Covers 250,000 Square Nautical Miles Of Airspace
Sensis Automatic Dependent Surveillance – Broadcast
(ADS-B) ground-based transceivers are now being used to track air
traffic over Hudson Bay, Canada. The deployment provides Nav Canada
air traffic controllers with surveillance coverage of flights over
250,000 square nautical miles of airspace at 29,000 feet and above.
ADS-B enables more efficient flight paths that will greatly reduce
fuel consumption and emissions.
"Using ADS-B in a high traffic area such as Hudson Bay enables
us to significantly improve services to our customers in terms of
safety and overall operational efficiency," said Rudy Kellar, vice
president, operations at Nav Canada. "With the accuracy of Sensis
ADS-B, we can maximize airspace capacity by reducing separation
standards from the current procedural separation of 80 miles to the
five mile separation standard now used in airspace with
surveillance coverage."
ADS-B promises more efficient use of Hudson Bay airspace for
some 35,000 flights a year. With the reduced separation standard
allotted with ADS-B, properly equipped aircraft are able to climb
to optimal altitudes much earlier and to follow more efficient
routes. Once all aircraft using the Hudson Bay airspace are
equipped with ADS-B, Nav Canada estimates savings of approximately
18 million liters of fuel per year and reduced CO2 equivalent
emissions of 50,000 tons per year.
Sensis pioneered the development and implementation of ADS-B,
fielding the first operational ADS-B transceivers for both the Mode
S Extended Squitter (1090 ES) and UAT datalinks. All Sensis ADS-B
transceivers are also capable of transponder multilateration,
enabling independent verification of ADS-B data and serving as an
auxiliary system, making the deployment of Sensis multilateration a
cost-effective migration path to ADS-B while providing the benefits
of enhanced surveillance today.
"Sensis ADS-B is now the sole surveillance source for the
growing intercontinental traffic using this airspace," said Tony Lo
Brutto, vice president and general manager of Sensis Air Traffic
Systems. "This deployment demonstrates that Sensis transceivers
provide the precise, reliable surveillance demanded by one of the
most forward-looking ANSPs, delivering significant safety,
efficiency and environmental benefits to their customers."
Sensis continues to supply multilateration and ADS-B solutions
across Canada. Today, Sensis has deployed Multistatic Dependent
Surveillance for wide area terminal surveillance in Vancouver
Harbor and Fort St. John and for surface surveillance at Montreal
Pierre Elliott Trudeau International Airport.
In addition to Hudson Bay, Sensis is supporting Nav
Canada’s national ADS-B program with equipment provided for
the installations along the Labrador and Baffin Island coasts of
Eastern Canada.
