Weather Image Dumps from NOAA Satellites
Weather image dumps from various NOAA satellites using a simple RTL-SDR and a QFH antenna.
The following gear was used to decode the APT signals from various NOAA satellites:
- RTL-SDR
- QFH antenna tuned to 137 MHz
- 1 MHz – 3 GHz wideband LNA
- A Raspberry Pi for handling the exquisiteness of the RTL-SDR
- And a dumb PC for decoding the APT signals
Attempt 1 — NOAA-19, 24/05/2018 19:41. Even I’m not sure what this image is supposed to mean :P
Attempt 2 — NOAA-19, 25/05/2018 04:00. The APT signal was too noisy despite the LNA, but the decoder still managed a pretty good image.
Attempt 3 — NOAA-19, 25/05/2018 16:40. Third time’s the charm — finally an image I’m proud of xD
Attempt 4 — NOAA-18, 25/05/2018 17:20. A little noisy, but WXtoIMG managed to figure out the pass and build an overlay.
Attempt 5 — NOAA-19, 27/05/2018 05:12. Captured the APT signals of the satellite pass completely, with noise at both the start and end, which decodes to this beautiful piece of image.
