74817d6d07 · Non-optimised multi-dwell acquisition with fine doppler estimation is now enabled in the block factory (It is used by the front-end calibration utility). It can be instantiated from the configuration file. 
· Bug fixed in the configuration parser that prevented the use of non-integer thresholds
· Provisional patch added to disable the PVT output if the height is above 50 km (due to a random bug that appears with some satellite configurations..)

3e87d1f204 Major update: 
- The GNSS-SDR code-based Observable generation algorithm for GPS L1 C/A was migrated from common TX time to common RX time. One of the main reasons is that the common TX algorithm was incompatible with the standard RINEX observables, wich requires the oservables at the same time of reception.
- Using common Rx time, the code was simplified and now requires less memory due to the lack of symbol buffer

- Now it is possible to use standard RINEX post processing software (gpstk and rtklib for instance) to get PVT and the obtained precision is comparable to the internal Least Squares solver. It is possible to use also the carrier phase observable, but is still experimental.

- The default RINEX version output was set to 2.11 in this revision.  RINEX 3.00 is under verification now.

PSEUDORANGE

0bf9e44eb4 SUPL assistance support in progress: 
- 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.

8b2d21c1c9 Major changes: 
- 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!)
