SRA Subsidiary ERA Completes Site Acceptance at Cape Town

Eras system provides wide area surveillance in the Cape Town terminal area out to 60 nautical miles from the Cape Town International Airport. Data from the system will be fed to the ATNS EUROCAT system and fused with primary and secondary surveillance radar information to provide air traffic controllers complete situational awareness. The system will be used operationally once certification from the South African CAA has been obtained. ATNS is proud of its pioneering work with multilateration and ADS-B, and we can see the benefits these technologies will bring to our surveillance needs today and for our surveillance infrastructure of tomorrow, said Chris Steyn, the Cape Town Wide Area Multilateration Project Manager. Era has consistently proven that they are able to deliver sophisticated next generation surveillance systems that meet our stringent quality standards. Eras ADS-B and multilateration system provides higher accuracy, greater update rates, better coverage and improved reliability when compared to traditional radar, at a much lower initial cost and with lower annual maintenance costs. ATNS is an industry-respected ANSP with extremely rigorous standards and we are honored that they have continually relied on Era to deliver next-generation surveillance solutions, said SRA Senior Vice President of Air Traffic Systems, Kevin Layton. Era is also currently in the process of completing two next generation surface surveillance systems for ATNS. The systems one at Cape Town International and one at O.R. Tambo International Airport in Johannesburg are being installed to support the growing passenger demand and increased operations, especially as they prepare for the 2010 World Cup.

SRA International, Inc. (NYSE: SRX), a leading provider of technology and strategic consulting services and solutions to government organizations, announced that Era Systems Corporation, a subsidiary of SRA, was awarded a contract by ANS CR, the Czech Air Navigation Service Provider, to deploy a wide area multilateration system in Brno, Czech Republic. Eras solution, also capable of decoding ADS-B signals, will provide surveillance coverage out to 80 nautical miles from the Brno airport. Eras system in Brno will be the third wide area multilateration system installed by ANS CR, following systems deployed in Ostrava and Prague, and will be the final system needed to provide complete nationwide coverage. It is our full intention to interconnect all three wide area multilateration systems early in 2010 to create the worlds first nationwide wide area multilateration capability, said Ivan Uhlir, ANS CR surveillance expert. We are excited to once again be partnering with Era in this endeavor as they have proven time and again their industry-leading multilateration capabilities. Multilateration is unique in that it can decode both traditional transponder signals as well as ADS-B transmissions, and when compared to conventional secondary radar, provides much higher position accuracy, faster update rates, better coverage and improved reliability. The ANS CR have always been innovators, installing the worlds first surface multilateration system and the worlds first wide area multilateration system, said Russell Hulstrom, Vice President of Eras Air Traffic Management business. Creating the worlds first nationwide wide area multilateration solution is another important step towards the transition to a world beyond radar. Era is the world leader in wide area multilateration and has been chosen by ten ANSPs around the globe to provide various wide area multilateration applications, more than any other wide area multilateration provider. Acquired by SRA in July 2008, Era Systems Corporation provides advanced surveillance technologies for the air traffic management, airport operations, military and security markets.
