Here is another take on Friday's meeting.

"Question: How is the fix for this problem modeled? Is it a constant
bias or something else?
Answer: (Madden) The fix effectively moved the antenna phase center
for the satellite to 150 meters behind the satellite.
Question: What navigation parameters are being changed to implement
this fix?
Answer: (Thomas Powell, Aerospace) The ephemeris phase center value
(later determined to be the Tgd value) and the clock offset values are
being modified to allow user's receiver to get a correct URE for this
satellite."
With an elevation dependent error, I wonder how this is supposed to
work. Anybody?
BTW, AFSpace is on Twitter.
