• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Hello!

Can this System in the future be the end of HF Communication across the Atlantic Ocean?? ( Gander - Shanwick Aircontrol Center )

I have no idea as I just found about it myself. My guess is they'll go with satellite when ever possible for almost every thing in the future.

I have a feeling that HF will eventually go away with the emergence of Satcom. I know most the Jetblue 320s and 321s are equipped with Satcom capaibiliy. Not sure about the 190s.

So I hope I can receive with my own Equipment ADS-B signals via satellite from the North Atlantic Region in the future! ( like Inmarsat Acars )

I doubt it. This system allows the controllers to track the aircraft, not talk or CPDLC to them at the moment - there is no two-way communication via the tracking satellites. Even CPDLC has it's failures occasionally and they have to revert to HF which is why the aircraft using CPDLC still have to carry out a handover procedure when crossing the control boundaries and carry out a Selcal check.

So I hope I can receive with my own Equipment ADS-B signals via satellite from the North Atlantic Region in the future!
I doubt that the satellite will be re-broadcasting the ADS-B signals on an aircraft band frequency - more likely to be up in the GHz bands and with antennas pointing at the ground station. With 66 satellites around the world and 22 and maybe more over the horizon at any one time, how are they sorting out which satellite got the signal and reported the data 'back to base'. A satellite can't send it's own interrogation signal and have every aircraft in it's view respond. I've dumped all my ADSB/TCAS books but isn't the maximum range that generates a response about 75nm?
