Tracking aircraft via digital TV broadcasts

13 February 2013

Thales and partners to research air traffic management of the future Aircraft entering UK airspace could soon be located and tracked by monitoring their interaction with digital TV broadcasts.

The Technology Strategy Board, the UK's innovation agency, today announced funding for a two-year study by Thales UK, NATS and Roke Manor Research into how an innovative system that utilises existing digital TV signals could support the UK's future air traffic management.

this innovative application of new technology could reshape the way that air traffic is managed

The system works by having a number of ground stations that receive the same TV signal; each receives the signal at a slightly different time because of the reflections and interactions with aircraft flying in their vicinity. The received signals are then compared to the original broadcast, and the difference is used to triangulate the position of the aircraft.

This new and pioneering type of radar known as multi-static primary surveillance radar is only now possible because of the increased power and reduced cost of processor technology. Through the development of a prototype system, the study will investigate the wide range of benefits it could offer to air traffic management (ATM).

The large number of TV transmitters already located across the UK could provide a more reliable infrastructure than the current system, which typically relies on one radar per airport. The continued availability of transmissions is safeguarded because the digital TV network is part of the UK's critical national infrastructure, although the study will also examine how service level agreements with broadcasters could further ensure reliability and performance.

Using existing digital TV broadcasts would mean that dedicated transmitters are no longer needed, which could simplify the system, lower the power consumption, and reduce the financial commitment of maintaining the ATM infrastructure.

Importantly, it would also mean that the existing radio spectrum used for air traffic management could be re-used to meet the increasing demand for wireless communications and other requirements. Another key benefit is the reduced interference from wind turbines, thus ensuring a safer flying environment.

The funding that we have secured today from the Technology Strategy Board is a significant endorsement of the potential long-term benefits of this research, said Marion Broughton, head of Thales UK's aerospace business. Although in its infancy, this innovative application of new technology could reshape the way that air traffic is managed in the future. This is a good example of how Government and industry can work together, share expertise, and sustain innovation and high-technology research within the UK.

Notes to Editors

Thales is the global market leader in air traffic management, civil radars and navigation aids. There are more than 130 Thales air traffic management systems in service throughout the world, and Thales air traffic equipment is used by two-thirds of the aircraft that take off and land around the world every day.

Thales UK and NATS have formed a consortium with Babcock, Frequentis and Jotron acting as Key Sub-Contractors operating under the brand AQUILA Air Traffic Management Services. AQUILA ATMS have been selected by the UK MOD to compete for PROJECT MARSHALL to deliver Military ATMS over a period of 22 years.
