Australia's recently launched automatic dependent surveillance-broadcast (ADS-B) trial is attracting interest from the Indian subcontinent and South-East Asia, says Airservices Australia. ADS-B flight trials were launched last month in the Burnett Basin region in Queensland (Flight International, 11-17 February). The service provider says 20 ADS-B ground stations could cover the country and, at A$300,000 ($177,000) per ground station, would be cheaper than conventional systems.
