This started as a home weather station project, so far I've gotten as far as the satellite image downloading system. Adding local weather sensors will probably be a future video. So far, the system is set up to automatically receive NOAA and METEOR-M2 satellite transmissions and display the weather maps in a web panel. Along the way I had to rebuilt my satellite antenna, upgrade my Raspberry Pi computer, and get a bigger waterproof housing to fit all the equipment.
Some resources I used for this project include:
-QFH antenna guide: usradioguy.com/noaa-apt-recept...
-Instructables guide: www.instructables.com/Raspber...
-Code for automating the entire process: github.com/jekhokie/raspberry...
-Reddit and the helpful users on / amateursatellites and / rtlsdr
Some issues I ran into:
-Raspberry Pi's don't have a clock... so if you're doing this off-grid or somewhere without always-on internet you'll need an add-on clock module.
-My SDR doesn't seem to work with rtl_fm's -T option, so I had to manually enable and disable the Bias-tee as described here: www.rtl-sdr.com/rtl-sdr-blog-...
