NOAA 17 has scan motor problems with rising motor currents. Constant rephase by the MIRP was causing data dropouts on all the HRPT stream and APT and GAC derivatives. Auto re-phase has now been disabled and the resulting AVHRR products are almost all unusable.
Please note: As of 12th October 2010 at 15:00 UTC the following APT frequencies will apply:
NOAA 17 137.500 MHz
NOAA 15 137.620 MHz
