors from its strategic partner B&K, the world leader in noise monitoring equipment.

With its acquisition of ERA a.s. in October, Rannoch became the global leader in ADS-X (eXtended ADS) multilateration and ADS-B flight tracking technologies for air traffic control, military and airport operations. With the acquisition of the TAMIS group, Rannoch’s AirScene is now able to provide the most powerful NOMS tools in the industry with the most accurate realtime flight tracking data provided by the same infrastructure of sensors.
