Automatic Dependent Surveillance-Broadcast

We continue to extend air traffic surveillance coverage  by using Automatic Dependent Surveillance-Broadcast (ADS-B) to provide radar-like information at a much lower cost than radar.


Using ADS-B, we have extended our air traffic surveillance to cover 4 million square kilometres of airspace. This expansion of surveillance coverage will save airline customers an estimated $374 million in fuel costs by 2020 by enabling more fuel efficient routings, while reducing greenhouse gas emissions by about 982,000 metric tons. 

Using ADS-B

Prior to using the ADS-B service, operators should be familiar with airworthiness and operational requirements outlined in AIP Canada ENR 1.6.3. To learn more about these requirements, click here.

What’s Next

NAV CANADA is part of a joint venture, called Aireon​, with Iridium Communications and air navigation service providers from the UK (NATS), Ireland (IAA), Italy (ENAV) and Denmark (Naviair)

The purpose of Aireon is to expand air traffic surveillance to the entire planet by installing ADS-B receivers on a constellation of 66 Low Earth Orbit (LEO) satellites.

We are not only a partner in the joint venture but will be a customer when the service becomes available in spring 2019. NAV CANADA controllers in the Edmonton and Gander Flight Information Regions will be among the first in the world to use the technology, starting with domestic airspace for both regions, and followed by operational trials in the North Atlantic, the world’s busiest oceanic airspace.
