# sdr-enthusiasts/docker-adsb-ultrafeeder
`adsb-ultrafeeder` is a ADS-B data collector container that can be used to:
* retrieve ADS-B data from your SDR or other device
* display it on a local map, including options to show tracks, heatmaps, and system performance graphs
* forward the data to one or more aggregators using BEAST/BEAST-REDUCE/BEAST-REDUCE-PLUS format
* send MLAT data to these aggregators
* receive and consolidate MLAT results data (built-in `mlathub`)
* Interface with external visualization tools such as Grafana using statistics data available in InfluxDB and Prometheus format
In order to accomplish this, the container makes use of the following underlying technologies:
* SDR-Enthusiasts [Docker Base-Image](https://github.com/sdr-enthusiasts/docker-baseimage)
* [Wiedehopf's branch of `readsb`](https://github.com/wiedehopf/readsb)
* Wiedehopf's [tar1090](https://github.com/wiedehopf/tar1090) graphical interface
* Wiedehopf's [graphs1090](https://github.com/wiedehopf/graphs1090)
* [MLAT Client](https://github.com/adsbxchange/mlat-client.git)
It builds and runs on `linux/amd64`, `linux/arm/v7 (linux/armhf)` and `linux/arm64` architectures.
![ultrafeeder container architecture](https://user-images.githubusercontent.com/15090643/228925713-f2583af7-7cdf-4a8a-9ddb-d9e751991a46.png)
## Up-and-Running Quickly with `docker-compose`
* An example [`docker-compose.yml`](docker-compose.yml) file can be found in this repository.
* The accompanying environment variable values are defined in the [`.env`](.env) file in this repository
Once you have [installed Docker](https://github.com/sdr-enthusiasts/docker-install), you can follow these lines of code to get up and running in very little time:
```bash
sudo mkdir -p -m 777 /opt/adsb
cd /opt/adsb
wget https://raw.githubusercontent.com/sdr-enthusiasts/docker-adsb-ultrafeeder/main/docker-compose.yml
wget https://raw.githubusercontent.com/sdr-enthusiasts/docker-adsb-ultrafeeder/main/.env
```
Then edit the `docker-compose.yml` and `.env` files and make any changes as needed. Please configure ALL variables in `.env`:
```bash
nano docker-compose.yml
nano .env
```
Finally, bring up the stack. This may take a minute as it will automatically download the container and start it up:
```bash
docker compose up -d
```
## Ports
Some common ports are as follows (which may or may not be in use depending on your configuration). You can override the port mappings with the parameters shown in the [Optional Networking Parameters section](#optional-networking-parameters).
The general principle behind the port numbering, is:
* `30xxx` ports are connected to the main instance `readsb` that decodes and processes the SDR data
* `31xxx` ports are connected to the MLAT Hub
* `92xx` ports are for Prometheus statistics output
* `80` contains the Tar1090 web interface
| Port | Details |
|------|---------|
| `30001/tcp` | Raw protocol input |
| `30002/tcp` | Raw protocol output |
| `30003/tcp` | SBS/Basestation protocol output |
| `32006/tcp` | SBS/Basestation protocol input |
| `30004/tcp`<br/>`30104/tcp` | Beast protocol input |
| `30005/tcp` | Beast protocol output |
| `30006/tcp` | Beast reduce protocol output |
| `30047/tcp` | Json position output |
| `31003/tcp` | MLATHUB SBS/Basestation protocol output |
| `31004/tcp` | MLATHUB Beast protocol input |
| `31005/tcp` | MLATHUB Beast protocol output |
| `31006/tcp` | MLATHUB Beast-reduce protocol output |
| `9273/tcp` | Prometheus web interface with data from `readsb` |
| `9274/tcp` | Prometheus web interface with data from `Telegraf` |
| `80/tcp` | Tar1090 (map) web interface |
Any of these ports can be made available to the host system by using the `ports:` directive in your `docker-compose.yml`. The container's web interface is rendered to port `80` in the container. This can me mapped to a port on the host using the docker-compose `ports` directive. In the example [`docker-compose.yml`](docker-compose.yml) file, the container's Tar1090 interface is mapped to `8080` on the host system, and ports `9273-9274` are exposed as-is:
```yaml
ports:
- 8080:80 # to expose the web interface
- 9273-9274:9273-9274 # to expose the statistics interface to Prometheus
```
Json position output:
* outputs an aircraft object for every new position received for an aircraft if the --json-trace-interval has elapsed for that aircraft
* to make it output every received position, set READSB_JSON_TRACE_INTERVAL to 0.1
* each json object will be on a new line
* <https://github.com/wiedehopf/readsb/blob/dev/README-json.md>
Aircraft.json:
* <https://github.com/wiedehopf/readsb/blob/dev/README-json.md>
* available on the same port as the web interface, example: `http://192.168.x.yy:8087/data/aircraft.json`
## Runtime Environment Variables
The sections below describe how to configure each part of the container functionality. Each section describes what's needed to come up with a minimally viable configuration, followed by additional / optional parameters that can also be set.
