Aireon announced a successful eighth and final launch and deployment of the Iridium NEXT satellite constellation hosting the Aireon space-based Automatic Dependent Surveillance-Broadcast (ADS-B) payloads. At 7:31:33 AM PST (15:31:33 UTC) a SpaceX Falcon 9 rocket lifted off from Vandenberg Air Force Base in California (US) and placed the final 10 Iridium NEXT satellites into low earth orbit (LEO). This launch brought the total number of Aireon payloads in orbit to 75 (66 operational payloads and 9 spares), completing the historic launch program and passing one of the last remaining milestones before Aireon ushers in a new era of global air traffic surveillance and aircraft tracking.
Aireon is the world’s first 100% global air traffic surveillance system and is revolutionizing the way the world travels with space-based technology. Unlike existing aircraft surveillance and tracking infrastructure, the Aireon system uses space-based ADS-B technology, which enables the automatic and real-time collection of aircraft position data. The Aireon technology gives air traffic controllers and airlines a complete and comprehensive view of the entire sky, like never before. With this upgraded insight into the world’s flight paths, including those in remote and oceanic airspace, the entire industry will experience significant direct and indirect benefits such as, increased safety, more efficient flight routes, more accurate arrival and departure predictions, faster emergency response times, reduced aircraft separation, a decrease in CO2 emissions and more.
Thus far, the Aireon system has out-performed all predictions and is processing more than 13 billion ADS-B messages per month, with that number expected to grow upon full deployment. Air traffic controllers rely on the best and most accurate surveillance data possible to separate aircraft, which is often achieved through multiple redundant layers. Aireon’s data will provide air traffic controllers with a fully redundant data feed that covers the entire airspace, increasing the availability and reliability of a critical component in air traffic management, with a positive impact on safety and efficiency. This will in turn, help improve flight optimization by eliminating gaps in fleet data reports, and ultimately enhance the overall safety, accuracy and efficiency of worldwide air travel.
A total of 81 Iridium NEXT satellites have been built, all of which have the Aireon payload onboard. There are now 75 satellites deployed, with nine serving as on-orbit spares and the remaining six as ground spares. The recent launch marks the completion of the Iridium NEXT launch campaign, successfully deploying the full Aireon system.
