The Department of Commerce, specifically the National Oceanic and Atmospheric Administration (NOAA), is issuing a Request for Information (RFI) regarding the GEONETCast Americas (GNC-A) C-BAND Spectrum to gather insights on potential technical solutions in light of upcoming changes to C-Band frequency regulations. The objective is to explore innovative solutions that can maintain the current geographic coverage and data distribution capabilities of the GNC-A program, which provides critical satellite-based weather data and emergency alerts across the Western Hemisphere. This RFI is crucial for understanding the implications of the C-Band spectrum auction mandated by recent legislation and ensuring the continuity of NOAA's mission to protect life and property. Responses are due by October 10, 2025, and interested parties should contact Andrea Chiodi at andrea.chiodi@noaa.gov or Jame Chang at jame.chang@noaa.gov for further information.
