Iridium's Next Generation Satellite Network will Search for Missing Planes at No-Charge

As reported by GigaOM: When Iridium’s new satellites will start blasting into orbit next year on top of SpaceX and Dnepr rockets, they’ll be carrying a special payload: an aircraft tracking system that will be able to locate a plane anywhere in the world once Iridium’s 66-satellite constellation is fully operational in 2017.

The service is run by Aireon, a joint venture between Iridium and government aviation agencies in Canada and Europe, and it plans on charging airlines for its core flight monitoring services. But Aireon said it would open the network up gratis to international rescue agencies during emergencies, allowing them to home in on missing aircraft.

In the case of Malaysia Airlines 370, which disappeared in March, the emergency service could have helped in locating and the possible rescue of the still-missing flight by plotting its exact GPS coordinates every few seconds. The technology behind it is called Automatic Dependent Surveillance-Broadcast (ADS-B), and transponders using it are being installed in new and old commercial aircraft.

Iridium birds won’t be the only ones listening for ADS-B signals either, both Inmarsat and Globalstar are putting the locator tech on their aircraft and will be offering competing flight monitoring services. Iridium, however, has the slight advantage of offering pole-to-pole coverage, which given the artic great circle routes taken by many transcontinental flights, would be very handy.
