Performance Technologies Building Components for Ground-Based Regional Augmentation System (GRAS) for Airservices Australia

Project Includes Work with Honeywell Aerospace

ROCHESTER, N.Y., March 3 -- Performance Technologies (NASDAQ:PTIX), a leading developer of communication platforms and systems, today announced that it is working with Honeywell Precision Landing Systems in support of the Ground-based Regional Augmentation System (GRAS). This system is currently being developed by Honeywell for Airservices Australia to improve GPS-based navigation for commercial flights over continental Australia.

The GRAS system utilizes a network of VHF radio stations to transmit radio signals that correct for inherent GPS navigation errors. Performance Technologies' Advanced Managed Platform(TM) is utilized in building the ground-based navigation aid to compare the GPS information with the station's surveyed location, and identify errors in GPS, then links that information to the VHF transmitters for broadcast to airplanes.

Airservices Australia is a government-owned corporation providing air traffic control management and related airside services to the aviation industry. The Australian Flight Information region covers 11 percent of the earth's surface, including international airspace over the Pacific and Indian Oceans in addition to Australian airspace.

The Advanced Managed Platform (model AMP5095) is an integrated, high availability communications solution comprised of the following hardware and software from Performance Technologies:

o High-density, 7U chassis with redundant power and cooling

o 24-port, Gb Ethernet switch (CPC6600)

o 24-port T1/E1/J1 edge processor (CPC324)

o High-performance, IP storage blade (CPC5900)

o The company's exclusive Intelligent Shelf Manager architecture for remote monitoring

o NexusWare®, a CGL registered Linux® operating system and development environment

The GRAS deployment improves navigation accuracy, integrity, and overall safety for aircraft in flight. For airport terminals, the improved accuracy and integrity enables the GPS to provide lateral and vertical guidance, enabling pilots to safely fly an instrument approach to within 250 feet above the ground in low visibility or terrain challenged environments. Major benefits of the system include improved air safety and the ability for small airports without traditional navigation tools to operate in reduced visibility conditions.
