NESDIS is preparing to replace a GOES-N series satellite with a GOES-R series satellite.
NWS is consolidating the management of dissemination services, under a program called the Integrated Dissemination Program (IDP)
IT Security threats require NOAA to periodically updating controls and procedures to minimize the risk of potential EMWIN operational impacts.
Improved data products for hemispheric re-transmission
Requires new antenna and receiver hardware
Documents and updates to be posted on the GOES-R web site:
