Nav Canada, the air navigation aervice provider (ANSP) for Canada, is deploying Saab Sensis’ Wide Area Multilateration (WAM) technology at Springbank, Alberta. The WAM system will enhance the safety of flight around Springbank Airport by providing Nav Canada air traffic controllers with additional surveillance coverage not available with the existing radar, the company said.

The WAM system will provide additional coverage from 100 feet to 1,000 feet Above Ground Level (AGL) around the airport, providing surveillance data to a the ANSP’s radar data processor.

Multilateration uses multiple non-rotating sensors to triangulate aircraft location based on transponder signals, providing air traffic controllers with precise aircraft position and identification information regardless of weather conditions. Each multilateration sensor supports Automatic Dependent Surveillance – Broadcast (ADS-B), the company said.

“Springbank will become the fourth location in Canada to enhance flight safety by utilizing Saab Sensis WAM to address challenging surveillance coverage demands not easily achieved with traditional radar,” said Ken Kaminski, senior vice president and general manager of Saab Sensis. “WAM’s extensible nature means that the Springbank system can easily be expanded from terminal area surveillance into a wide area network for en route coverage.”
