NAME

       gnss-sdr - GNSS Software Defined Receiver.

SYNOPSIS

       gnss-sdr -c=<path-to-configuration-file> [OPTION]...

DESCRIPTION

       gnss-sdr  is  a  Global  Navigation Satellite Systems Software Defined Receiver written in
       C++. It implements all the signal processing chain, taking as  input  raw  samples  coming
       from  the  output  of  an  Analog-to-Digital  Converter,  and  processing  them  up to the
       computation of the Position-Velocity-Time solution, including the generation of  code  and
       phase measurements.

       gnss-sdr  is  able to work with raw data files or, if there is computational power enough,
       in real time with suitable radio frequency front-ends. The whole receiver is defined in  a
       single configuration file, and therefore users can define theirs.

       There  is  some  flexibility  in  how  flags  may be specified. The following examples are
       equivalent:

               gnss-sdr -c=/home/user/rx.conf

               gnss-sdr --c=/home/user/rx.conf

               gnss-sdr -c /home/user/rx.conf

               gnss-sdr --c /home/user/rx.conf

OPTIONS

       gnss-sdr takes the following options:

       -c=<path-to-configuration-file> or -config_file=<path-to-configuration-file>
              Set the configuration file. This flag is mandatory.

       -s=<path-to-raw-signal-file> or -signal_source=<path-to-raw-signal-file>
              If defined, path to the file containing the signal samples (overrides the data file
              specified in the configuration file).

       -log_dir=<path-to-directory>
              If defined, overrides the default directory where logs are saved.

       -doppler_max=<doppler_max>
              If  defined,  maximum  Doppler  value  in  the  search  grid,  in Hz (overrides the
              configuration file).

       -doppler_step=<doppler_step>
              If defined, sets the frequency step in  the  search  grid,  in  Hz  (overrides  the
              configuration file).

       -cn0_samples=<samples>
              Number  of  correlators outputs (one per integration time) used for CN0 estimation.
              It defaults to 20 outputs.

       -cn0_min=<cn0_min>
              Minimum valid CN0 (in dB-Hz). It defaults to 25 dB-Hz. If  set,  it  overrides  the
              configuration file.

       -max_lock_fail=<max_lock_fail>
              Maximum  number  of  lock  failures  before dropping a satellite. It defaults to 50
              failures. If set, it overrides the configuration file.

       -carrier_lock_th=<carrier_lock_th>
              Carrier lock error threshold (in rad). It defaults to 0.85 rad (48.7  degrees).  If
              set, it overrides the configuration file.

       -dll_bw_hz=<dll_bw_hz>
              If   defined,  bandwidth  of  the  DLL  low  pass  filter,  in  Hz  (overrides  the
              configuration file).

       -pll_bw_hz=<pll_bw_hz>
              If  defined,  bandwidth  of  the  PLL  low  pass  filter,  in  Hz  (overrides   the
              configuration file).

       -RINEX_version=<version>
              If  defined, specifies the RINEX version (2.11 or 3.02). Default: "3.02". Overrides
              the configuration file.

       -version
              Print program version and exit.

       -help  Print all the available commandline flags and exit.
