Nav Canada intends to add to its oceanic ADS-B surveillance by putting a ground station on the Hibernia off-shore oil platform, and an agreement with the platform's owners is expected soon.
Other ANSPs are also extending Atlantic ADS-B coverage. Iceland's Isavia and Denmark's Naviair are working on a connected series of ADS-B stations in the Faroe Islands, Iceland and Greenland that is intended to provide a surveillance corridor from European to North American airspace (AW&ST Oct. 22, 2012, p. 41).
This corridor will be farther north than routes for the bulk of the transatlantic traffic that Nav Canada and NATS are responsible for, but it will still cover some important traffic flows.
Isavia is responsible for installing the Iceland network—which largely overlays existing radar coverage—while Naviair is responsible for the Greenland and Faroe Islands sites. Isavia will provide high-altitude ATM services across all of these networks from its Reykjavik center.
This was originally intended to be a joint procurement project, but Naviair opted to pursue its own contract process for the Greenland ADS-B sites. Isavia selected Comsoft to provide its ADS-B stations, which have already been deployed and tested. They are expected to be used operationally this summer. Naviair, meanwhile, awarded a contract to Saab Sensis. Installation is expected this summer with surveillance data being transmitted by year-end. Limited operational use could begin in 2014, Isavia says.