### General Configuration
You need to make sure that the USB device can be accessed by the container. The best way to do so, is by adding the following to you `docker-compose.yml` file:
```yaml
device_cgroup_rules:
- 'c 189:* rwm'
...
volumes:
- /dev:/dev:ro
```
The advantage of doing this (over simply adding a `device:` directive pointing at the USB port) is that the construction above will automatically recover if you "hot plug" your dongle.
#### Basic Ultrafeeder Parameters
##### Mandatory Parameters
The following parameters must be set (mandatory) for the container to function:
| Environment Variable | Purpose | Default |

### Getting ADSB data to the Ultrafeeder
There are two ways to provide ADSB data to the Ultrafeeder:
* provide the container with access to a SDR or other hardware device that collects ADSB data
* allow the container to connect to a ADSB data source in Beast, Raw, or SBS format
These methods are not mutually exclusive - you can use both at the same time if you want.
#### Connecting to a SDR or other hardware device
If you want to connect your SDR to the container, here's how to do that:
##### Mandatory parameters
| Variable | Description | Controls which `readsb` option | Default |
|----------|-------------|--------------------------------|---------|
| `READSB_DEVICE_TYPE` | If using an SDR, set this to `rtlsdr`, `modesbeast`, `gnshulc` depending on the model of your SDR. If not using an SDR, leave un-set. | `--device-type=<type>` | Unset |
| `READSB_RTLSDR_DEVICE` | Select device by serial number. | `--device=<serial>` | Unset |
| `READSB_BEAST_SERIAL` | only when type `modesbeast` or `gnshulc` is used: Path to Beast serial device. | `--beast-serial=<path>` | `/dev/ttyUSB0` |
##### Optional/Additional Parameters
| Variable | Description | Controls which `readsb` option | Default |
|----------|-------------|--------------------------------|---------|
| `READSB_GAIN` | Set gain (in dB). Use `autogain` to have the container determine an appropriate gain, more on this below. | `--gain=<db>` | Max gain |
| `READSB_RTLSDR_PPM` | Set oscillator frequency correction in PPM. See [Estimating PPM](https://github.com/sdr-enthusiasts/docker-readsb-protobuf/README.MD#estimating-ppm) | `--ppm=<correction>` | Unset |
###### AutoGain for RTLSDR Devices
If you have set `READSB_GAIN=autogain`, then the system will take signal strength measurements to determine the optimal gain. The AutoGain functionality is based on a (slightly) modified version of [Wiedehopf's AutoGain](https://github.com/wiedehopf/autogain). AutoGain will only work with `rtlsdr` style receivers.
There are 2 distinct periods in which the container will attempt to figure out the gain:
* The initial period of 2 hours, in which an adjustment is done every 5 minutes
* The subsequent period, in which an adjustment is done once every day
Please note that in order for the initial period to complete, the container must run for 90 minutes without restarting.
When taking measurements, if the percentage of "strong signals" (i.e., ADSB messages with RSSI > 3 dB) is larger than 6%, AutoGain will reduce the receiver's gain by 1 setting. Similarly, if the percentage of strong signals is smaller than 2.5%, AutoGain will increment the receiver's gain by 1 setting. When AutoGain changes the gain value, the `readsb` component of the container will restart. This may show as a disconnect / reconnected in container logs.
We recommend running the initial period during times when there are a lot of planes overhead, so the system will get a good initial view of what signals look like when traffic is at its peak for your location. If you forgot to do this for any reason, feel free to give the AutoGain reset command (see below) during flights busy hour.
