A-S testing occurred during "21 Nov 0100 UT to 23 Nov 0100 UT" and
"28 Nov 0100 UT to 30 Nov 0100 UT", according to the file pub/gps/gpstd.txt
obtained from tycho.usno.navy.mil. Results for Sunday, Nov 22, and Saturday,
Nov 28, are not included in this submission. The results for Monday, Nov 23,
exclude data from Block-II satellites acquired when operating in
cross-correlated mode.
The repeatabilities for PRN11/GPS08 increase during the week, and by Friday are
about an order of magnitude larger than usual.
WARNING: PRN11/GPS08 has atypical 3drss values toward the end of GPS week 672.

defined in IGS Mail Message 37, for GPS week 672:
