The `gpsd` component is using the GPS information collected by [gpsd](http://catb.org/gpsd/) and a GPS receiver.

A requirement is that `gpsd` is installed (`$ sudo apt-get install gpsd` or `$ sudo dnf -y install gpsd`). `gpsd` uses the socket activation feature of systemd on recent Linux distributions for USB receivers. This means that if you plug your GPS receiver in, `gpsd` is started. Other GPS device may work too, but this was not tested.

```bash
$ sudo systemctl status gpsdctl@ttyUSB0.service 
● gpsdctl@ttyUSB0.service - Manage ttyUSB0 for GPS daemon
   Loaded: loaded (/usr/lib/systemd/system/gpsdctl@.service; static; vendor preset: disabled)

  Process: 5303 ExecStart=/bin/sh -c [ "$USBAUTO" = true ] && /usr/sbin/gpsdctl add /dev/%I || : (code=exited, status=0/SUCCESS)
 Main PID: 5303 (code=exited, status=0/SUCCESS)

```

To check if your setup is working, connect to port 2947 on the host where `gpsd` is running with `telnet`. This may need adjustments to your firewall.

```bash
$ telnet localhost 2947
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
{"class":"VERSION","release":"3.15","rev":"3.15-2.fc23","proto_major":3,"proto_minor":11}
```

To setup a GPSD sensor in your installation, add the following to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
sensor:
  - platform: gpsd
```

Configuration variables:

- **host** (*Optional*): The host where GPSD is running. Defaults to `localhost`.
- **port** (*Optional*): The port which GPSD is using. Defaults to `2947`. 
- **name** (*Optional*): Friendly name to use for the frontend. Default to GPS.
