### Alternative 2: Install dependencies using PyBOMBS
This option is adequate if you are interested in development, in working with the most recent versions of software dependencies, want more fine tuning on the installed versions, or simply in building everything from the scratch just for the fun of it. In such cases, we recommend to use [PyBOMBS](http://gnuradio.org/pybombs "Python Build Overlay Managed Bundle System wiki") (Python Build Overlay Managed Bundle System), GNU Radio's meta-package manager tool that installs software from source, or whatever the local package manager is, that automatically does all the work for you. Please take a look at the configuration options and general PyBOMBS usage at https://github.com/gnuradio/pybombs. Here we provide a quick step-by-step tutorial.

1. After building the code, you will find the ```gnss-sdr``` executable file at gnss-sdr/install. You can make it available everywhere else by ```sudo make install```. Run the profilers ```volk_profile``` and ```volk_gnsssdr_profile``` for testing all available VOLK kernels for each architecture supported by your processor. This only has to be done once.
2. In post-processing mode, you have to provide a captured GNSS signal file.
1. The signal file can be easily recorded using the GNU Radio file sink in ```gr_complex<float>``` mode.
2. You will need a GPS active antenna, a [USRP](http://www.ettus.com/product) and a suitable USRP daughter board to receive GPS L1 C/A signals. GNSS-SDR require to have at least 2 MHz of bandwidth in 1.57542 GHz. (remember to enable the DC bias with the daughter board jumper).

We use a [DBSRX2](https://www.ettus.com/product/details/DBSRX2) to do the task, but you can try the newer Ettus' daughter boards as well.
3. The easiest way to capture a signal file is to use the GNU Radio Companion GUI. Only two blocks are needed: a USRP signal source connected to complex float file sink. You need to tune the USRP central frequency and decimation factor using USRP signal source properties box. We suggest using a decimation factor of 20 if you use the USRP2. This will give you 100/20 = 5 MSPS which will be enough to receive GPS L1 C/A signals. The front-end gain should also be configured. In our test with the DBSRX2 we obtained good results with ```G=50```.
4. Capture at least 80 seconds of signal in open sky conditions. During the process, be aware of USRP driver buffer underruns messages. If your hard disk is not fast enough to write data at this speed you can capture to a virtual RAM drive. 80 seconds of signal at 5 MSPS occupies less than 3 Gbytes using ```gr_complex<float>```.
5. If you have no access to an RF front-end, you can download a sample raw data file (that contains GPS and Galileo signals) from [here](http://sourceforge.net/projects/gnss-sdr/files/data/).

Hence, the application defines a simple accessor class to fetch the configuration pairs of values and passes them to a factory class called [GNSSBlockFactory](./src/core/receiver/gnss_block_factory.h). This factory decides, according to the configuration, which class needs to be instantiated and which parameters should be passed to the constructor. Hence, the factory encapsulates the complexity of blocks' instantiation. With that approach, adding a new block that requires new parameters will be as simple as adding the block class and modifying the factory to be able to instantiate it. This loose coupling between the blocks' implementations and the syntax of the configuration enables extending the application capacities in a high degree. It also allows producing fully customized receivers, for instance a testbed for acquisition algorithms, and to place observers at any point of the receiver chain.

#### Acquisition
The first task of a GNSS receiver is to detect the presence or absence of in-view satellites. This is done by the acquisition system process, which also provides a coarse estimation of two signal parameters: the frequency shift with respect to the nominal IF frequency, and a delay term which allows the receiver to create a local code aligned with the incoming code. [AcquisitionInterface](./src/core/interfaces/acquisition_interface.h) is the common interface for all the acquisition algorithms and their corresponding implementations. Algorithms' interface, that may vary depending on the use of information external to the receiver, such as in Assisted GNSS, is defined in classes referred to as *adapters*. These adapters wrap the GNU Radio blocks interface into a compatible interface expected by AcquisitionInterface. This allows the use of existing GNU Radio blocks derived from ```gr::block```, and ensures that newly developed implementations will also be reusable in other GNU Radio-based applications. Moreover, it adds still another layer of abstraction, since each given acquisition algorithm can have different implementations (for instance using different numerical libraries). In such a way, implementations can be continuously improved without having any impact neither on the algorithm interface nor the general acquisition interface.

