Wide area multilateration from Sensis used to control Tasmania Airspace

EAST SYRACUSE, N.Y., 2 Nov. 2010. Sensis Corp.'s wide area multilateration (WAM) system over Tasmania, Australia has passed its safety case by the Civil Aviation Safety Authority (CASA) and is now operational. The system uses both multilateration and Automatic Dependent Surveillance -- Broadcast (ADS-B) to provide Airservices Australia with enhanced en route surveillance of air traffic across the island and down to the surface at Hobart and Launceston Airports. Sensis WAM's precise surveillance of aircraft enables air traffic controllers to implement five nautical miles of aircraft separation for safer, more efficient use of the airspace in a region that was previously controlled with procedural separation standards.
