Whoopee. I always wanted gps to lead me to success.

Looks like Andersen has been completely wrong about GPS clocks all along.
Contrary to what he has always insisted, the clock rates are easily and
regularly adjusted after launch.

Inspection of the differences
between UTC/TAI and the phase of each NAVSTAR
GPS clock enables the USNO to identify GPS clocks that
require particular frequency-rate control corrections. Use of
this knowledge enables the USAF to adjust frequency rates of
selected GPS clocks. Currently the USAF uses an automated
bang-bang controller(3) on frequency-rate.