Although not recommended, you can change the measurement intervals and low/high cutoffs with these parameters:
| Environment Variable | Purpose | Default |
|----------------------|---------|---------|
| `READSB_AUTOGAIN_INITIAL_TIMEPERIOD` | How long the Initial Time Period should last (in seconds) | `7200` |
| `READSB_AUTOGAIN_INITIAL_INTERVAL` | The measurement interval to optimize gain during the initial period of 90 minutes (in seconds) | `300` |
| `READSB_AUTOGAIN_SUBSEQUENT_INTERVAL` | The measurement interval to optimize gain during the subsequent period (in seconds) | `86400` |
| `READSB_AUTOGAIN_LOW_PCT` | If the percentage of "strong signals" (stronger than 3dBFS RSSI) is below this number, gain will be increased | `2.5` |
| `READSB_AUTOGAIN_HIGH_PCT` | If the percentage of "strong signals" (stronger than 3dBFS RSSI) is above this number, gain will be decreased | `6.0` |
If you need to reset AutoGain and start over determining the gain, you can do so with this command:
```bash
docker exec -it ultrafeeder /usr/local/bin/autogain1090 reset
```
#### Connecting to external ADSB data sources
In addition to (or instead of) connecting to a SDR or hardware device to get ADSB data, the container also supports ingesting data from a TCP port. Here are some parameters that you need to configure if you want to make this happen:
##### Mandatory parameters
| Environment Variable | Purpose | Default |
|----------------------|---------|---------|
| `BEASTHOST` | IP/Hostname of a Mode-S/Beast provider (`dump1090`/`readsb`) | |
| `BEASTPORT` | TCP port number of Mode-S/Beast provider (`dump1090`/`readsb`) | `30005` |
| `MLATHOST` | Legacy parameter. IP/Hostname of an MLAT provider (`mlat-client`). Note - using this parameter will not make the MLAT data part of the consolidated mlathub. The preferred way of ingesting MLAT results is using the `mlathub` functionality of the container, see below for details | |
| `MLATPORT` | Legacy parameter used with `MLATHOST`. TCP port number of an MLAT provider (`mlat-client`) | 30105 |
###### Alternate Configuration Method with `READSB_NET_CONNECTOR`
Instead of (or in addition to) using `BEASTHOST`, you can also define ADSB data ingests using the `READSB_NET_CONNECTOR` parameter. This is the preferred way if you have multiple sources or destinations for your ADSB data. This variable allows you to configure incoming and outgoing connections. The variable takes a semicolon (`;`) separated list of `host,port,protocol[,uuid=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX]`, where:
* `host` is an IP address. Specify an IP/hostname/containername for incoming or outgoing connections.
* `port` is a TCP port number
* `protocol` can be one of the following:
* `beast_reduce_out`: Beast-format output with lower data throughput (saves bandwidth and CPU)
* `beast_reduce_plus_out`: Beast-format output with extra data (UUID). This is the preferred format when feeding the "new" aggregator services
* `beast_out`: Beast-format output
* `beast_in`: Beast-format input
* `raw_out`: Raw output
* `raw_in`: Raw input
* `sbs_out`: SBS-format output
* `vrs_out`: SBS-format output
* `uuid=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX` is an optional parameter that sets the UUID for this specific instance. It will override the global `UUID` parameter. This is only needed when you want to send different UUIDs to different aggregators.
NOTE: If you have a UAT dongle and use `dump978` to decode this, you should use `READSB_NET_CONNECTOR` to ingest UAT data from `dump978`. See example below
```yaml
environment:
...
- READSB_NET_CONNECTOR=dump978,37981,raw_in;another-data-aggregator.com,30005,beast_reduce_plus_out
...
```

### Web Gui (`tar1090`) Configuration
The Container creates an interactive web interface displaying the aircraft, based on Wiedehopf's widely used [tar1090](https://github.com/wiedehopf/tar1090) software.
The web interface is rendered to port `80` in the container. This can me mapped to a port on the host using the docker-compose `ports` directive.
All of the variables below are optional.
Note - due to design limitations of `readsb`, the `tar1090` graphical interface will by default ONLY show MLAT results from the aggregators/MLAT sources that were defined with the `MLAT_NET_CONNECTOR` parameter. If you want to show any additional MLAT results (for example, those from `piaware`), you should add a separate `READSB_NET_CONNECTOR` for them.

#### Enabling UAT data
ADS-B over UAT data is transmitted in the 978 MHz band, and this is used in the USA only. To display the corresponding graphs, you should:
1. Set the following environment parameters:
```yaml
- ENABLE_978=yes
- URL_978=http://dump978/skyaware978
```
2. Install the [`docker-dump978` container](https://github.com/sdr-enthusiasts/docker-dump978). Note - only containers downloaded/deployed on/after Feb 8, 2023 will work.
