Dropping OpenSky to Receive It Myself — Feeding RTL-SDR ADS-B into My Terminal Globe ttymap
Earlier I wrote about building ttymap, a globe you spin inside the terminal. A braille-character globe with planes, earthquakes, the ISS and more layered on top. The aircraft plugin that shows those planes hit OpenSky Network's public ADS-B feed. Handy, but really you're just watching the result someone else's server received and formatted. The radio those overhead planes emit is raining down on my own room right now too. So I'd rather receive it on my own antenna and put it on my own globe.
