About these Images

The images above are sourced from one of the GOES weather satellites parked in geostationary orbit at the GOES-East location. Previously this was GOES-16 and going on from April 2025 is GOES-19, both of the GOES-R variety. The GOES-R satellites include a High-Rate Image Transmission (HRIT) broadcast on 1.6941 GHz, which can be received by low-cost software defined radios and a small parabolic dish. For high-fidelity reception and long-term stability, I utilize a Noelec Sawbird GOES filter and low-noise amplifier centered on 1.7GHz coupled to a 1.5GHz Ham-it-down downconverter. The downconvert to 194.1 MHz helps to minimize loss in 15m of RG-58 coax leading back to an RTL-SDR v4 dongle, which is more than capable of receiving it directly. Satdump is used in CLI mode to capture and decode the HRIT signal, while some bash scripts stage the images for viewing as they are received and decoded. This is a simple Javascript-powered static HTML page for viewing the results.
