Successful launch for start of worldwide ADS-B system

Aireon announced today the successful launch and deployment of the first ten satellites hosting its space-based automatic dependent surveillance broadcast (ADS-B) system.

Part of the Iridium NEXT satellite constellation, Aireon’s space-based ADS-B network will transform air traffic management capabilities, providing real-time air traffic surveillance and flight tracking across 100 percent of the planet. Currently, more than 70 percent of the earth, including oceanic and remote airspace, has no existing air traffic surveillance.
Aireon congratulates Iridium Communications and its partners, including Thales Alenia Space, Orbital ATK and SpaceX, on a successful first launch of the Iridium NEXT constellation, and looks forward to additional successes.

“Today is a landmark moment in history for global air traffic surveillance, air traffic safety and the aviation industry as a whole,” said Don Thoma, CEO, Aireon.

“This successful first launch brings us one step closer to changing the way the world flies by enabling the ability to track aircraft anywhere on the planet. Once our global ADS-B surveillance service is fully deployed, every ADS-B equipped aircraft can have its precise location accounted for 24/7.”

SpaceX is launching the Aireon ADS-B system with its Falcon 9 re-usable rockets.

Iridium has partnered with SpaceX for a series of seven launches over the course of 18 months out of Vandenberg Air Force Base in California. All 81 Iridium NEXT satellites are equipped with the Aireon payload.

Once in orbit, each satellite will undergo extensive testing by the Iridium team. After approximately 40-60 days Iridium will hand-off the ADS-B payloads to Aireon for verification of on-orbit technical specifications. Aireon will then conduct rigorous independent testing and validation of the space-based ADS-B system for approximately 60 days.

As part of this testing and validation process, Aireon’s ADS-B receivers, manufactured by Harris Corporation, will provide air traffic surveillance data through the Aireon network to the Service Delivery Points (SDPs) at partners NAV CANADA, NATS, ENAV, the Irish Aviation Authority (IAA), as well as the Federal Aviation Administration (FAA) William J. Hughes Technical Center in Atlantic City, New Jersey.

“Few technologies exist today that by simply reimagining their implementation can have such a dramatic, positive impact on safety, efficiency and the environment,” said Neil Wilson, president and CEO, NAV CANADA.

“Aireon is poised to revolutionize air traffic management over much of the planet, and we’re looking forward to an aviation industry where everyone will reap the benefits of 100 percent global air traffic surveillance.”

Aireon, formed by Iridium Communications and investors NAV CANADA, ENAV, the Irish Aviation Authority (IAA) and Naviair, will be operational in 2018. The advent of space-based ADS-B is expected to show a remarkable ability to increase safety and efficiency while simultaneously reducing greenhouse gas emissions.

The network will also provide a new service known as Aireon ALERT, a free global emergency-aircraft tracking service that will be hosted and operated by the IAA. Earlier this year, Aireon also announced a partnership with FlightAware, and together launched the GlobalBeacon flight tracking service. GlobalBeacon is designed to help airlines comply with the International Civil Aviation Organization (ICAO) Global Aeronautical Distress Safety System (GADSS) requirements, and will provide airlines with minute-by-minute flight tracking data.

“Many congratulations to both Aireon and Iridium on the success of their first launch,” said Juliet Kennedy, operations director for NATS. “We look forward to further successes with the remainder of the launch programme and what this will mean for operations over the North Atlantic, the world’s busiest area of oceanic airspace.”

So within a year ADS-B via the Aireon system, will provide 24/7, 100% worldwide coverage...

Yet our unique ADS-B system that is dependent on ground stations, is yet to guarantee 100% nationwide coverage:

ADS-B coverage

When operating outside of radar coverage, ADS-B derived ATS surveillance services are provided to operators of aircraft that are ADS-B Out enabled, whilst within the coverage volume of commissioned ADS-B ground stations.

ADS-B ground stations are line-of-sight facilities. The ability for a ground station to received ADS-B data from an aircraft depends on altitude, distance from the site and obstructing terrain. Coverage exists near the surface within 20 nautical miles of the ground station. High level coverage can exceed 250 nautical miles.

In airspace where ADS-B coverage overlaps radar coverage, the radar derived aircraft position will be displayed to ATC.

ADS-B only coverage charts (as at June 2016) at various altitudes are available below (click for full size image):

ADS-B coverage 5,000ft

ADS-B coverage 10,000ft  

ADS-B coverage 20,000ft

ADS-B coverage 30,000ft

Reckon there is a case for the good Senators to ask some pointed questions at the Additional Estimates public session next month...