* **NMEA 0183** is a combined electrical and data specification for communication between marine electronics such as echo sounder, sonars, anemometer, gyrocompass, autopilot, GPS receivers and many other types of instruments. It has been defined by, and is controlled by, the U.S. [National Marine Electronics Association](http://www.nmea.org/). The NMEA 0183 standard uses a simple ASCII, serial communications protocol that defines how data are transmitted in a *sentence* from one *talker* to multiple *listeners* at a time. Through the use of intermediate expanders, a talker can have a unidirectional conversation with a nearly unlimited number of listeners, and using multiplexers, multiple sensors can talk to a single computer port. At the application layer, the standard also defines the contents of each sentence (message) type, so that all listeners can parse messages accurately. Those messages can be sent through the serial port (that could be for instance a Bluetooth link) and be used/displayed by a number of software applications such as [gpsd](http://www.catb.org/gpsd/ "The UNIX GPS daemon"), [JOSM](https://josm.openstreetmap.de/ "The Java OpenStreetMap Editor"), [OpenCPN](http://opencpn.org/ocpn/ "Open Chart Plotter Navigator"), and many others (and maybe running on other devices).

* **RINEX** (Receiver Independent Exchange Format) is an interchange format for raw satellite navigation system data, covering observables and the information contained in the navigation message broadcast by GNSS satellites. This allows the user to post-process the received data to produce a more accurate result (usually with other data unknown to the original receiver, such as better models of the atmospheric conditions at time of measurement). RINEX files can be used by software packages such as [GPSTk](http://www.gpstk.org), [RTKLIB](http://www.rtklib.com/) and [gLAB](http://gage14.upc.es/gLAB/). GNSS-SDR by default generates RINEX version [3.02](https://igscb.jpl.nasa.gov/igscb/data/format/rinex302.pdf). If [2.11](https://igscb.jpl.nasa.gov/igscb/data/format/rinex211.txt) is needed, it can be requested through the `rinex_version` parameter in the configuration file:

* **RTCM SC-104** provides standards that define the data structure for differential GNSS correction information for a variety of differential correction applications. Developed by the Radio Technical Commission for Maritime Services ([RTCM](http://www.rtcm.org/overview.php#Standards "Radio Technical Commission for Maritime Services")), they have become an industry standard for communication of correction information. GNSS-SDR implements RTCM version 3.2, defined in the document *RTCM 10403.2, Differential GNSS (Global Navigation Satellite Systems) Services - Version 3* (February 1, 2013), which can be [purchased online](https://ssl29.pair.com/dmarkle/puborder.php?show=3 "RTCM Online Publication Order Form"). By default, the generated RTCM binary messages are dumped into a text file in hexadecimal format. However, GNSS-SDR is equipped with a TCP/IP server, acting as an NTRIP source that can feed an NTRIP server. NTRIP (Networked Transport of RTCM via Internet Protocol) is an open standard protocol that can be freely downloaded from [BKG](http://igs.bkg.bund.de/root_ftp/NTRIP/documentation/NtripDocumentation.pdf "Networked Transport of RTCM via Internet Protocol (Ntrip) Version 1.0"), and it is designed for disseminating differential correction data (*e.g.* in the RTCM-104 format) or other kinds of GNSS streaming data to stationary or mobile users over the Internet. The TCP/IP server can be enabled by setting ```PVT.flag_rtcm_server=true``` in the configuration file, and will be active during the execution of the software receiver. By default, the server will operate on port 2101 (which is the recommended port for RTCM services according to the Internet Assigned Numbers Authority, [IANA](http://www.iana.org/assignments/service-names-port-numbers "Service Name and Transport Protocol Port Number Registry")), and will identify the Reference Station with ID=1234.

In order to start using GNSS-SDR, you may want to populate ```gnss-sdr/data``` folder (or anywhere else on your system) with raw data files. By "raw data" we mean the output of a Radio Frequency front-end's Analog-to-Digital converter. GNSS-SDR needs signal samples already in baseband or in passband, at a suitable intermediate frequency (on the order of MHz). Prepare your configuration file, and then you are ready for running ```gnss-sdr --config_file=your_configuration.conf```, and seeing how the file is processed.
Another interesting option is working in real-time with an RF front-end. We provide drivers for UHD-compatible hardware such as the [USRP family](http://www.ettus.com/product), for OsmoSDR and other front-ends (HackRF, bladeRF, LimeSDR), for the GN3S v2 USB dongle and for some DVB-T USB dongles. Start with a low number of channels and then increase it in order to test how many channels your processor can handle in real-time.

