Feeding FlightRadar24

If you wish to feed FlightRadar24, follow the steps below.

FlightRadar24 is a global flight tracking service that provides real-time information about thousands of aircraft around the world. Their service is currently available online and their mobile app is quite good. In order to access the features of the mobile app, you'll need to feed your ADS-B data to them for a free business plan.

fr24 is a FlightRadar24 client program to securely transmit ADS-B and Mode S data to the commercial entity FlightRadar24.

We've created a docker image ghcr.io/sdr-enthusiasts/docker-flightradar24 that contains fr24 and all of its required prerequisites and libraries.

Getting a Sharing Key

Already running fr24?

You'll need your fr24key from your existing feeder.

To get your fr24key, log onto your feeder and issue the command:

cat /etc/fr24feed.ini | grep fr24key

You can also find it in the data sharing section on the fr24 website if you have an account with the email address that was used when creating the key.

New to fr24?

If you're already feeding FlightRadar24 and you've followed the steps in the previous command, you can skip this section.

First-time users should obtain a FlightRadar24 sharing key (a fr24key). To get one, you can run through the sign-up process. This will ask a series of questions allowing you to sign up with FlightRadar24 and get a fr24key. Use the same email address as for your fr24 account if you already have one or plan on creating one.

Obtaining a Sharing Key for ADSB

Run the command:

docker run -it --rm ghcr.io/sdr-enthusiasts/docker-baseimage:qemu bash -c "$(curl -sSL https://raw.githubusercontent.com/sdr-enthusiasts/docker-flightradar24/main/get_adsb_key.sh)"

This will start up a container. After installing a bunch of software (which may take a while depending on the speed of your machine and internet connection), it will take you through the sign-up process. Most of the answers don't matter as during normal operation the configuration will be set with environment variables. I would suggest answering as follows:

  • Step 1.1 - Enter your email address (username@domain.tld): Enter your FlightRadar24 account email address

  • Step 1.2 - If you used to feed FR24 with ADS-B data before, enter your sharing key.: Leave blank and press enter

  • Step 1.3 - Would you like to participate in MLAT calculations?: Answer no

  • Would you like to continue using these settings?: Answer yes

  • Step 4.1 - Receiver selection (in order to run MLAT please use DVB-T stick with dump1090 utility bundled with fr24feed)... Enter your receiver type (1-7): Answer 4.

  • Enter your connection type: Answer 1.

  • host: Answer:

  • port: Answer: 30005

  • Step 5: Answer: no twice.

Note that there is a limit of 3 feeders per FR24 account. ADSB and UAT (see below) each count as 1 feeder. If you have more than 3 feeders, you will need to contact support@fr24.com to request an additional Feeder Key. Make sure to send them your account email-address, latitude, longitude, altitude, and if the key is for an ADSB or UAT feeder.

At the end of the sign-up process, you'll be presented with:

Congratulations! You are now registered and ready to share ADS-B data with Flightradar24.
+ Your sharing key (xxxxxxxxxxxx) has been configured and emailed to you for backup purposes.
+ Your radar id is X-XXXXXXX, please include it in all email communication with us.

Copy the sharing key you are given, and add the following line to your .env file:

  • Replace YOURSHARINGKEY with the sharing key from the output of the manual sign-up process.

For example:


UAT key and configuration (USA only, requires 2nd SDR and dump978 container already configured)

Get a separate sharing key for UAT as described here:

Copy the UAT sharing key you are given, and add the following line to your .env file:

  • Replace YOURSHARINGKEYUAT with the sharing key from the output of the sign-up process.

Deploying fr24 container

Open the docker-compose.yml file that was created when deploying ultrafeeder.

Append the following lines to the end of the file (inside the services: section):

    image: ghcr.io/sdr-enthusiasts/docker-flightradar24:latest
    tty: true
    container_name: fr24
    restart: unless-stopped
      - 8754:8754
      - BEASTHOST=ultrafeeder
      - FR24KEY=${FR24_SHARING_KEY}
      - /var/log

To explain what's going on in this addition:

  • We're creating a container called fr24, from the image ghcr.io/sdr-enthusiasts/docker-flightradar24:latest.

  • We're passing several environment variables to the container:

    • BEASTHOST=ultrafeeder to inform the feeder to get its ADSB data from the container ultrafeeder network.

    • FR24KEY will use the FR24_SHARING_KEY variable from your .env file.

  • We're using tmpfs for volumes that have regular I/O. Any files stored in a tmpfs mount are temporarily stored outside the container's writable layer. This helps to reduce:

    • The size of the container, by not writing changes to the underlying container; and

    • SD Card or SSD wear

Once the file has been updated, issue the command docker compose up -d in the application directory to apply the changes and bring up the fr24 container. You should see the following output:

 ✔ Container ultrafeeder  Running
 ✔ Container piaware      Running
 ✔ Container fr24         Started

We can view the logs for the environment with the command docker compose logs, or continually "tail" them with docker compose logs -f. At this stage, the logs will be fairly unexciting and look like this:

[s6-init] making user provided files available at /var/run/s6/etc...exited 0.
[s6-init] ensuring user provided files have correct perms...exited 0.

Once running, you can visit http://docker.host.ip.addr:8754 to access the fr24 web interface. You can also log onto FlightRadar24's website and click on the your profile button, and then "My data sharing" link to see your statistics.
