It's not really surprising the USA are getting it. Shanwick and Gander have been using CPDLC for years. New York oceanic has had it for a while and even Algiers uses it.
Mind you it would be nice to have the whole of Africa covered by it and universally controlled by a competent authority. That way it doesn't matter if the Djamena and Lubumbashi controllers go home at night. Ahh well I can dream.

Been using it in KZAK and PANC airspace for a couple of years at least with no problems. Level changes and even block levels are given readily making it very economical to operate. 14 hour crossing of the Pacific Ocean with one HF call at 150W, bliss.

Should I be cynical about the timing of all this ? Would anybody like to bet that the current regime at the FAA is trying to get some contracts signed before the Obama Administration comes in and cleans house ?
Keep your eyes on Bobby Sturgell & Co. next year and see where they wind up.

How exactly are they identified?
Have you ever been warned by Shannon of Russian carriers and associated air activity when on the north atlantic tracks or other unauthorised military penetration of North Atlantic airspace?
Have you ever heard of a Mode C error causing erroneous TCAS advice?
Still, 999 times out of 1000 your assumption will be correct, I guess that's safe enough for you.

The article seems to confuse ADS-B with ADS-C (the latter being satellite-based, the former using radar frequencies and a network of ground stations).
60 mile separation on the ocean does seem a lot, but less than 50% of aircraft on the North Atlantic are currently capable of automatic reporting of satellite derived positions and receiving instructions over the much more reliable satellite communications channels. There is also some evidence that, even when they get through, not all reports received over the Ballygirreen HF radio link are totally accurate, so manual reporting cannot be relied on for reduced separation.

It will be interesting to see if the Aircraft get any better service for the money it will cost for the increase in polling. Those Sat position reports are not cheap. If the system allows the ATC facility to set the polling rate and the Airline has to pay the bill, why would the ATCO not put it at maximum. Who cares what it costs the airline. There are alot of issues to be ironed out. The Airlines are going to want and see a cost benifit before they start sending $2 position reports by sat every minute or more.

ADS-B ground stations can go anywhere,...
I notice in the Gulf of Mexico they'll be on oil rigs. Wonder what happens when the oil rigs move ? If I remember correctly, the FAA has already tried sea buoys.

Even in the middle of the North Atlantic ? Can't wait to see that.
However, we are talking about continental, not oceanic, control!
The rig installations are needed in the Gulf of Mexico because the northern area is counted as domestic airspace. It doesn't matter if the host rigs are moved, as long as there is still overlapping coverage in the area of interest. It's a lot easier than using them as radar sites as you don't need to recalibrate the processing systems if the antenna is moved.

Here in Australia, where we have both ADS-C (Contract) and ADS-B (Broadcast) when it comes to ADS-C the minimum time we can establish between position reports is 5 minutes - and we only do that in an emergency - otherwise the default reporting rate is 30 minutes. We know that everytime a report comes down it costs the airline money.
We DO NOT see how many times in one minute we can set it off!

You're welcome Pelton. But it's nothing new.

Makes you wonder what we could do with today's technology. It's amazing how much money we can spend on defense -- but can't on infrastructure.
