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. \.TP \fBgnss\-sdr\fR 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. .SH OPTIONS \fBgnss\-sdr\fR takes the following options: .TP \fB\-config_file=\fR\fI<path\-to\-configuration\-file>\fR Set the configuration file. .TP \fB\-signal_source=\fR\fI<path\-to\-raw\-signal\-file>\fR If defined, path to the file containing the signal samples (overrides the data file specified in the configuration file). .TP \fB\-log_dir=\fR\fI<path\-to\-directory>\fR If defined, overrides the default directory where logs are saved. .TP \fB\-doppler_max=\fR\fIdoppler\fR If defined, maximum Doppler value in the search grid, in Hz (overrides the configuration file), .TP \fB\-cn0_samples=\fR\fIsamples\fR Number of correlator outputs used for CN0 estimation. .TP \fB\-cn0_min=\fR\fIcn0_min\fR Minimum valid CN0 (in dB-Hz). .TP \fB\-max_lock_fail=\fR\fImax_lock_fail\fR Number number of lock failures before dropping satellite. .TP \fB\-carrier_lock_th=\fR\fIcarrier_lock_th\fR Carrier lock threshold (in rad). .TP \fB\-dll_bw_hz=\fR\fIdll_bw_hz\fR If defined, bandwidth of the DLL low pass filter, in Hz (overrides the configuration file). .TP \fB\-pll_bw_hz=\fR\fIpll_bw_hz\fR If defined, bandwidth of the PLL low pass filter, in Hz (overrides the configuration file). .TP \fB\-RINEX_version=\fI<version>\fR Specifies the RINEX version (2.11 or 3.02). Default: "3.02". .TP \fB\-version\fR Print program version and exit. .TP \fB\-help\fR Print all the available commandline flags and exit. .SH SEE ALSO .BR volk_gnsssdr_profile (1) \.TP Examples of configuration files available at: ${prefix}/share/gnss\-sdr/conf, where ${prefix} uses to be /usr or /usr/local. \.TP Check http://gnss\-sdr.org for more information. .SH BUGS Please report bugs at https://github.com/gnss-sdr/gnss-sdr/issues .SH AUTHOR Carles Fernandez\-Prades (carles.fernandez@cttc.es) \.TP This software package has been developed at CTTC (Centre Tecnologic de Telecomunicacions de Catalunya, http://www.cttc.es) with contributions from around the world.
