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!)

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.

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.
