Topic: GOES-14/15/16/17 Spring 2023 Solar RFI predicted times are now available
Date/Time Issued: March 1, 2023 1332 UTC
Product(s) or Data Impacted: GOES-14/15/16/17 Imager and Sounder Data plus Ancillary Services (GVAR, SAR, LRIT, EMWIN, DCS, GRB, etc.)
Date/Time of Initial Impact: February 23, 2023 2034 UTC
Date/Time of Expected End: March 9, 2023 2151 UTC
Length of Outage: See table in details.
Details/Specifics of Change: The potential for solar radio frequency interference (RFI) with a satellite downlink circuit will occur whenever the Sun passes into the beam of the ground station receiving antenna.
We received the following information from our Mission Operations Division concerning the potential for outages of the GOES data stream including GVAR (GOES Variable) Imager and Sounder, SAR (Search and Rescue), High Rate Information Transmission (HRIT), Sensor Data (SD), Telemetry and Command (T&C), Weather Facsimile (WEFAX), Data Collection Platform Report (DCPR), Multi-use data link (MDL), Raw Data Link (RDL), etc.
The Wallops and Fairbanks Command and Data Acquisition Stations (CDAs) and Environmental Satellite Processing Center (ESPC) receiving antennas may experience periods of Solar RFI as predicted below. Solar RFI can cause loss of telemetry lock and command capability, as well as degradation or loss in the GVAR data.
