A-S testing occurred during "24 Oct 92 0100 UT to 26 Oct 92 1000 UT" and
"31 Oct 92 0100 UT to 02 Nov 92 1000 UT", according to the file
pub/gps/gpstd.txt obtained from tycho.usno.navy.mil. Results for Sunday,
Oct 25, and Saturday, Oct 31, are not included in this submission. The
results for Monday, Oct 26, exclude data from Block-II satellites
acquired when operating in cross-correlated mode.
WARNING: No warnings for GPS week 668.
