Canadian Air Navigation Service Provider (ANSP), Nav Canada, will deploy wide area multilateration (WAM) technology from Saab Sensis to enhance flight safety around Springbank Airport.

Saab Sensis' Wide Area Multilateration (WAM) technology will provide air traffic controllers with expanded surveillance coverage.

Installation of the WAM system will mean that air traffic controllers have additional coverage from 100ft to 1,000ft above ground level (AGL) around Springbank Airport, providing surveillance data to a Nav Canada radar data processor.

Nav Canada engineering vice president Kim Troutman said that the system will deliver accurate and customisable surveillance in locations where radar has limitations due to terrain and other obstacles.

"For Springbank, WAM is a cost-effective method of providing Controllers with additional surveillance coverage, which will improve safety and efficiency for aircraft using this airport," Troutman said.

Saab Sensis' Multilateration provides air traffic controllers with precise aircraft position and identification information in any weather condition by using multiple low-maintenance, non-rotating sensors.

"The system uses a minimal number of sensors to reduce complexity and minimise lifecycle cost solution, the company said."

Saab Sensis claimed that the system has a higher update rate and greater positional accuracy than traditional radar and offers enhanced safety, capacity to improve efficiency of airspace and surface operations.

The system uses a minimal number of sensors to reduce complexity and minimise lifecycle cost solution, the company said.

Each of the multilateration sensors supports Automatic Dependent Surveillance - Broadcast (ADS-B).

Saab Sensis senior vice president and general manager Ken Kaminski said that Springbank will become the fourth location in Canada to deploy the company's WAM system to enhance flight safety.

"WAM's extensible nature means that the Springbank system can easily be expanded from the terminal area surveillance into a wide area network for en route coverage," Kaminski said.
