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 ground-based 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.

Space-based ADS-B

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)

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