## [Unreleased](https://github.com/gnss-sdr/gnss-sdr/tree/next)
Next release will have several improvements in different dimensions, addition of new features and bug fixes:
### Improvements in Accuracy:
- Part of the RTKLIB core library has been integrated into GNSS-SDR. There is now a single PVT block implementation which makes use of RTKLIB to deliver PVT solutions, including Single and PPP navigation modes.
- Fixed CN0 estimation for other correlation times than 1 ms.
- Improved computation of tracking parameters and GNSS observables.
- Other minor bug fixes.
### Improvements in Availability:
- Internal Finite State Machines rewritten for improved continuity in delivering position fixes. This fixes a bug that was stalling the receiver after about six hours of continuous operation.
- Redesign of the time counter for enhanced continuity.
- Improved flow graph in multisystem configurations: the receiver does not get stalled anymore if no signal is found from the first system.
- Improved acquisition and tracking sensitivity.
- Other minor bug fixes.
### Improvements in Efficiency:
- Added the possibility of non-blocking acquisition, which works well when using real-time data from an RF front-end.
- Improved flow graph in multiband configurations: satellites acquired in one band are immediately searched in others.
- Complex local codes have been replaced by real codes, alleviating the computational burden.
- New volk_gnsssdr kernels: volk_gnsssdr_16i_xn_resampler_16i_xn.h, volk_gnsssdr_16ic_16i_rotator_dot_prod_16ic_xn.h, volk_gnsssdr_32f_xn_resampler_32f_xn.h, volk_gnsssdr_32fc_32f_rotator_dot_prod_32fc_xn.h
- Some AVX2 implementations added to the volk_gnsssdr library.
- Improvement in C++ usage: Use of const container calls when result is immediately converted to a const iterator. Using these members removes an implicit conversion from iterator to const_iterator.
- A number of code optimizations here and there.
### Improvements in Flexibility:
- A number of new parameters have been exposed to the configuration system.
- Possibility to choose Pilot or Data component for tracking of GPS L5 and Galileo E5a signals.
- Enabled extended coherent integration times.
- Some configuration parameters can now be overridden by commandline flags for easier use in scripts.
### Improvements in Interoperability:
- Added the GPS L5 receiver chain.
- Added the GLONASS L1 SP receiver chain.
- Added the GLONASS L2 SP receiver chain.
- Improvements in the Galileo E5a and GPS L2C receiver chains.
- Updated list of available GNSS satellites.
- Added five more signal sources: "Fmcomms2_Signal_Source" (requires gr-iio), "Plutosdr_Signal Source" (requires gr-iio), "Spir_GSS6450_File_Signal_Source", "Labsat_Signal_Source" and "Custom_UDP_Signal_Source" (requires libpcap). Documented in https://gnss-sdr.org/docs/sp-blocks/signal-source/
- Improved support for BladeRF, HackRF and RTL-SDR front-ends.
- Added tools for the interaction with front-ends based on the AD9361 chipset.
- Intermediate results are now saved in .mat binary format, readable from Matlab/Octave and from Python via h5py.
- Added the GPX output format.
- Fixed a bug in the format of NMEA sentences when latitude or longitude minutes were >10.
- Improvements in the RTCM server stability.
- Improvements in the correctness of generated RINEX files.
### Improvements in Maintainability:
- Setup of a Continuous Integration system that checks building and runs QA code in a wide range of GNU/Linux distributions (ArchLinux, CentOS, Debian, Fedora, OpenSUSE, Ubuntu) and releases. See https://gitlab.com/gnss-sdr/gnss-sdr
- Creation of multi-system processing blocks, drastically reducing code duplication and maintainability time.
- Automated code formatting with clang-format. This tool is widely available and easy to integrate into many code editors, and it also can be used from the command line. It cuts time spent on adhering to the project's code formatting style.
- Improvement in C++ usage: C-style casts have been replaced by C++ casts. C-style casts are difficult to search for. C++ casts provide compile time checking ability and express programmers' intent better, so they are safer and clearer.
- Improvement in C++ usage: The override special identifier is now used when overriding a virtual function. This helps the compiler to check for type changes in the base class, making the detection of errors easier.
- Improvement in C++ usage: A number of unused includes have been removed. Order of includes set to: local (in-source) headers, then library headers, then system headers. This helps to detect missing includes.
- Improvement in C++ usage: Enhanced const correctness. Misuses of those variables are detected by the compiler.
### Improvements in Portability:
- Several CMake scripts improvements, more verbose outputs in case of errors. Building configuration has been documented in https://gnss-sdr.org/docs/tutorials/configuration-options-building-time/
- Improved SDK for cross-compilation in embedded devices. Documented in https://gnss-sdr.org/docs/tutorials/cross-compiling/
- Improved control over minimum required versions for core dependencies.
- The software builds with C++11, C++14 and C++17 standards.
- The software can now be built using GCC >= 4.7.2 or LLVM/Clang >= 3.4.0 compilers on GNU/Linux, and with Clang/AppleClang on MacOS.
- The Ninja build system can be used in replacement of make.
- The volk_gnsssdr library can be built using Python 2.7 or Python 3.6.
- The volk_gnsssdr library is now ready for AArch64 NEON instructions.

