Calgary International To Augment Surface Radar With
Multilateration
NAV CANADA, the Air Navigation Service Provider for Canada, is
deploying Saab Sensis Corporation’s multilateration system
for surface surveillance, including VeeLo NextGen vehicle locators,
at Calgary International Airport for improved all-weather surface
situational awareness.
Calgary International currently uses radar for surface
surveillance. As part of this project multilateration system data
will be fused with radar data for seamless, continually updated
surveillance. The location and identity of vehicles will appear on
controllers' surface displays.
Saab Sensis multilateration uses multiple, low-maintenance,
non-rotating sensors to triangulate aircraft based on transponder
signals. It has a higher update rate and greater positional
accuracy than traditional radar, uses advanced processing
techniques to minimize the required number of sensors, and is ADS-B
compatible.
VeeLo NextGen is a small, lightweight device in a rugged,
weather-resistant enclosure that is attached to the exterior of an
airport vehicle to provide controllers with situational awareness
of vehicles operating on the airport surface. The vehicle locator
attains its position from GPS and broadcasts location and identity
using the Mode S Extended Squitter ADS-B message format. VeeLo
NextGen automatically turns off when the vehicle travels outside of
the movement area, ensuring an efficient use of available aviation
spectrum.
Saab Sensis serves military, civil aviation, airport and airline
customers in more than 35 countries across six continents.
NAV CANADA is the country's civil air navigation services
provider, and is a private sector corporation.
