*Topic: GOES-16 ABI EOPP Navigation Update scheduled for April 27,
2018Date/Time Issued: April 25, 2018 1335 UTCProduct(s) or Data
Impacted:
GOES-16 ABI EOPP Navigation UpdateDate/Time of Initial Impact:
April 27,
2018 1915 UTC Date/Time of Expected End: April 27, 2018 1930 UTC
Length of
Outage: Approximately 15 minutes of degraded productsDetails/Specifics
of
Change:On Friday, April 27, 2018 at 1918 UTC the GOES-16 routine weekly
upload of Earth Orientation Parameter Predictions (EOPP) will be
modified
to correct for a processing discrepancy onboard the spacecraft. Imagery
acquired during this time (Full Disk, CONUS, and MESOs) will be
affected in
the following way: There will be a slight change in navigation (<10
microradians or 400 meters) in the EW direction within 2 minutes of the
upload. After verifying successful EOPP upload to GOES-16, the
ABI lookup
table (LUT) changes necessary to remove the EW bias from the ground
processing will occur. By the start of the GOES-16 ABI Mode 3
timeline at
1930 UTC both the spacecraft and ground processing should be
synchronized
for proper ABI image navigation.  If there is a Critical Weather Day
declared on Friday then the GOES-16 modified EOPP load will be
postponed. Contact Information for Further Information: ESPC