- Improvement in C++ usage: The <stdio.h> library has been replaced by the more modern and portable <fstream> for file handling.
- Improvement in C++ usage: C++ libraries preferred over C libraries (e.g., <cctype> instead of <ctype.h>, <cmath> instead of <math.h>).
- Fixes required by Debian packaging.
- Fixes required by Macports packaging.
- A downside in portability: BLAS and LAPACK libraries are now required even in ARM devices.
- A downside in portability: the matio library >= 1.5.3 is a new required dependency. If not found, it is downloaded and built automatically at building time, but this requires libtool, automake and hdf5 already installed in the system.
### Improvements in Reliability:
- Introduced 3 new Input Filter implementations for pulsed and narrowband interference mitigation: `Pulse_Blanking_Filter`, `Notch_Filter` and `Notch_Filter_Lite`. Documented in https://gnss-sdr.org/docs/sp-blocks/input-filter/

- Improvement in C++ usage: rand() function replaced by <random> library.
- Improvement in C++ usage: strlen and strncpy have been replaced by safer C++ counterparts.
- Improvement in C++ usage: Some destructors have been fixed, avoiding segmentation faults when exiting the program.
- Website switched from http to https. Links in the source tree switched when available.
### Improvements in Reproducibility:
- Setup of a Continuous Reproducibility system at GitLab for the automatic reproduction of experiments. The concept was introduced in https://ieeexplore.ieee.org/document/8331069/ Example added in the src/utils/reproducibility/ieee-access18/ folder.
- Fixes of Lintian warnings related to build reproducibility.
### Improvements in Scalability:
- Improvements in multi-system, multi-band receiver configurations. The receiver now accepts any number of channels and systems in the three available bands.

- Improvements in receiver design: Internal block communication has been redesigned to accommodate the addition of new signals, and now upstream and downstream communication within blocks is implemented through the GNU Radio block’s asynchronous message passing system, leading to a more scalable, more robust and cleaner design.
- Improvements in receiver design: Correlators have been rewritten to take full advantage of VOLK and VOLK_GNSSSDR, and they are of general use for any tracking block. Their API now admit an arbitrary number of correlators, spaced in an arbitrary manner, in 16ic and 32fc versions.
- Improvements in receiver design: Block adapters are now all managed by smart pointers, ensuring better memory management.
- Improvements in receiver design: Block adapters are now all managed by smart pointers, ensuring better memory management.
- Improvements in processing speed: The VOLK_GNSSSDR library has been rewritten, following current VOLK standards and adding a number of new kernels. This approach addresses both efficiency and portability. Now the library provides the key kernels for GNSS signal processing in 16ic and 32fc versions, including SSE2, SSE3, SSE4.1, AVX, AV2 and NEON implementations. Please execute volk_gnsssdr_profile and volk_profile to use the fastest implementation for your host machine.
- New source block: Two_Bit_Packed_File_Signal_Source. This block takes 2 bit samples that have been packed into bytes or shorts as input and generates a byte for each sample.
- Fixes in SUPL assistance (supl.nokia.com removed).
- Improvements in acquisition: Added a non CFAR PCPS acquisition algorithm based on the estimation of the post correlation noise floor. If enabled as an option in the acquisition configuration, it allows setting more stable thresholds in the presence of non-gaussian front-end noise (which is the usual behavior of front-ends.)

