Garmin and the D



So the page in most Garmins that shows the birds puts a little D on
those birds that are "WAAS" enabled/complient/whatever. [This is almost
enireally undocumented in the Garman isntructions, but...]

What's that mean? See, I always thought all DGPS schemes corrected the
calculated position equation results, not the individual birds.

Is that wrong? Does WAAS say "Bird 123 is wrong by Z nanoseconds" etc?
And if the correction is applied in the rx.....why aren't older birds as
correctable as new ones?
