Feeding ADSBHub

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

The main goal of ADSBHub is to become a ADS-B data sharing centre and valuable data source for all enthusiasts and professionals interested in development of ADS-B related software.

The docker image ghcr.io/sdr-enthusiasts/docker-adsbhub contains the required feeder software and all required prerequisites and libraries. This needs to run in conjunction with ultrafeeder (or another Beast provider).

Getting a Station Key

Obtaining an ADSBHub Station Key

First-time users should obtain a ADSBHub Station dynamic IP key. Follow the directions for steps 1 and 2 at ADSBHub how to feed, ensuring your station is set up as a client and the data protocol set as "SBS" (see below.)

Existing users should sign in to their ADSBHub account, go to their "Settings" page, click on their station (in the bar at the top of the settings table) and retrieve their station key.

Setting up Your Station

In your station preferences, you should set the following:

• Feeder type: Linux

• Data Protocol: SBS

• Station mode: Client

Update .env file with ADSBHub Station Key

Inside your application directory (/opt/adsb), edit the .env file using your favourite text editor. Beginners may find the editor nano easy to use:

nano /opt/adsb/.env

This file holds all of the commonly used variables (such as our latitude, longitude and altitude). We're going to add our ADSBHub Station Key to this file. Add the following line to the file:

ADSBHUB_STATION_KEY='YOURSTATIONKEY'

• Replace YOURSTATIONKEY with the station key you retrieved earlier.

• The single quotes (') are important, as the station key from ADSBHub contains special characters that would confuse docker compose if the single quotes were missing.

For example:

ADSBHUB_STATION_KEY='vrMr@AZn660X0H^0Usn~rcj$UJA7VlR.vEu4c;uh7mfU-J9ZUBXpJiUuWj37DTa5BtL'

Deploying feeder 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):

  adsbhub:
    image: ghcr.io/sdr-enthusiasts/docker-adsbhub:latest
    container_name: adsbhub
    restart: unless-stopped
    environment:
      - TZ=${FEEDER_TZ}
      - SBSHOST=ultrafeeder
      - CLIENTKEY=${ADSBHUB_STATION_KEY}

To explain what's going on in this addition:

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

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

  • SBSHOST=ultrafeeder to inform the feeder to get its ADSB data from the container ultrafeeder

  • TZ will use the FEEDER_TZ variable from your .env file.

  • CLIENTKEY will use the ADSBHUB_STATION_KEY variable from your .env file.

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 adsbhub container. You should see the following output:

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

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

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