Topic:
Cooling Scan Motor to Improve Performance
Date/Time(UTC) Message Issued:
15 January 2004, 2245 UTC
Satellite(s) Involved:
NOAA-16
Instrument(s) Involved:
AVHRR, HIRS
Product(s) Involved/Affected:
Possible improvement in AVHRR/May affect HIRS filter motor temperature
Date/Time(UTC) of Initial Implementation:
16 January 2004, Time 1222 UTC
Details/Specifics of Change:
On January 16, around 1222, SOCC plans to turn the TCE-24 (Heater/Louver)
back on. The AVHRR is running at record high temperatures. The scan motor
surged to high values and imagery has degraded significantly (bar code
pattern). It is believed that the scan motor operates better when cooler.
Hince, the louver will be turned back on.
We may see improvement in the AVHRR scan motor performance and probably a
minor decrease in the HIRS filter motor temperature and current.
Temperature may drop by 0.5 degrees and current by 2 to 4 mAmps over a day
or two.