- New tracking block introduced: GPS_L1_CA_DLL_PLL_Tracking_GPU is a GPS L1 C/A carrier PLL and code DLL that uses the CUDA-compatible GPU to compute carrier wipe off and correlation operations, alleviating the CPU load.
- Obsolete/buggy blocks removed: GPS_L1_CA_DLL_FLL_PLL_Tracking, GPS_L1_CA_DLL_PLL_Optim_Tracking.
- Added a RTCM printer and TCP server in PVT blocks (still experimental). The receiver is now able to stream data in real time, serving RTCM 3.2 messages to multiple clients. For instance, it can act as a Ntrip Source feeding a Ntrip Server, or to be used as data input in RTKLIB, obtaining Precise Point Positioning fixes in real-time. The TCP port, Station ID, and rate of MT1019/MT1045 and MSM can be configured. GPS_L1_CA_PVT serves MT1019 (GPS Ephemeris) and MSM7 (MT1077, full GPS pseudoranges, phase ranges, phase range rates and CNR - high resolution) messages, while GALILEO_E1_PVT serves MT1045 (Galileo ephemeris) and MSM7 (MT1097, full Galileo pseudoranges, phase ranges, phase range rates and CNR - high resolution).
- Added a GeoJSON printer. Basic (least-squares) position fixes can be now also stored in this format, in addition to KML.

\section overview Overview
GNSS-SDR provides an interface to different suitable RF front-ends and implements all the receiver chain up to the navigation solution.
Its design allows any kind of customization, including interchangeability of signal sources, signal processing algorithms,
interoperability with other systems, output formats, and offers interfaces to all the intermediate signals, parameters and variables.
The goal is to write efficient and truly reusable code, easy to read and maintain, with fewer bugs, and producing highly optimized executables
in a variety of hardware platforms and operating systems. In that sense, the challenge consists of defining a gentle balance within level
of abstraction and performance. GNSS-SDR runs in a personal computer and provides interfaces through USB and Ethernet

GNSS-SDR's main method initializes the logging library, processes the command line flags, if any, provided by the user and instantiates a ControlThread object.
Its constructor reads the configuration file, creates a control queue and creates a flowgraph according to the configuration. Then, the program's main method
calls the run() method of the instantiated object, an action that connects the flowgraph and starts running it. After that, and until a stop message is received,
it reads control messages sent by the receiver's modules through a safe-thread queue and processes them. Finally, when a stop message is received, the main

The GNSSFlowgraph class is responsible for preparing the graph of blocks according to the configuration, running it, modifying it during run-time and stopping it.
Blocks are identified by its role. This class knows which roles it has to instantiate and how to connect them.
It relies on the configuration to get the correct instances of the roles it needs and then it applies the connections between GNU Radio blocks to make the

The GNSSFlowgraph class is responsible for preparing the graph of blocks according to the configuration, running it, modifying it during run-time and stopping it.
Blocks are identified by its role. This class knows which roles it has to instantiate and how to connect them.
It relies on the configuration to get the correct instances of the roles it needs and then it applies the connections between GNU Radio blocks to make the

estimations of the receiver position in order to avoid searching satellites in the other side of the Earth.
The Control Plane is in charge of creating a flowgraph according to the configuration and then managing the modules. Configuration allows users to define in an easy way their own
custom receiver by specifying the flowgraph (type of signal source, number of channels, algorithms to be used for each channel and each module, strategies for
satellite selection, type of output format, etc.). Since it is difficult to foresee what future module implementations will be needed in terms of configuration,
we used a very simple approach that can be extended without a major impact in the code. This can be achieved by simply mapping the names of the variables in the
custom receiver by specifying the flowgraph (type of signal source, number of channels, algorithms to be used for each channel and each module, strategies for
satellite selection, type of output format, etc.). Since it is difficult to foresee what future module implementations will be needed in terms of configuration,

modules with the names of the parameters in the configuration.
\subsection configuration Configuration
Properties are passed around within the program using the ConfigurationInterface class. There are two implementations of this interface: FileConfiguration and
InMemoryConfiguration. FileConfiguration reads the properties (pairs of property name and value) from a file and stores them internally. InMemoryConfiguration does
not read from a file; it remains empty after instantiation and property values and names are set using the set property method. FileConfiguration is intended to be
used in the actual GNSS-SDR application whereas InMemoryConfiguration is intended to be used in tests to avoid file-dependency in the file system. Classes that
need to read configuration parameters will receive instances of ConfigurationInterface from where they will fetch the values. For instance, parameters related

\endverbatim
The name of these parameters can be anything but one reserved word: implementation. This parameter indicates in its value the name of the class that has to be instantiated

Since the configuration is just a set of property names and values without any meaning or syntax, the system is very versatile and easily extendable. Adding new
properties to the system only implies modifications in the classes that will make use of these properties. In addition, the configuration files are not checked
against any strict syntax so it is always in a correct status (as long as it contains pairs of property names and values in <a href="http://en.wikipedia.org/wiki/INI_file" target="_blank">INI format</a>).

