This guide will help you set up a NOAA Automatic Picture Transmission (APT) receiver using a Raspberry Pi 4, including optional Power over Ethernet (PoE) HAT integration and the use of a SAWbird+ NOAA filter for optimal performance. Due to recent advancements in the script, you can use a desktop computer you have laying around, but for our example we are just going to use a Raspberry Pi 4 – 8GB Model.
This guide will walk you through setting up an ADS-B receiver using a Raspberry Pi Zero and an RTL-SDR dongle to track aircraft in real time. We will use dump1090 to decode ADS-B signals and optionally feed data to services like FlightAware, ADS-B Exchange, and OpenSky Network.
