## 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
* feed them back to the built-in `tar1090` graphical interface
* 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
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 | `31004` |
| `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_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 above. | Unset |
## 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 tar1090 /usr/local/bin/viewadsb --show-only 3D3ED0
docker exec -it adsb-superfeeder /usr/local/bin/viewadsb --show-only 3D3ED0
# for all aircraft
docker exec -it tar1090 /usr/local/bin/viewadsb --no-interactive
docker exec -it adsb-superfeeder /usr/local/bin/viewadsb --no-interactive
# show position / CPR debugging for hex 3D3ED0
docker exec -it tar1090 /usr/local/bin/viewadsb --cpr-focus 3D3ED0
docker exec -it adsb-superfeeder /usr/local/bin/viewadsb --cpr-focus 3D3ED0
```
