In order to run the server, you need .env (see .env.example) and flight_data.json (which is your JSON database for APRS flight data). The server should start running with yarn serve. Go to localhost.com:8000 to see the 3D tracker, and start sending APRS packets via TCP to localhost.com:3000 in the same format used to upload to APRS-IS.
touch flight_data.json
cp .env.example .env
yarn serve
This server is designed to make use of GNU Radio's gr-ax25 OOT module by dl1ksv to demodulate the APRS packets. Since a custom flowgraph is needed, use our forked version instead. We have created a flowgraph for you to use if you connect your HT to your computer via an audio cable.
You may expect your 3D flight tracker to look something like the images shown below.
