High Rate Information Transmission (HRIT)

The High Rate Information Transmission (HRIT) is an evolution of two existing data platforms, the legacy Low Rate Information Transmission (LRIT) and the Emergency Managers Weather Information Network (EMWIN) that’s currently two separate transponders onboard GOES-NOP series satellites. HRIT/EMWIN will be consolidated into one transponder on the GOES-R series satellites that will broadcast NWS warnings/watches, environmental charts, both GOES and Himawari imagery, and a re-broadcast of GOES DCS observations at a rate 3 times faster than the legacy LRIT system. Users can purchase or upgrade the necessary equipment (computer, software, antenna and receivers) from commercial companies for unlimited access to both HRIT and LRIT signals. There is no fee or license requirement by NOAA to receive this data.
