Nav Canada To Launch ADS-B in Remote Areas
Nav Canada announced last week it plans this year and next to install ADS-B ground stations around Hudson Bay, which straddles high-latitude airline flight paths linking Asia, North America and Europe, but which has no radar coverage. Currently, aircraft overflying the area must observe “procedural” separations that keep them about 80 miles apart, compared with five miles under radar monitoring. Some 35,000 flights transit Hudson Bay each year. Nav Canada said ADS-B will save operators more than C$200 million in reduced fuel costs over 15 years. Following the Hudson Bay installations, ADS-B will be extended to cover other remote areas across northern Canada that lack radar coverage. Subsequently, systems will be installed in southern Canada, to link to FAA installations along the border with the U.S., with the long-term aim of phasing out conventional ATC radar. Sensis won the contract to install the stations.
