Topic:
Solar Array Move May Cause Data Shifts
Date/Time(UTC) Message Issued:
10 July 2003, 1900 UTC
Satellite(s) Involved:
NOAA-12
Instrument(s) Involved:
All instruments
Product(s) Involved/Affected:
All Products/increase charge currents and possible thermal profile
changes
Date/Time(UTC) of Initial Implementation:
10 July 2003, Time 1430 UTC
Details/Specifics of Change:
On July 10, SOCC changed the solar array offset from -30 to -45 degrees.
According to SOCC, "This change will reduce excess power production by the
solar array, and therefore reduce operational stress on the power
dissipation shunts. Some change in thermal profile due to differences of
array shading of various spacecraft components is possible". Users may
notice data changes.
