NAME

       UGsmooth - send UGear-formatted GPS data to a FlightGear instance

SYNOPSIS

       UGsmooth --help
           | --infile infile_name [options]...
           | --flight flight_dir [options]...
           | --serial dev_name --outfile outfile_name [options]...

DESCRIPTION

       UGsmooth is a utility that reads GPS data in UGear format from a text file, a directory containing flight
       data or from a device connected to the serial port, parses it and sends it to a FlightGear  instance  for
       replaying.

OPTIONS

       --help Display usage information and exit.

       --infile infile_name
              Read GPS data from infile_name.

       --flight flight_dir
              Read GPS data from the flight directory named flight_dir.

       --serial dev_name
              Read GPS data from the serial device named dev_name.

       --outfile outfile_name
              Save the data retrieved from the device to outfile_name.

       --hertz frequency
              Specify  the frequency to use for sending data to the FlightGear instance.  By default, events are
              sent at a frequency of 60 Hz.

       --host hostname
              Send the data to the FlightGear instance running on hostname.

              If --host is not specified, the default is to send the data to localhost.

       --broadcast
              Send flight data model and control data as broadcast packets.

       --opengc-port port
              Set the port OpenGC data should be sent to. By default, data is sent to port 6000.

       --fdm-port port
              Set the port flight data model data should be sent to. By default, data is sent to port 5505.

       --ctrls-port port
              Set the port control data should be sent to. By default, data is sent to port 5506.

       --groundtrack-heading
              Calculate the aircraft heading from the GPS velocity instead of using the raw heading recorded  by
              the device.

       --ground-speed
              Calculate  the  ground  speed from the GPS velocity instead of using the raw speed recorded by the
              device.

       --estimate-control-deflections
              Estimate control deflections from the angular velocities instead  of  using  the  raw  deflections
              recorded by the device.

       --altitude-offset meters
              Add the specified offset (in meters) to the altitude sent to FlightGear.

       --skip-seconds seconds
              Do not transmit the first seconds seconds of data.

              This option is ignored when reading GPS data from a serial device.

       --no-real-time
              Do not update the elapsed time.

       --ignore-checksum
              Do not discard data with invalid checksums.

              This option is ignored when reading GPS data from a flight directory.

       --sg-swap
              Activate the special double swap logic for the (non-standard) stargate double format.

EXIT STATUS

       UGsmooth  exits  with  0  on  success, with -1 if the syntax of the command-line arguments is wrong or an
       error occurs.
