Global Space-Based ADS-B Flight Tracking
"FlightAware and Aireon are proud to announce the world's first and only global, space-based ADS-B flight tracking solution. FlightAware's technology and Aireon's 66 ADS-B receivers in low earth orbit will forever change the world of flight tracking and flight safety. (flightaware.com)"
https://flightaware.com/aireon/ This will be a direct competitor to Delorme InReach and Spot tracking services used by sailplane pilots today ....of course... you'll have to have ADS-B out installed. But, depending on the cost of this service, it could ultimately be less expensive than paying $250-$400 per year for Delorme (However.. it might be more expensive!). My Trig T22 equipped glider can probably be upgraded to ADS-B out for $600. It has to be checked every two years by an avionics shop (but that should be done for the Mode S transponder anyway).

Walt Rogers WX Walt, Very interesting....One reason (among perhaps several) to perhaps stay with a Delorme InReach (or a SPOT) is that I use my InReach for not only soaring, but also for hiking & camping trips. It can also be used in any aircraft or glider and I know some folks use it for boating and for other outside activities. That being said, I do believe we will see many rapid advances in this area over the next few years. Thx - Renny |

Global Space-Based ADS-B Flight Tracking
What about the time delay between ground and geostationary satellites? I once helped get an initial STC to put a Satphone in a Lockheed JetStar and I can tell you there is a noticeable delay when you are bouncing signals from low altitude to space and back. Not a huge delay, mind you, but enough to make carrying a simple conversation a little awkward. When we are expecting near-instantaneous position communications between aircraft and satellites, could the delay be substantial enough to skew the warnings?

When we are expecting near-instantaneous position communications between aircraft and satellites, could the delay be substantial enough to skew the warnings? I see the use of the satellite based collection of ADS-B location packets for high resolution tracking of sailplanes... not as a collision advisory/avoidance system. The time delay round trip to satellites might be an issue there... but not high resolution real-time tracking. One second updates could produce some fairly realistic real-time viewing of gliding contest and activities. I'm not as interested in the intended use for a global Air Traffic Control services ADS-B based system. BTW, There still would be use for the Delorme Inreach in sailplanes. It's a good emergency services unit that can be attached to a parachute and provide text message/email services from anywhere on the ground or in the air. Although, there wouldn't be a need to the 1 or 2 minute tracking intervals.... 5-10 minutes would be sufficient... if the ADS-B tracking from the glider were logged somewhere for use in emergency location services.
