--047d7b2e79c882e6d704cd8d32c9
Content-Type: text/plain; charset=ISO-8859-1
Topic: NOAA-17 Data Transmission Change
Date/Time Issued: November 3, 2012 0130 UTC
Product(s) or Data Impacted: NOAA-17 GAC Data & NOAA-17 HRPT Data
Date/Time of Initial Impact: November 6, 2012 0000 UTC
Date/Time of Expected End: This configuration change is effective
until
further notice.
Length of Outage: N/A
Details/Specifics of Change: Due to the loss of S-Band Transmitter #1
(STX1) on NOAA-17, a new data transmission configuration is being
promoted. The new configuration will move HRPT broadcast from STX1
to STX2
(1702.5MHz) in order to allow for the continued collection of
spacecraft
health and safety information. The new configuration also includes a
schedule change that will impact the transmission of NOAA-17 GAC
(Global
Area Coverage) data and prevent the recovery of all GACs. Whereas
GAC was
previously dumped from two transmitters, it will now be dumped by
only one
transmitter. Typically, 2-3 GAC dumps occur during each of 6-8
passes per
day. The same is true going forward, but with the restriction of
delivering those dumps with only one available transmitter there may
be a
reduced number of GACs recovered.
Here is the current transmitter status:
STX1 L-Band Transmitter #1 (1698MHz) Status is Orange
STX2 L-Band Transmitter #2 (1702.5MHz) Status is Green
STX3 L-Band Transmitter #3 (1707MHz) Status is Red
STX4 S-Band Transmitter #4 (2247.5MHz) Status is Green
Impact to Products: The benefit of this configuration change is
that it
allows for continued nominal transmission of HRPT data for the
Argos Data
Collection System. Only products that rely on NOAA-17 GAC data will be
negatively impacted. The impact to Blended Total Precipitable Water
(bTPW)
will be a twice per day, 80 minute degradation of the refresh rate.
Ozone
products will also see an impact due to the lack of NOAA-17 GAC data.
