Scientists investigate GOES-17 Advanced Baseline Imager performance issue
(23 May 2018 - NOAA) The GOES-R Program is currently addressing a performance issue with the cooling system encountered during commissioning of the GOES-17 Advanced Baseline Imager (ABI) instrument. The cooling system is an integral part of the ABI and did not start up properly during the on-orbit checkout.
A team of experts from NOAA, NASA, the ABI contractor team and industry are investigating the issue and pursuing multiple courses of possible corrective actions. The issue affects 13 of the infrared and near-infrared channels on the instrument. At this time, we do not believe that the three channels with the shortest wavelengths, which includes the visible channels, are significantly affected.
NOAA’s operational geostationary constellation -- GOES-16, operating as GOES-East, GOES-15, operating as GOES-West and GOES-14, operating as the on-orbit spare -- is healthy and monitoring weather across the nation each day, so there is no immediate impact from this performance issue.
If efforts to restore the cooling system are unsuccessful, alternative concepts and modes will be considered to maximize the operational utility of the ABI for NOAA's National Weather Service and other customers.
