Satellite Airliner Tracking Over Oceans Goes Global (bbc.com) 57

dryriver shares a report from the BBC: Tracking airplanes anywhere in the world just got a lot easier. The U.S. firm Aireon says its new satellite surveillance network is now fully live and being trialled over the North Atlantic. The system employs a constellation of 66 (Iridium) spacecraft, which monitor the situational messages pumped out by aircraft transponders. These report a plane's position, altitude, direction and speed every eight seconds. The two big navigation management companies that marshal plane movements across the North Atlantic -- UK Nats and Nav Canada -- intend to use Aireon to transform their operations. The more detailed information they now have about the behavior of airplanes means more efficient routing can be introduced. This ought to reduce costs for airlines. Passengers should also experience fewer delays. Aireon has receivers riding piggyback on all 66 spacecraft of the Iridium sat-phone service provider. These sensors make it possible now to track planes even out over the ocean, beyond the visibility of radar -- and ocean waters cover 70% of the globe. The rapid-fire nature of the messaging also means aircraft visibility is virtually continuous. Existing data links only report ocean-crossing aircraft positions every 14 minutes. '

    It seems ships have had a decent tracking system in place for a while now. See https://www.marinetraffic.com/ [marinetraffic.com] .. many update every 2 minutes.
    With planes I could track almost real-time a relative's long-haul flight. So something already exists for aircraft too. The change here must therefore be that the ping is wired-in mandatory and not subject to a pilot flipping the switch to off.

      Any radio must have an hard off switch. What do you do when radio malfunctions and starts smoking or broadcasting gobbledygook all over the spectrum? That happens a lot more often than pilot maliciously turning transponder off and wanting to fly all sneaky like. By the way, if a pilot decides to suicide by crashing an airplane, then knowing where the plane is doesn't really help you, you still can't do squat about it.

      What this system provides is global coverage of ADS-B receivers, that's all.

      I guess it's easier to have a nice big antenna on a ship. Aircraft need to consider aerodynamics and increased fuel consumption when attaching anything like that.

      If you can have a nice big antenna you can use lower frequency, longer range signals and avoid the need for expensive satellite comms. Or you could have fewer satellites to get the same coverage.

      I'm just guessing.

    • The change is that this used to be an upsell from the manufacturer. Upsells have a bad rap these days.

    • They’ve had it as an option for planes for more than a decade but airlines had to buy it as a service. Airbus I think sold it as part of a maintenance package where the plane would not only send its location but any service faults so that maintenance crews could be alerted before the plane landed. Budget airlines would however never purchase such options.

        It probably should have been made mandatory for flights involving many passengers some time ago.

        • But that’s regulation and good luck getting that passed. Also using satellite tracking involves having and deploying satellites which isn’t free. Costs are something like $20-30M per launch not including the cost of the satellite.

            The US government has been keeping Iridium around for its own purposes, so it's been available for tasks just such as this all along.

            • Are we talking about the same thing? Iridium is a private satellite collection originated from Motorola for satellite voice and data and not tracking. While you can use the satellites for this purpose, they use a different band than the current ADS-B. Somehow someone has to pay for dozens of satellites required.

                Iridium is semi-public because they went bankrupt years ago and the DoD bought up a lot of the assets. They do have a commercial division and you can still get Iridium phones and pagers (and modems).

    >US and European regulators have mandated all aircraft carry this equipment as of next year. Surely with the exception of all military planes, a bunch of CIA-owned planes and a bunch of private planes owned by the dark state puppet masters.

      Most of these military birds carry some sort of gear like this although the Russian recon birds sometimes turn it off and fly through the commercial air lanes just to ruin your day and royally piss everybody off. If you are worried about the 'gubbermint' and their grey alien overlords tracking you, you can try wrapping your plane in aluminium foil :-)

    Nav Canada was privatized by the Canadian government about 25 years ago and it's been hitting homeruns ever since.

    The US federal government could learn from this great example.

    Excellent. VERY much needed. Not knowing where an aircraft was when it crashed was weird.

    • The satellites rely on planes transponders. The MH370 had its transponder disabled, and that network wouldn't have helped.
  • When we get this for automated cars, self-driving may actually work! And they don't even need to cover the oceans!
