74817d6d07 · Non-optimised multi-dwell acquisition with fine doppler estimation is now enabled in the block factory (It is used by the front-end calibration utility). It can be instantiated from the configuration file. 
· Bug fixed in the configuration parser that prevented the use of non-integer thresholds
· Provisional patch added to disable the PVT output if the height is above 50 km (due to a random bug that appears with some satellite configurations..)

3e87d1f204 Major update: 
- The GNSS-SDR code-based Observable generation algorithm for GPS L1 C/A was migrated from common TX time to common RX time. One of the main reasons is that the common TX algorithm was incompatible with the standard RINEX observables, wich requires the oservables at the same time of reception.
- Using common Rx time, the code was simplified and now requires less memory due to the lack of symbol buffer

- Now it is possible to use standard RINEX post processing software (gpstk and rtklib for instance) to get PVT and the obtained precision is comparable to the internal Least Squares solver. It is possible to use also the carrier phase observable, but is still experimental.

- The default RINEX version output was set to 2.11 in this revision.  RINEX 3.00 is under verification now.

0bf9e44eb4 SUPL assistance support in progress: 
- New SUPL parameters available in GNSS-SDR.conf
- Ephemeris assistance for real-time operation is now functional
- SUPL client now stores the received ephemeris in XML file. This file can be loaded on request to enable post-processing SUPL assistance and to enable SUPL assistance without internet connection. -> thowards a complete warm start GNSS-SDR.

BUG FIXES:
- GN3S driver firmware file copy operation in CmakeLists.txt had an error that mismatches the gn3s_firmware.ihx file location and prevents the correct firmware loading for GN3S SiGe USB dongles.

8b2d21c1c9 Major changes: 
- Gps telemetry decoder and PVT now uses independent queues for ephemeris, iono, utc_model and almanac. The old gps_navigation_queue is now deprecated and it is removed from the implementation. This affect almost all the PVT and Rinex printer classes.
- Rinex printer class updated to use the new ephemeris, iono, utc_model objects
Bug fixes and correction:
- The pseudorange generation now is based on the computed TOW for each received symbol. The History_Shift computation become simplier in this way. This modification is also a solution for a bug where the pseudoranges became temporally invalid when the TOW is updated (that happen every 6 secons!)

201b446c47 Added build support for the GN3S dongle. If the variable GN3S_DRIVER is set, CMake automatically builds the gr-gn3s project, adds the gn3s_signal_source and links the corresponding library. There is no need to have gr-gn3s already installed. 
Example:
$ cd build
$ export GN3S_DRIVER=1
$ cmake ../
$ make
$ make install

The gr-gn3s project can be build and installed independently, for instance for using it as a source block in gnuradio-companion.

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

- 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.

0d598a7188 Added implementation of plain cordic class in tracking/libs. Added a corresponding test. The implementation is slower than standard sin and cos implementations, so it is not used in the receiver. The test will fail otherwise, indicating that this should be used instead of standard functions.

69b8ac00dc - Major changes: 
- 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

004cd776d9 BUG FIX: Now the file_signal_source obeys the SignalSource.samples configuration parameter in the conf file. This fix allows limiting the number of samples to be processed by the receiver.

dcc3e4d858 Change of the set_doppler_freq_shift(float phase) to set_doppler_freq_shift(float doppler_freq_hz), and set_prn_code_phase(signed int phase) to set_prn_code_phase(signed int phase_samples), which are more appropiate, in tracking_interface. Minor changes in tracking adapters to be coherent with the new variable names