Note that you **must** configure `URL_978` to point at a working skyaware978 website with `aircraft.json` data feed. This means that the URL `http://dump978/skyaware978/data/aircraft.json` must return valid JSON data to this `tar1090` container.
#### Enabling AirSpy graphs
Users of AirSpy devices can enable extra `graphs1090` graphs by configuring the following:
* Set the following environment parameter:
```yaml
- ENABLE_AIRSPY=yes
```
* To provide the container access to the AirSpy statistics, map a volume in your `docker-compose.yml` file as follows:
```yaml
volumes:
- /run/airspy_adsb:/run/airspy_adsb
...
```
#### Enabling Disk IO and IOPS data
To allow the container access to the Disk IO data, you should map the following volume:
```yaml
volumes:
- /proc/diskstats:/proc/diskstats:ro
...
```
#### Configuring the Core Temperature graphs
By default, the system will use the temperature available at Thermal Zone 0. This generally works well on Raspberry Pi devices, and no additional changes are needed.
On different devices, the Core Temperature is mapped to a different Thermal Zone. To ensure the Core Temperature graph works, follow these steps
First check out which Thermal Zone contains the temperature you want to monitor. On your host system, do this:
```bash
for i in /sys/class/thermal/thermal_zone* ; do echo "$i - $(cat ${i}/type) - $(cat ${i}/temp 2>/dev/null)"; done
```
Something similar to this will be show:
```bash
/sys/class/thermal/thermal_zone0 - acpitz - 25000
/sys/class/thermal/thermal_zone1 - INT3400 Thermal - 20000
/sys/class/thermal/thermal_zone2 - TSKN - 43050
/sys/class/thermal/thermal_zone3 - NGFF - 32050
/sys/class/thermal/thermal_zone4 - TMEM - 39050
/sys/class/thermal/thermal_zone5 - pch_skylake - 40500
/sys/class/thermal/thermal_zone6 - B0D4 - 54050
/sys/class/thermal/thermal_zone7 - iwlwifi_1 -
/sys/class/thermal/thermal_zone8 - x86_pkg_temp - 57000
```
Repeat this a few times to ensure that the temperature varies and isn't hardcoded to a value. In our case, either Thermal Zone 5 (`pch_skylake` is the Intel Core name) or Thermal Zone 8 (the temp of the entire SOC package) can be used. Once you have determined which Thermal Zone number you want to use, map it to a volume like this. Make sure that the part to the left of the first `:` reflects your Thermal Zone directory; the part to the right of the first `:` should always be `/sys/class/thermal/thermal_zone0:ro`.
Note that you will have to add `- privileged: true` capabilities to the container. This is less than ideal as it will give the container access to all of your system devices and processes. Make sure you feel comfortable with this before you do this.
```yaml
privileged: true
volumes:
- /sys/class/thermal/thermal_zone8:/sys/class/thermal/thermal_zone0:ro
...
```
Note - on some systems (DietPi comes to mind), `/sys/class/thermal/` may not be available.
### `timelapse1090` Configuration
Legacy: **We recommend AGAINST enabling this feature** as it has been replaced with <http://dockerhost:port/?replay>. `timelapse1090` writes a lot of data to disk, which could shorten the lifespan of your Raspiberry Pi SD card. The replacement functionality is better and doesn't cause any additional disk writes.
| Environment Variable | Purpose | Default |
|----------------------|---------|---------|
| `ENABLE_TIMELAPSE1090` | Optional / Legacy. Set to any value to enable timelapse1090. Once enabled, can be accessed via <http://dockerhost:port/timelapse/> | Unset |
| `TIMELAPSE1090_INTERVAL` | Snapshot interval in seconds | `10` |
| `TIMELAPSE1090_HISTORY` | Time saved in hours | `24` |
## Web Pages
If you have configured the container as described above, you should be able to browse to the following web pages:
You should now be able to browse to:
* <http://dockerhost/> to access the tar1090 web interface.
* <http://dockerhost/?replay> to see a replay of past data
* <http://dockerhost/?heatmap> to see the heatmap for the past 24 hours
* <http://dockerhost/?heatmap&realHeat> to see a different heatmap for the past 24 hours
* <http://dockerhost/?pTracks> to see the tracks of all planes for the past 24 hours
* <http://dockerhost/graphs1090/> to see performance graphs
## Paths
No paths need to be mapped through to persistent storage. However, if you don't want to lose your range outline and aircraft tracks/history and heatmap / replay data on container restart, you can optionally map these paths:
| Path | Purpose |
|------|---------|
| `/opt/adsb/ultrafeeder/globe_history:/var/globe_history` | Holds range outline data, heatmap / replay data and traces if enabled.
