322550e0c6 Adding an option to build the binary without detecting the SIMD 
instruction set present in the compiling machine, so it can be executed
in other machines without those specific sets.

072d0cad67 Important bug found and fixed: 
Volk memory alignement for signal vectors was using a hardcoded 16 bytes
value. This parameter is machine-dependant and thus, in modern machines
caused memory exceptions if the parameter not match.

All posix_memalign functions are now replaced by the GNU Radio
volk_malloc(vector_size (bytes), volk_get_alignement());

volk_get_alignement() returns the number of bytes to align the memory
blocks in the current processor.

The memory bug showed up when the receiver is configured with higher
sample rates (>4 Msps!)

abe9ca9450 Hybrid PVT working!! It was a problem with the timestamp account in the 
correlators due to the differences in the correlation time (PRN length).
Only corrected on GPS_DLL_PLL and Galileo veml correlator.

b0d33328d5 Simultaneous multi-GNSS system acquisition, tracking and telemetry 
decoding: Changes in the flowgraph and in the configuration files to mix
channels from different GNSS systems in the same receiver. Hybrid
observables and PVT under construction.

The changes in the configuration file parameter names are NOT backward
compatible. The receiver can still work as usual in single GNSS system
mode but some modification on configuration files are required. Use the
example provided of Hybrid configuration file.

885c5f364c Small bug fix and new configuration file ready to receive GPS signals in real-time with USRP devices and appropiate front-ends. Remember to tune the front-end gain (source section in config file) and, in some particular antenna and LNA setups, tune also the acquisition threshold (acquisition section). The configuration is tested on USRP v1 + DBSRX, USRP 2 + DBSRX and USRP B100 + WBX.

e728450192 New feature (FE01): RINEX v 2.11 now outputs the following observables: 
PSEUDORANGE
CARRIER PHASE
CARRIER DOPPLER
SIGNAL STRENGTH (dB-Hz)

thus, it enables the realtime kinematics and PPP positioning for first time in an open source GNSS SDR. Enjoy!

0760fa0f3e - New NCO library for carrier signal generation: Provides a fixed point optimized wrapper for GNU Radio fxp CORDIC and SSE2 floating point implementation ( sse_mathfunc.h implementation). The library is available as nco_lib.h 
- 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.
