OTTAWA, Jan. 22 /CNW Telbec/ - With the first flight over Hudson Bay
using new air-traffic-surveillance technology, an 850,000-square-kilometre gap
in Canada's radar coverage has been eliminated, NAV CANADA announced today.
The breakthrough technology is known as Automatic Dependent Surveillance
- Broadcast (ADS-B). It combines satellite links, onboard equipment, ground
stations, and communication links to provide air traffic controllers the same
kind of information provided by radar. (To view Backgrounder, <a href="http://www.navcanada.ca/NavCanada.asp?Language=en&Content=ContentDefinitionFiles\Newsroom\Backgrounders\ads_b.xml">click here</a>).
ADS-B promises more efficient use of Hudson Bay airspace for some 35,000
flights a year, with significant savings in fuel costs, flight times and
greenhouse-gas emissions. . (To view map, <a href="http://www.navcanada.ca/ContentDefinitionFiles/Newsroom/NewsReleases/2009/nr0122_img1_en.jpg">click here</a>).
On January 15, the first use of ADS-B involved Air New Zealand Flight 1
(ANZ 1) and air traffic controller Karim Mekki at the Montreal Area Control
The flight had departed from London, England enroute to Los Angeles,
California. Mekki tracked the aircraft on his display for about 25 minutes as
it flew over Hudson Bay. (To view photo of Karim Mekki, <a href="http://www.navcanada.ca/ContentDefinitionFiles/Newsroom/NewsReleases/2009/nr0122_img2_en.jpg">click here</a>).
"ADS-B is based on equipment on board the aircraft that tells us the
exact position of the plane" says Rudy Kellar, Vice President, Operations at
NAV CANADA. "It's the surveillance system of the future because it's more
accurate than radar and much more affordable. ADS-B makes it possible for us
to significantly improve service in remote locations like Hudson Bay."
The new surveillance system provides radar-like coverage for a fraction
of the purchase, installation and maintenance costs. Sensis Corporation is
supplying NAV CANADA with its ADS-B equipment consisting of an antenna, a
receiver and a target processor installed at ground stations along the Hudson
The stations are connected to telecommunications links that send data to
controllers at Area Control Centres. The technology is digital, solid state,
with no moving parts and a minimal support infrastructure. (To view photos,

To use ADS-B airspace, aircraft need to be equipped with the proper
avionics. Air operators require Transport Canada approval before NAV CANADA
can accept their down-linked ADS-B data.
For aircraft using ADS-B airspace, cost savings are based on maximizing
airspace capacity and efficiency through reduced separation standards that
allow aircraft to climb to optimal altitudes much earlier, and to follow more
efficient routes to destination.
NAV CANADA estimates customer savings of about 18 million litres of fuel
per year and reduced C02 equivalent emissions of 50,000 tonnes per year, once
all aircraft using this airspace are equipped for ADS-B.
More savings are expected in the next few years for North Atlantic
traffic as NAV CANADA expands its ADS-B coverage over the eastern coast of
Canada and parts of Greenland. Selection and preparation of sites is already
NAV CANADA, the country's civil air navigation services provider, is a
private sector, non-share capital corporation financed through publicly-traded
debt. With operations coast to coast, NAV CANADA provides air traffic control,
flight information, weather briefings, aeronautical information services,
airport advisory services and electronic aids to navigation.
