Sensis Corp.'s Wide Area Multilateration (WAM) system over Tasmania, Australia, passed its safety case by the Civil Aviation Safety Authority (CASA) and is now operational, the company announced Monday.
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. The system allows 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, according to the company.
Sensis WAM uses multiple non-rotating sensors to triangulate aircraft location based on transponder signals and to provide air traffic controllers with precise aircraft position and identification information, regardless of weather conditions. With a higher update rate and greater positional accuracy than traditional radar, Sensis WAM provides effective surveillance for increased safety, capacity and efficiency of airspace and airports. With its advanced processing techniques, a Sensis multilateration system uses the minimal number of sensors for a less complex, lower lifecycle cost solution.