*Note: this data won't be automatically deleted, you will need to delete it eventually if you map this path.* |
| `/opt/adsb/ultrafeeder/timelapse1090:/var/timelapse1090` | Holds timelapse1090 data if enabled. (We recommend against enabling this feature, see above) |
| `/opt/adsb/ultrafeeder/collectd:/var/lib/collectd` | Holds graphs1090 & performance data |
| `/proc/diskstats:/proc/diskstats:ro` | Makes disk statistics available to `graphs1090` |
| `/sys/class/thermal/thermal_zone8:/sys/class/thermal/thermal_zone0:ro` | Only needed on some systems to display the CPU temperature in `graphs1090`, see [here](#configuring-the-core-temperature-graphs) |
### Configuring the built-in MLAT Hub
An "MLAT Hub" is an aggregator of MLAT results from several sources. Since the container is capable of sending MLAT data to multiple ADSB aggregators (like adsb.lol/fi/one, etc), we built in a capability to:
* collect the MLAT results from all of these services
* ingest MLAT results from other containers (FlightAware, Radarbox, etc.)
* make the consolidated MLAT results available on a port in Beast or SBS (BaseStation) format
* create outbound connections using any supported format to send your Beast data wherever you want
Note - due to design limitations of `readsb`, the `tar1090` graphical interface will by default ONLY show MLAT results from the aggregators/MLAT sources that were defined with the `MLAT_NET_CONNECTOR` parameter. If you want to show any additional MLAT results (for example, those from `piaware`), you should add a separate `READSB_NET_CONNECTOR` for them. Adding these sources only to `MLATHUB_NET_CONNECTOR` will make the data available on the MLATHUB, but won't display them on your `tar1090` map.
Generally, there is little to configure, but there are a few parameters that you can set or change:
| Variable | Description | Default if omitted|
|----------|-------------|--------------------------------|
| `MLATHUB_SBS_OUT_PORT` | TCP port where the consolidated MLAT results will be available in SBS (BaseStation) format | `31003` |
| `MLATHUB_BEAST_IN_PORT` | TCP port you where you can send additional MLAT results to, in Beast format | `31004` |
| `MLATHUB_BEAST_OUT_PORT` | TCP port where consolidated MLAT results will be available in Beast format | `31005` |
| `MLATHUB_BEAST_REDUCE_OUT_PORT` | TCP port where consolidated MLAT results will be available in Beast format with reduced data rates | `31006` |
| `MLATHUB_NET_CONNECTOR` | List of semi-colon (`;`) separated IP or host, port, and protocols where MLATHUB will connect to ingest or send MLAT data. It follows the same syntax as described in the [`READSB_NET_CONNECTOR` syntax section](#alternate-configuration-method-with-readsb_net_connector) above. | Unset |
## Metrics
This image contains [Telegraf](https://docs.influxdata.com/telegraf/), which will be used to capture metrics from `readsb` if an output is enabled.
### Output to InfluxDBv2
In order for Telegraf to output metrics to an [InfluxDBv2](https://docs.influxdata.com/influxdb/) time-series database, the following environment variables can be used:
| Variable | Description |
| ---- | ---- |
| `INFLUXDBV2_URL` | The URL of the InfluxDB instance |
| `INFLUXDBV2_TOKEN` | The token for authentication |
| `INFLUXDBV2_BUCKET` | Destination bucket to write into |
### Output to Prometheus
In order for Telegraf to serve a [Prometheus](https://prometheus.io) endpoint, the following environment variables can be used:
| Variable | Description |
| ---- | ---- |
| `PROMETHEUS_ENABLE` | Set to `true` for a Prometheus endpoint on `http://0.0.0.0:9273/metrics` |
## Message decoding introspection
You can look at individual messages and what information they contain, either for all or for an individual aircraft by hex:
```shell
# only for hex 3D3ED0
docker exec -it ultrafeeder /usr/local/bin/viewadsb --show-only 3D3ED0
# for all aircraft
docker exec -it ultrafeeder /usr/local/bin/viewadsb --no-interactive
# show position / CPR debugging for hex 3D3ED0
docker exec -it ultrafeeder /usr/local/bin/viewadsb --cpr-focus 3D3ED0
```
## Logging
All logs are to the container's stdout and can be viewed with `docker logs -t [-f] container`.
