NAV CANADA Selects Sensis Multilateration for Montreal Pierre Elliott Trudeau International Airport

NAV CANADA Partnering with Aéroports de Montreal to Implement Multilateration to Increase Capacity and Efficiency at Trudeau

EAST SYRACUSE, NY – November 3, 2008 – NAV CANADA is deploying Sensis Multistatic Dependent Surveillance (MDS) multilateration for surface surveillance at Montreal Pierre Elliott Trudeau International Airport.  In addition, Sensis VeeLo NextGen™ vehicle locators will be used for tracking airport vehicles in the maneuvering area.

“With its advanced surveillance capabilities, MDS promises to help reduce costly delays, contributing to lower airline fuel costs and reduced greenhouse gas emissions,” said John Crichton, NAV CANADA President and CEO. “MDS will complement the surface radar technology we currently have in place.  Radar sometimes has limitations due to obstacles, line of sight and poor weather conditions.  By identifying the aircraft and vehicles through transponder-based multilateration, MDS will help provide NAV CANADA controllers and airport personnel with a more complete picture of the airport surface.”

Sensis MDS uses multiple low-maintenance, non-rotating sensors to triangulate aircraft location based on transponder signals and supply 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 MDS provides consistent, accurate surveillance performance.  MDS’ architecture and advanced multi-path elimination algorithms result in precise surveillance using the optimal number of ground stations for reduced cost and complexity.  Additionally, each MDS sensor supports Automatic Dependent Surveillance – Broadcast (ADS-B) – a technology that is being deployed by NAV CANADA today to provide accurate coverage for en-route surveillance.

Sensis VeeLo NextGen is a Mode S-based vehicle locator that features a WAAS-enabled GPS receiver and broadcasts its position and identity using the Mode S Extended Squitter ADS-B message format.  This enables accurate and reliable detection, tracking and identification of airport surface vehicles.

“Aéroports de Montreal and NAV CANADA have worked closely to ensure that NAV CANADA controllers and ADM airport personnel at Montreal have the most advanced, widely deployed surface surveillance technology available, Sensis MDS,” said Tony Lo Brutto, Vice President and General Manager of Sensis Air Traffic Systems. “With the VeeLo NextGen units providing accurate vehicle location and identification information, the integrated solution provides controllers with extensive situational awareness for safety, capacity and efficiency improvements at one of Canada’s busiest airports.”

Sensis continues to be the supplier of choice for multilateration and ADS-B solutions across Canada.  Today, Sensis has deployed MDS for wide area terminal surveillance in Vancouver Harbor and Fort St. John, and is leading the roll-out of NAV CANADA’s national ADS-B program with installations in Hudson Bay and along the Labrador and Baffin Island coasts of Eastern Canada.

Sensis multilateration is the most field-proven system in the industry, with more than 90 sites worldwide.  More than 50 airports worldwide rely on Sensis technology as a critical component of a complete Advanced – Surface Movement Guidance and Control (A-SMGCS) solution.
