Airservices Australia is expanding its Automatic Dependent Surveillance Broadcast (ADS-B) activities in order to promote and exploit the safety and operational benefits made possible by the new data link technology.

Four correlated ADS-B programs are currently in various stages of development. A brief synopsis of each program is outlined below. For more information, click on the associated links.

Australian Transition to Satellite Technology (ATLAS)

Recent advances in the use of Global Navigation Satellite Systems (GNSS) for ‘only means’ navigation and the use of Automatic Dependent Surveillance Broadcast (ADS-B) for ‘radar-like’ services has made these two technologies viable options to advance Australia’s navigation and surveillance infrastructure into the 21st century. Australian Government aviation agencies are seeking comment on the proposed wider application of ADS-B and GNSS technologies to replace some of the existing radar and navaid network.

A Joint Consultation Paper has been prepared by Airservices Australia, the Australian Defence Force, the Civil Aviation Safety Authority and the Department of Transport and Regional Services. The paper sets out the proposal, including discussion of proposed funding arrangements and regulatory changes. The paper and supporting material is available from http://www.dotars.gov.au/aviation/airspace_reform/satellite_tech.aspx.

Status: Joint Consultation Paper published. Response period closed 31 October 2007 and responses are being reviewed.

Upper Airspace Program

A program aimed at providing near-term safety and operational benefits in high level, non-radar airspace. Includes installation of approximately 28 ADS-B ground stations, strategically located across Australia to provide air traffic surveillance above 30,000 feet in continental airspace outside of radar coverage.

Status: In progress - 11 of 28 ground stations commissioned and in use

Research and Development Programs

R & D activities to facilitate the Lower Airspace ADS-B Programs. Activities include development of low-cost ADS-B transmitters for general aviation aircraft, air to air ADS-B receivers and cockpit displays to provide airborne traffic information to pilots.

Status: In progress

International Activities

Airservices Australia on behalf of Australia is participating in a number of international forums and panels developing standards and procedures for the implementation of ADS-B technology for air traffic control. Airservices Australia also provides consultancy services in support of ADS-B programs in other States.

Status: In progress
