NOAA-14 Successfully Switched Back to Nominal Control Mode

On September 21, NOAA-14 was successfully commanded back to Nominal
ADACS control mode on rev 34676 / Fairbanks at 1740z . The NOAA-14
ADACS subsystem was placed in YGC control mode since September 8, 2001
due to blockage of the sun sensor field of view by the solar array. The
skew gyro was also selected to replace the X (yaw) gyro at the same time
due to the bad yaw updates from the blocked sun sensor. The sun sensor
blockage has been eliminated by the reduction of solar array offset that
was performed on September 18, 2001. Hince, it was possible to return
the ADACS subsystem to the NOMINAL control mode and to reselect the
orthogonal set of gyros.
