Isavia ANS, Iceland’s Air Navigation Service Provider (ANSP) will use Aireon’s space-based Automatic Dependent Surveillance-Broadcast (ADS-B) system in their 5.4 million square kilometers of controlled airspace, making it one of the largest deployments to-date. Isavia ANS provides air navigation services that span the North Pole to Scotland, and from the Greenwich Meridian in the east to west of Greenland. Aireon’s system extends Isavia’s current ground-based air traffic surveillance framework, focusing on enhancing real-time air traffic surveillance in the corridor connecting Europe and North America to all customers. Isavia’s initial use of Aireon’s space-based system is in all airspace south of 70 degrees north, providing coverage to those sectors. Aireon’s system is not only extending Air Traffic Service (ATS) surveillance in oceanic airspace, but it also represents an ideal solution for a region where weather disruptions can create issues and ground sensor maintenance is a challenge.
