Getting NOAA sat images using an RTL-SDR

NOAA (National Oceanic and Atmospheric Administration) is the USA meteorological agency. They have a set of satellites orbiting the earth, imaging the Earth and sending it via radio. The downlink of the working satellites are on VHF so you can easily receive them. On this article, I’m sharing my experience receiving them with an rtl-sdr.


Since march 2016 I joined REP (Rede dos Emissores Portugueses), which is the national ham radio association. They have a club station in Porto, PT where they welcomed me to operate on. The callsign of the station is CS5RPT and it’s equiped for HF, VHF and the 70cm band.
