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.
- Bug fixes at Galileo telemetry decoder state machine
- Bug fixes at Galileo Ephemeris decoder (two complement's data interpreted as unsigned, mismatch at the LSB weights)
Galileo KML output is avalable!!
Galileo RINEX is still under construction

Bug fix in galileo tracking
Several improvements in Galileo telemetry decoder.
Code cleaning in observables
Galileo PVT is able to decode Galileo time and get satellite ECEF positions
Galileo PVT soluton is still under development

- Some channel and acquisition properties are now common for all channels
- You can choose between channel-specific properties or properties common to all
- Updating config file with the new options

- 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.

- 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!)

- 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.

- Added a pre-compiled custom GN3S firmware.
- Added a fully-compliant GNU Radio source block for GN3S USB dongle. It can be used also from GNU Radio companion and from Python applications.
- Added a new GN3S_Signal_Source block. It is possible to disable the GN3S signal source compilation. See README.

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

- 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.
