US-based Griffon (GFF) subsidiary Telephonics has secured production orders from the US Federal Aviation Administration (FAA) for 34 common terminal digitiser (CTD) systems.

The latest production order contract, in addition to the development programme, has a total value of $22.7m.

The CTD technology has been developed by Telephonics to process and convert radar signals from the legacy airport surveillance radar (ASR-8) and Beacon air traffic control systems (ATC) radar systems to the modern digital data standards required by standard terminal automation replacement systems (STARS).

Telephonics Communications and Surveillance Systems vice-president and general manager Mike Beltrani said: “We are extremely pleased to transition successfully into the production and delivery phase of our partnership with the FAA.

"We are extremely pleased to transition successfully into the production and delivery phase of our partnership with the FAA."

“This recent development places Telephonics firmly on the FAA's roadmap for air traffic management (ATM) modernisation, which we anticipate will provide additional opportunities to deploy civilian and military radar upgrades throughout the US and global ATC centres.”

CTD helps boost the FAA Next Gen initiative so that ASR-8, air traffic control beacon interrogator (ATCBI-5) and mode S radar systems can interface to the upgraded STARS ATCs deployed in TRACON facilities and control towers across the country.

In 2014, Telephonics secured the CTD programme award from the US federal agency as a multi-year contract that covers four future ordering periods, as well as supports FAA’s terminal automation modernisation replacement (TAMR) programme.

The solution will provide radar information or digitised real-time aircraft positions, identification and weather analysis to the TAMR system for US air traffic controllers.

This will allow air traffic controllers to monitor the airspace more effectively as well as increase air traffic safety.