Hence, the application defines a simple accessor class to fetch the configuration pairs of values and passes them to a factory class called GNSSBlockFactory.
This factory decides, according to the configuration, which class needs to be instantiated and which parameters should be passed to the constructor. Hence, the factory
encapsulates the complexity of blocks' instantiation. With that approach, adding a new block that requires new parameters will be as simple as adding the block
class and modifying the factory to be able to instantiate it. This loose coupling between the blocks' implementations and the syntax of the configuration
enables extending the application capacities in a high degree. It also allows to produce fully customized receivers, for instance a testbed for acquisition

\subsection signal_source Signal Source

The first task of a GNSS receiver is to detect the presence or absence of in-view satellites. This is done by the acquisition system process, which also provides a coarse estimation of two signal parameters: the frequency shift
with respect to the nominal IF frequency, and a delay term which allows the receiver to create a local code aligned with the incoming code.
AcquisitionInterface is the common interface for all the acquisition algorithms and their corresponding implementations. Algorithms' interface, that may vary
depending on the use of information external to the receiver, such as in Assisted GNSS, is defined in classes referred to as <i>adapters</i>.
These adapters wrap the GNU Radio blocks interface into a compatible interface expected by AcquisitionInterface. This allows the use of existing GNU Radio blocks
derived from <tt>gr::block</tt>, and ensures that newly developed implementations will also be reusable in other GNU Radio-based applications.

error correction). Navigation data bits are structured in words, pages, subframes, frames and superframes. Sometimes, bits corresponding to a single parameter are
spread over different words, and values extracted from different frames are required for proper decoding. Some words are for synchronization purposes, others for
error control an others contain actual information. There are also error control mechanisms, from parity checks to forward error correction (FEC) encoding and
interleaving, depending on the system. All this decoding complexity is managed by a finite state machine implemented with the <a href="http://www.boost.org/libs/statechart/doc/tutorial.html" target="_blank">Boost.Statechart library</a>.

GNSS systems provide different kinds of observations. The most commonly used are the code observations, also called pseudoranges. The <i>pseudo</i> comes from
the fact that on the receiver side the clock error is unknown and thus the measurement is not a pure range observation. High accuracy applications also use the
carrier phase observations, which are based on measuring the difference between the carrier phase transmitted by the GNSS satellites and the phase of the carrier
generated in the receiver. Both observables are computed from the outputs of the tracking module and the decoding of the navigation message.

\section now_what Ok, now what?
In order to start using GNSS-SDR, you may want to populate <tt>gnss-sdr/data</tt> folder (or anywhere else on your system) with raw data files. By "raw data" we mean the output
of a Radio Frequency front-end's Analog-to_Digital converter. GNSS-SDR needs signal samples already in baseband or in passband, at a suitable intemediate frequency (on the order of MHz).
In order to start using GNSS-SDR, you may want to populate <tt>gnss-sdr/data</tt> folder (or anywhere else on your system) with raw data files. By "raw data" we mean the output
of a Radio Frequency front-end's Analog-to_Digital converter. GNSS-SDR needs signal samples already in baseband or in passband, at a suitable intemediate frequency (on the order of MHz).
Prepare your configuration file, and then you are ready for going to the <tt> gnss-sdr/install</tt> folder, running <tt>./gnss-sdr</tt>, and see how the file is processed.
Please ask the Developer Team for a signal sample if you need one, and they will do their best ;-)
Another interesting option is working in real-time with a RF front-end. We provide drivers for UHD-compatible hardware (see \ref signal_source), for the GN3S v2 USB dongle
and for some DVB-T USB dongles. Start with a low number of channels and then increase it in order to test how many channels your processor can handle in real-time.
You can find more information at the <a href="http://gnss-sdr.org/docs/" target="_blank"><b>GNSS-SDR Documentation page</b></a> or directly asking to the
<a href="http://lists.sourceforge.net/lists/listinfo/gnss-sdr-developers" target="_blank"><b>GNSS-SDR Developers mailing list</b></a>.
You are also very welcome to contribute to the project, there are many ways to <a href="http://gnss-sdr.org/contribute/" target="_blank"><b>participate in GNSS-SDR</b></a>.
If you need some special feature not yet implemented, the Developer Team would love to be hired for developing it.
Please do not hesitate to <a href="http://gnss-sdr.org/team/" target="_blank"><b>contact them</b></a>.
