# dgpsip(1)

get Differential GPS corrections via the internet

## NAME

**dgpsip** – get Differential GPS corrections via the internet

## SYNOPSIS

**dgpsip** \[**-d**\] \[**-t**\] \[**-4**\] \[**-6**\] \[**-B**\] \[**-v** *verbosity*\] \[**-h** *host*\] \[**-p** *port*\] \[**-o** *tty*\] \[**-s** *baudrate*\] \[**-n** *nmea\_tty*\] \[**-N** *nmea\_baudrate*\] \[**-c** *logfile*\]

## DESCRIPTION

- **-h**

  host\_name or ip\_address to connect to

  ```
  default dgps.wsrcc.com
  ```

- **-p**

  port\_name or port\_number to connect to on remote machine.

  ```
  default number: 2101
  ```

  ```
  default name: rtcm-sc104
  ```

- **-o**

  output\_tty

  ```
  default: /dev/gps
  ```

- **-s**

  tty\_baudrate

  ```
  default: 4800
  ```

- **-n**

  nmea\_tty

  ```
  default: use output_tty
  ```

  If set, use this tty for NMEA input and use output\_tty for RTCM output.  This option is needed by some oem GPS units with two tty connections.

- **-N**

  nmea\_baudrate

  ```
  default: 4800
  ```

  Not used unless nmea\_tty specified.

- **-c**

  nmea\_logfile

  ```
  default: no_logfile
  ```

  Write an nmea logfile with the specified name.

- **-v**

  verbosity\_level

  ```
  default: 0
  ```

  ```
  Verbosity = 1 prints version number.
  ```

  ```
  Verbosity = 2 prints a periodic accuracy and position report
  ```

  ```
  Verbosity = 3 prints a per packet dot
  ```

  ```
  Verbosity = 5 prints connection error msg.
  ```

  ```
  Verbosity = 10 prints per-packet byte counts.
  ```

  ```
  Verbosity = 11 prints nmea parser output.
  ```

- **-d**

  Decode rtcm stream and turn off tty output by default.  To run both decoder and tty output:

  ```
  dgpsip -d -o /dev/gps
  ```

- **-4**

  force an ipv4 connection

- **-6**

  force an ipv6 connection

- **-t**

  turn on SV track recording / picture mode.

- **-B**

  turn off binary mode for the above picture mode.

## EXAMPLES

```
dgpsip -d
```

If dgpsip can't connect to the server it sleeps and tries again a short time later.  dgpsip uses an exponential back off so as to not overload a rebooting server.

## BUGS

None reported yet.
