Peter,
Our GPS program cannot tell the difference between WAAS and Egnos so
for the moment, we announce WAAS when a corrected signal is apparent.
I have experienced WAAS many times over the years in Europe. However,
the signal was not actually being corrected. Only the EGNOS satellite
signal was picked up but not ground correction data was being used yet.
We explain this in our documentation but it isn't something anyone
would notice easily. When EGNOS finally goes live and the correction
is active, then you can enjoy the improved accuracy as good or better
than the WAAS in the U.S.
I have also gotten a WAAS reading in New Zealand or Australia, I
forget which one and that too is not a truly corrected signal.

Hi All,
A few weeks ago I posted to say that for the first time ever in the
UK , Sendero was reporting WAAS, with best accuracy that day of eleven feet.
Since then, to my great disappointment, there has been no sign of
WAAS. I finally found a European Commission document which
explained that EGNOS, which is the European version of WAAS, had
been delayed, but was due to go live in early 2008, so it seems that
they may have been testing it on that day. The document also
explained that Galileo, which is the full rolll-out of thirty
satellites to give coverage equivalent or better than existing GPS,
had been very much delayed, and now looks like going fully live
somewhere around 2012, if it doesn't hit further economic and
logistical problems.
For the moment I'm just looking forward to regular EGNOS, because
the improvement was seriously useful.
Best,
Peter
