✈️ Why Monitor ADS-B Data?

Automatic Dependent Surveillance–Broadcast (ADS-B) is a surveillance technology used by aircraft to broadcast their position, speed, and other flight data in real time. Enthusiasts and aviation hobbyists around the world use software-defined radios (SDRs) to receive these signals and contribute data to platforms like FlightRadar24.

The best part? If you share your ADS-B data with FlightRadar24, they’ll reward you with a free Business account subscription (normally $499.99/year), which includes:

  • Up to 3 years of flight history
  • Access to weather layers, airspace boundaries, and detailed aircraft photos
  • A full-featured web and mobile experience
  • Premium customer support

All you need is some basic hardware, a little technical setup, and a love for aviation data. Let’s dive in.

🧰 What You Need (Prerequisites)

To get started with your own ADS-B monitoring setup, you’ll need:

  1. RTL-SDR Dongle – A USB device capable of receiving 1090 MHz signals from aircraft.
  2. Antenna – Ideally one that’s placed high and unobstructed for best reception
  3. A Raspberry Pi or Linux Machine – We’ll be running our setup using Docker.
  4. Docker and Docker Compose – Installed on your host machine.
  5. FlightRadar24 Account – To get your unique sharing key (FR24KEY).
  6. Latitude and Longitude – Your receiver’s exact location.

Tip: If you don’t have an FR24 key yet, register your hardware at fr24.com/share-your-data and request one.

📦 Setup Overview

We’re going to set up two services using Docker:

  • readsb: Listens to ADS-B signals from your SDR and decodes them.
  • fr24feed: Sends the decoded aircraft data to FlightRadar24.

📁 Create Your Project Folder

Open a terminal and run:

mkdir fr24 && cd fr24
touch .env docker-compose.yaml

📝 Configure .env File

Edit the .env file with your details:

FR24KEY=your-fr24-key
LATITUDE=your-latitude
LONGITUDE=your-longitude

Make sure to replace those placeholders with your actual info.

⚙️ Docker Compose Setup

Paste this into your docker-compose.yaml:

services:

🖥️ What Each Service Does

✅ readsb

  • Purpose: Captures and decodes signals from your RTL-SDR device.

  • Ports:

    • 8080: Web UI for live stats
    • 30005: Feeds data to fr24feed

  • Key Environment Variables:

    • READSB_LAT, READSB_LON: Your location
    • READSB_GAIN=autogain: Auto-optimized SDR signal gain

✅ fr24feed

  • Purpose: Submits your decoded data to FlightRadar24
  • Port: 8754 - Check your feed and receiver status here
  • Key Variable: FR24KEY: Your personal sharing token

🚀 Start Your Setup

With everything configured, launch the containers:

docker compose up -d

Check the logs to confirm everything is running smoothly:

docker compose logs -f readsb
docker compose logs -f fr24feed

🔍 Web Interfaces

🧪 Bonus: Test Live Aircraft Feed

Want to peek inside the raw feed? Run:

docker exec -it readsb viewadsb

You’ll see live aircraft data like this:

Hex     Flight   Alt    Spd  Lat      Long     RSSI  Msgs
4D2223  RYR59AR  40000  460  51.232   -0.980   -23.7   414
