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!)

bcd90ca9cf Removing unused code that could prevent binaries to run on machines 
where the set of SIMD instructions is not the same than the machine that
compiled them.

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.

39f8754217 Cleaning the terminal output and dumping most of the information in the log file. Better use of the glog library, logging can be seen also in Release, in real time by doing './gnss-sdr --logtostderr=1'. Update to latest version of Armadillo.

4d66f6c6ab - Galileo channels now supports all the published PRN IDs in acquisition and tracking 
- Changes in Galileo telemetry decoding (still under construction)
- Bug correction in tracking blocks that could cause random segmentation faults on some configurations

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.

a25e712be6 Bug correction for acquisition and tracking: acquisition Doppler sign were inverted and this issue caused several wrong interpretations in tracking algorithms, resulting in a swap in I/Q components. Now the bug was corrected in all tracking algorithms.
