f6892a8bf3 It seems that definitions such as 
const bits_slice INTEGRITY_STATUS_FLAG = {{23,1}};

used in GPS_L1_CA.h are not allowed in the C++11 standard since they do not correspond to any valid constructor. This is accepted by the current version of gcc (probably due to backward compatibility with C and earlier versions of C++), but it *could* not be accepted in future versions. This can be fixed by putting the struct into a std::vector. I don't know if this is the best way but it seems to work well and does not implies major changes in the code.

There is another issue with the Gnss_Synchro class. Since it had a constructor and a destructor, it could not be considered a POD (Plain Old Data) structure and this has some limitations: while gcc and the C99 standard allowed an array's size to be determined at run time, this extension is not permitted in standard C++. This issue has implications when passing Gnss_Synchro through memory between signal processing blocks. In order to fix this, I have removed the Gnss_Synchro.cc implementation and now this is a header-only class where the array size can be determined at compile time

9d34147e0f Major update to improve the GNSS-SDR pseudorange precision and correct some PVT bugs: 
- Updated all available trackings to generate the tracking_timestamp_secs taking into account the remainder code phase.
- Updated the telemetry decoder to track the number of symbol shifted from the preamble start symbol (to be used in observables).
- Updated observables to align the reference channel symbol with the corresponding symbols in the other channels and compute pseudorranges using the common transmission time algorithm.
- Updated PVT to independize the display output rate from the RINEX and KML log files. New options available in config file!
- Some minor improvements and code cleaning.

- The executable file and the default configuration file is now changed from "./install/mercurio" and "./conf/mercurio.conf" to "./install/gnss-sdr" and "./conf/gnss-sdr.conf", respectively.
        - Configuration file structure changed to define in a single entry the internal sampling frequency (after the signal conditioner). NOTICE that this change affects the all the adapters (acquisition, tracking, telemetry_decoder, observables, and PVT). All the adapters are now modified to work with this feature.
        - Moved several in-line GPS L1 CA parameters (a.k.a magic numbers..) to ./src/core/system_parameters/GPS_L1_CA.h definition file.
        - Tracking blocks now uses DOUBLE values in their outputs.
        - Observables and PVT now are separated. PVT and their associated libraries are moved to ./src/algorithms/PVT
        - Temporarily disabled the RINEX output (I am working on that!)
        - GNSS-SDR screen output now gives extended debug information of the receiver status and events. In the future, this output will be redirected to a log file.

- Bug fixes:
        - FILE_SIGNAL_SOURCE now works correctly when the user configures GNSS-SDR to process the entire file.
        - GPS_L1_CA_DLL_PLL now computes correctly the PRN start values.
        - GPS_L1_CA_DLL_FLL_PLL now computes correctly the PRN start values.
        - Several modifications in GPS_L1_CA_Telemetry_Decoder, GPS_L1_CA_Observables, and GPS_L1_CA_PVT modules to fix the GPS position computation.

- New features
        - Tracking blocks perform a signal integrity check against NaN outliers before the correlation process.
        - Tracking and PVT binary dump options are now documented and we provide MATLAB libraries and sample files to read it. Available in ./utils/matlab" and "./utils/matlab/libs"
        - Observables output rate can be configured. This option enables the GPS L1 CA PVT computation at a maximum rate of 1ms.
        - GPS_L1_CA_PVT now can perform a moving average Latitude, Longitude, and Altitude output for each of the Observables output. It is configurable using the configuration file.
        - Added Google Earth compatible Keyhole Markup Language (KML) output writer class (./src/algorithms/PVT/libs/kml_printer.h and ./src/algorithms/PVT/libs/kml_printer.cc ). You can see the receiver position directly using Google Earth.
        - We provide a master configuration file which includes an in-line documentation with all the new (and old) options. It can be found in ./conf/master.conf

34d1c5110b GNSS-SDR Major changes: 
New tracking libraries:
        -  tracking_discriminators: Library with a set of code tracking and carrier tracking discriminators that is used by the tracking algorithms. (fully documented, including math algorithms using doxygen!)
        -  tracking_2rd_DLL_filter: Class that implements 2 order DLL filter for code tracking loop.
        -  tracking_2rd_PLL_filter: Class that implements 2 order PLL filter for carrier tracking loop.
        -  tracking_FLL_PLL_filter:  Class that implements hybrid FLL and PLL filter for tracking carrier loop.
        -  CN_estimators: Library with a set of Carrier to Noise estimators and lock detectors. (fully documented, including math algorithms using doxygen!)

    Tracking:
        - gps_l1_ca_dll_pll_tracking: The existing DLL + PLL tracking module, which is the K.Borre and D.Akos one, is now completely re-factored. Now uses the above described libraries.
        - gps_l1_ca_dll_fll_pll_tracking: This is a brand new tracking module, which implements the FLL assisted PLL described in Kaplan (2nd edition). (also documentedwith references)

    Configuration options:
        - The following tracking parameters are added:
            ;######### TRACKING CONFIG ############
            ; Tracking.implementation=GPS_L1_CA_DLL_PLL_Tracking or GPS_L1_CA_DLL_FLL_PLL_Tracking 
            Tracking.implementation=GPS_L1_CA_DLL_FLL_PLL_Tracking
            ;PLL filter bandwidth in Hz.
            Tracking.pll_bw_hz=50.0;
            ;DLL filter bandwidth in Hz.
            Tracking.dll_bw_hz=2.0;
            ;FLL filter bandwidth in Hz.
            Tracking.fll_bw_hz=50;
            ;filter order: choice between 2 or 3 at this moment, only for FLL assisted PLL
            Tracking.order=2;
            ;Correlator space in chips units
            Tracking.early_late_space_chips=0.5;

Other files have also been modified with minor changes to adapt to new modules or minor bug fixes.

1040e6865d Added J.Arribas contributions: PVT with basic least squares and rinex 2.1 output is now enabled, tracking channels now estimate the CN0 and performs a basic carrier lock detector and returns to acquisition if the tracking loss the lock.
