NOAA-15
Instrument(s) Involved:
All
Product(s) Involved/Affected:
All data users
Date/Time(UTC) of Initial Implementation:
9 January 2003 1705 UTC
Details/Specifics of Change:
SOCC has issued an information bulletin announcing the following change
on
Jaunuary 9, 2003.
"The analog telemetry on NOAA-15 is drifting upwards at a rate of one
count
approximately every 150 days. The current value is beginning to generate
yellow limit violations and close in on the red limits. To rectify
this
situation, the TIP is to be switched from side 1 to side 2. .... On
January
9th, 2003, we are planning to switch NOAA-15's TIP from side 1 to side
2.
We have scheduled a pass with no playbacks of recorded data so that
we have
time available to ensure that the switch occurred nominally. However,
since
the TIP switch will affect all telemetry and data, we will lose instrument
recordings for part of the contact. Most likely on the order of 5 -
10
minutes of data lost. The pass is scheduled for Jan. 9th at 1705Z,
or 12:06
pm EST."
