Added a new protokernel to substitute update_local_code function,
inside tracking: volk_gnsssdr_32fc_s32f_x4_update_local_code_32fc
Volk implementation is 7x times faster than generic implementation.
Improved 8ic_x7_cw_epl_corr_32fc_x5 protokernels and added a new
protokernel called volk_gnsssdr_32fc_convert_8ic in order to test the 8
bits protokernels in the tracking.
Created the proto-kernels volk_gnsssdr_8ic_x7_cw_epl_corr_32fc_x5 and
volk_gnsssdr_8ic_x7_cw_epl_corr_TEST_32fc_x5
Created two new quicker implementations for
volk_gnsssdr_8ic_x7_cw_epl_corr_32fc_x5 and their macros:
volk_gnsssdr_8ic_x7_cw_epl_corr_safe_32fc_x5
volk_gnsssdr_8ic_x7_cw_epl_corr_unsafe_32fc_x5
Modified the templates of the module volk_gnsssdr to generate the
header files with some changes that allow running volk_gnsssdr
functions and volk standard functions at the same time in a file.

- Updated Unit Test to benchmark all the current NCO implementations (./run_tests --gtest_filter=Cordic_Test.StandardCIsFasterThanCordic)
-Gps_L1_Ca_Dll_Pll_Optim_Tracking algorithm updated with new NCO library for carrier wipeoff and some other optimizations.

- Improved speed for normalization in the FFTW results
- Complex multiplications now use the SIMD instructions with VOLK library
- Carrier wipeoff now uses the GNU Radio fixed point NCO (gr_fxpt)

1) Galileo E1 Acquisition adapter block added (Gnuradio block modification to use the same block with the 2 systems with 2 adapters)
2) Tests and signal samples for Galileo E1 Acquisition signal block
3) Library for Galileo E1 signal processing
4) Galileo_E1.h with constant variables for this system

boost::filesystem::temp_directory_path() is only available from Boost 1.45, while Ubuntu 10.10 comes with Boost 1.42.

- 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
