DGPSIP(1)              DragonFly General Commands Manual             DGPSIP(1)


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.
