globe.decentrafly.com / feed

The decentrafly.com feed client is a toolkit that allows you to install, run and maintain a ADS-B / UAT / MLAT / ACARS / VDL2 feed client.

By default, it feeds MLAT+ADSB to feed.decentrafly.com. You can enable UAT/ACARS/VDL2, and feed to your plane data to FlightRadar24, Radarbox, Piaware, and more

It is designed to be run on a Raspberry Pi, but can be run on any Linux Debian-like system.

With a few commands, you can easily feed to other community aggregators.

ADSBExchange-style feeder

If you are looking for a script similar to the ADSBExchange feeder to run on your existing station, you can see here.

Or run:

curl -fsL -o /tmp/decentrafly.sh https://raw.githubusercontent.com/decentrafly/feed/masterx/setup.sh && sudo bash /tmp/decentrafly.sh

Quick Start

Run this as root on a fresh install of Raspberry Pi OS Lite or similar.

This script gets all the requirements for your system.

For your own security, Please consider analysing the decentrafly-init script which you are about to run on your system.

curl -Ls https://raw.githubusercontent.com/decentrafly/feed/main/bin/decentrafly-init | bash
cd /opt/decentrafly/
cp .env.example .env

Then, set the environment variables.

You can either edit the .env file, or run decentrafly-env set <key> <value>

# Altitude in meters
decentrafly-env set FEEDER_ALT_M 542
# Latitude
decentrafly-env set FEEDER_LAT 98.76543
# Longitude
decentrafly-env set FEEDER_LONG 12.34567
# Timezone (see https://en.wikipedia.org/wiki/List_of_tz_database_time_zones)
decentrafly-env set FEEDER_TZ America/New_York
# SDR Serial Number
decentrafly-env set ADSB_DONGLE_SERIAL 1090
# Site name (shows up on the MLAT map!)
decentrafly-env set MLAT_SITE_NAME "My epic site"
# Would you like to appear on globe.decentrafly.com? Then set this:
decentrafly-env unset DECENTRAFLY_MLAT_CONFIG

These are the minimum environment variables you need to set.

Then, run:

decentrafly-debug && decentrafly-up

Let's check if everything is working:

• http://IP:8080 (readsb)
• http://IP:8082 (decentrafly)
• https://globe.decentrafly.com (ADSB)
• https://globe.decentrafly.com (MLAT)

Usage

By default, the client will feed to adsb.lol.

To see the current list of supported aggregators, see the services.txt file.

The decentrafly service supports feeding to multiple aggregators.

If you have an issue with the feed client, please paste.ee your error logs join our chat on discord.

Restart the stack

decentrafly-up

Enabling a service

To enable a service, run decentrafly-service enable <service> To disable a service, run decentrafly-service disable <service> This is a helper command that will edit the services.txt file, and run decentrafly-gen to generate a new cmdline.txt.

You may have to define further environment variables in the .env file.

Then, run decentrafly-gen to generate a new cmdline.txt.

The cmdline.txt is used by the decentrafly binaries to know what services to start.

Once you have done this, run decentrafly-up to start the containers.

Troubleshooting

To update, run decentrafly-update

Running decentrafly-debug will tell you about common mistakes.

I cannot find myself on the MLAT Map

decentrafly.com enables the --privacy flag for your MLAT client by default. This hides you from the MLAT map.

Do you want to appear on the map? Then run:

decentrafly-env unset DECENTRAFLY_MLAT_CONFIG && decentrafly-up

Thank you SDR-Enthusiasts!

This would not be possible without SDR-Enthusiasts who have made the original docker-compose file.

This repo is largely based off of their work plus some command line interface tools to make running the stack a bit simpler.

Their documentation can be very useful in enabling extra feeders..

Feeding directly to other aggregators

The decentrafly service can feed to other aggregators.

In this example, we also feed ADSB.lol.

This is not an endorsement and decentrafly is not affiliated with adsb.lol.

Run

NOTE: This is using --privacy, which excludes you from adsb.lol map, and should exclude you from other aggregators maps too.

decentrafly-env set DECENTRAFLY_ADDITIONAL_NET_CONNECTOR "feed.decentrafly.com,30004,beast_reduce_out;feed.adsb.lol,30004,beast_reduce_out"
decentrafly-env set DECENTRAFLY_ADDITIONAL_MLAT_CONFIG "feed.decentrafly.com,31090,39001,--privacy;feed.adsb.lol,31090,39002,--privacy"
decentrafly-env set MLATHUB_NET_CONNECTOR "decentrafly,39000,beast_in;decentrafly,39001,beast_in;decentrafly,39002,beast_in"

If you would like to disable privacy mode, instead, use:

decentrafly-env set DECENTRAFLY_ADDITIONAL_NET_CONNECTOR "feed.decentrafly.com,30004,beast_reduce_out;feed.adsb.lol,30004,beast_reduce_out"
decentrafly-env set DECENTRAFLY_ADDITIONAL_MLAT_CONFIG "feed.decentrafly.com,31090,39001;feed.adsb.lol,31090,39002"
decentrafly-env set MLATHUB_NET_CONNECTOR "decentrafly,39000,beast_in;decentrafly,39001,beast_in;decentrafly,39002,beast_in"
