A-S was not on during this week, therefore all seven days are included in the
analysis report. Note that the higher than normal values in the orbit
repeatability table for PRN03/GPS11 at the end of the week are due to the non-
tracking of this satellite by several ground stations. See IGS Mail Message 136
for details.

WARNING: No warnings for GPS week 670.
