**Note for Ubuntu 14.04 LTS "trusty" users:** you will need to build from source and install GNU Radio manually, as explained below, since GNSS-SDR requires `gnuradio-dev` >= 3.7.3, and Ubuntu 14.04 came with 3.7.2. Install all the packages above BUT EXCEPT `libuhd-dev`, `gnuradio-dev` and `gr-osmosdr` (and remove them if they are already installed in your machine), and install those dependencies using PyBOMBS. The same applies to `libmatio-dev`: Ubuntu 14.04 came with 1.5.2 and the minimum required version is 1.5.3. Please do not install the `libmatio-dev` package and install `libtool`, `automake` and `libhdf5-dev` instead. A recent version of the library will be downloaded and built automatically if CMake does not find it installed.

.SH NAME
\fBgnss\-sdr\fR \- GNSS Software Defined Receiver.
.SH SYNOPSIS
\fBgnss\-sdr \-config_file=\fR\fI<path\-to\-configuration\-file>\fR [OPTION]...
\fBgnss\-sdr \-c=\fR\fI<path\-to\-configuration\-file>\fR [OPTION]...
.SH DESCRIPTION
\fBgnss\-sdr\fR 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.
\.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.
\.TP
There is some flexibility in how flags may be specified. The following examples are equivalent:
\.RS 8
\.TP
gnss\-sdr \-c=/home/user/rx.conf
\.TP
gnss\-sdr \-\-c=/home/user/rx.conf

Number of lock failures before dropping satellite. It defaults to 50 failures.
.TP
\fB\-carrier_lock_th=\fR\fI<carrier_lock_th>\fR
Carrier lock error threshold (in rad). It defaults to 0.85 rad (48.7 degrees).
.TP
\fB\-dll_bw_hz=\fR\fI<dll_bw_hz>\fR
If defined, bandwidth of the DLL low pass filter, in Hz (overrides the configuration file).
.TP
