A-S testing occurred during "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, Nov 01, are not included in this submission. The results for Monday,
Nov 02, exclude data from Block-II satellites acquired when operating in
cross-correlated mode.

WARNING: No warnings for GPS week 669.
