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:
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 above, the container's website is made available at port 8078 on the host system.
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.
| `ENABLE_TIMELAPSE1090` | Optional / Legacy. Set to any value to enable timelapse1090. Once enabled, can be accessed via <http://dockerhost:port/timelapse/>. | Unset |
| `READSB_EXTRA_ARGS` | Optional, allows to specify extra parameters for readsb | Unset |
| `READSB_DEBUG` | Optional, used to set debug mode. `n`: network, `P`: CPR, `S`: speed check | Unset |
| `S6_SERVICES_GRACETIME` | Optional, set to 30000 when saving traces / globe_history | `3000` |
| `READSB_MAX_RANGE` | Optional. Maximum range (in nautical miles). | `300` |
| `READSB_ENABLE_BIASTEE` | Set to any value to enable bias tee on supporting interfaces | | Unset |
| `READSB_RX_LOCATION_ACCURACY` | Accuracy of receiver location in metadata: 0=no location, 1=approximate, 2=exact | `--rx-location-accuracy=<n>` | `2` |
| `READSB_HEATMAP_INTERVAL` | Per plane interval for heatmap and replay (if you want to lower this, also lower json-trace-interval to this or a lower value) | `--heatmap=<sec>` | `15` |
| `READSB_MAX_RANGE` | Absolute maximum range for position decoding (in nm) | `--max-range=<dist>` | `300` |
| `READSB_STATS_EVERY` | Number of seconds between showing and resetting stats. | `--stats-every=<sec>` | Unset |
| `READSB_STATS_RANGE` | Set this to any value to collect range statistics for polar plot. | `--stats-range` | Unset |

| `READSB_EXTRA_ARGS` | Optional, allows to specify extra parameters for readsb | | Unset |
| `S6_SERVICES_GRACETIME` | Optional, set to 30000 when saving traces / globe_history | | `3000` |
`READSB_EXTRA_ARGS` just passes arguments to the commandline, you can check this file for more options for wiedehofp's readsb fork: <https://github.com/wiedehopf/readsb/blob/dev/help.h>
### 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:
| `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` |
| `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 |
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:
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.
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:
*`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
There are many optional parameters relating to the ingestion of data and the general networking functioning of the `readsb` program that implements this functionality.
| `READSB_NET_BEAST_REDUCE_INTERVAL` | BeastReduce position update interval, longer means less data (valid range: `0.000` - `14.999`) | `--net-beast-reduce-interval=<seconds>` | `0.125` |
| `READSB_NET_BEAST_REDUCE_FILTER_DIST` | Restrict beast-reduce output to aircraft in a radius of X nmi | `--net-beast-reduce-filter-dist=<nmi>` | Unset |
| `READSB_NET_BEAST_REDUCE_FILTER_ALT` | Restrict beast-reduce output to aircraft below X ft | `--net-beast-reduce-filter-alt=<ft>` | Unset |
| `READSB_WRITE_STATE_ONLY_ON_EXIT` | if set to anything, it will only write the status range outlines, etc. upon termination of `readsb` | `--write-state-only-on-exit` | Unset |
| `READSB_JSON_INTERVAL` | Update interval for the webinterface in seconds / interval between aircraft.json writes | `--write-json-every=<sec>` | `1.0` |
| `READSB_JSON_TRACE_INTERVAL` | Per plane interval for json position output and trace interval for globe history | `--json-trace-interval=<sec>` | `15` |
The Container creates an interactive web interface displaying the aircraft, based on Wiedehopf's widely used [tar1090](https://github.com/wiedehopf/tar1090) software.
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.
| `URL_978` | The URL needs to point at where you would normally find the skyview978 webinterface, for example `http://192.168.0.29/skyaware978`. Note -- do not use `localhost` or `127.0.0.1 | |
| `TAR1090_ENABLE_AC_DB` | Set to `true` to enable extra information, such as aircraft type and registration, to be included in in `aircraft.json` output. Will use more memory; use caution on older Pis or similar devices. | `false` |
| `HEYWHATSTHAT_PANORAMA_ID` | Your `heywhatsthat.com` panorama ID. See <https://github.com/wiedehopf/tar1090#heywhatsthatcom-range-outline> | |
| `HEYWHATSTHAT_ALTS` | Comma separated altitudes for multiple outlines. Use no units or `ft` for feet, `m` for meters, or `km` for kilometers. Only integer numbers are accepted, no decimals please | `12192m` (=40000 ft) |
| `HTTP_ACCESS_LOG` | Optional. Set to `true` to display HTTP server access logs. | `false` |
| `HTTP_ERROR_LOG` | Optional. Set to `false` to hide HTTP server error logs. | `true` |
* For documentation on the aircraft.json format see this page: <https://github.com/wiedehopf/readsb/blob/dev/README-json.md>
* TAR1090_ENABLE_AC_DB causes readsb to load the tar1090 database as a csv file from this repository: <https://github.com/wiedehopf/tar1090-db/tree/csv>

#### `tar1090` `config.js` Configuration - Range Rings
| Environment Variable | Purpose | Default |
|----------------------|---------|---------|
| `TAR1090_RANGERINGS` | `false` to hide range rings | `true` |
| `TAR1090_RANGERINGSDISTANCES` | Distances to display range rings, in miles, nautical miles, or km (depending settings value '`TAR1090_DISPLAYUNITS`'). Accepts a comma separated list of numbers (no spaces, no quotes). | `100,150,200,250` |

| `ENABLE_AIRSPY` | Optional, set to any non-empty value if you want to enable the special AirSpy graphs. See below for additional configuration requirements | Unset |
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.
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
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.
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.
| `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` |
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:
| `/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) |
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:
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.
| `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 |
| `MLATHUB_ENABLE_ADSB_INGEST` | If set to any non-empty value, the MLATHUB will ingest the ADSB data from the readsb component and make it available on its output port. This is useful if you want to connect to external applications that want both ADSB and MLAT result data (for example, Planefence). Note -- do not use this option to feed external aggregators as they generally do not want to receive processed MLAT data. | Unset |
