I used ADS on the Pacific in 2005 so it was available here and about the same time in Alaska, Asia, then Iceland & Shannon. I asked this question on about page 6 or so of the other thread precisely because ADS would have provided lat/long information as well as speed, altitude etc but the thread was moving pretty quickly...
I don't know how often ADS squirts it's reports out. Apparently however, (learned from this thread) that ADS is still "on trial" in the area AF447 was so we may or may not have that info - depends upon whether the AF crew logged on or not. (Perhaps the absence of ADS in some areas of the world still is what wings 1011 means?)
