- Major changes:
- The executable file and the default configuration file is now changed from "./install/mercurio" and "./conf/mercurio.conf" to "./install/gnss-sdr" and "./conf/gnss-sdr.conf", respectively.
- Configuration file structure changed to define in a single entry the internal sampling frequency (after the signal conditioner). NOTICE that this change affects the all the adapters (acquisition, tracking, telemetry_decoder, observables, and PVT). All the adapters are now modified to work with this feature.
- Moved several in-line GPS L1 CA parameters (a.k.a magic numbers..) to ./src/core/system_parameters/GPS_L1_CA.h definition file.
- Tracking blocks now uses DOUBLE values in their outputs.
- Observables and PVT now are separated. PVT and their associated libraries are moved to ./src/algorithms/PVT
- Temporarily disabled the RINEX output (I am working on that!)
- GNSS-SDR screen output now gives extended debug information of the receiver status and events. In the future, this output will be redirected to a log file.
- Bug fixes:
- FILE_SIGNAL_SOURCE now works correctly when the user configures GNSS-SDR to process the entire file.
- GPS_L1_CA_DLL_PLL now computes correctly the PRN start values.
- GPS_L1_CA_DLL_FLL_PLL now computes correctly the PRN start values.
- Several modifications in GPS_L1_CA_Telemetry_Decoder, GPS_L1_CA_Observables, and GPS_L1_CA_PVT modules to fix the GPS position computation.
- New features
- Tracking blocks perform a signal integrity check against NaN outliers before the correlation process.
- Tracking and PVT binary dump options are now documented and we provide MATLAB libraries and sample files to read it. Available in ./utils/matlab" and "./utils/matlab/libs"
- Observables output rate can be configured. This option enables the GPS L1 CA PVT computation at a maximum rate of 1ms.
- GPS_L1_CA_PVT now can perform a moving average Latitude, Longitude, and Altitude output for each of the Observables output. It is configurable using the configuration file.
- Added Google Earth compatible Keyhole Markup Language (KML) output writer class (./src/algorithms/PVT/libs/kml_printer.h and ./src/algorithms/PVT/libs/kml_printer.cc ). You can see the receiver position directly using Google Earth.
- We provide a master configuration file which includes an in-line documentation with all the new (and old) options. It can be found in ./conf/master.conf

- Major changes:
- The executable file and the default configuration file is now changed from "./install/mercurio" and "./conf/mercurio.conf" to "./install/gnss-sdr" and "./conf/gnss-sdr.conf", respectively.
- Configuration file structure changed to define in a single entry the internal sampling frequency (after the signal conditioner). NOTICE that this change affects the all the adapters (acquisition, tracking, telemetry_decoder, observables, and PVT). All the adapters are now modified to work with this feature.
- Moved several in-line GPS L1 CA parameters (a.k.a magic numbers..) to ./src/core/system_parameters/GPS_L1_CA.h definition file.
- Tracking blocks now uses DOUBLE values in their outputs.
- Observables and PVT now are separated. PVT and their associated libraries are moved to ./src/algorithms/PVT
- Temporarily disabled the RINEX output (I am working on that!)
- GNSS-SDR screen output now gives extended debug information of the receiver status and events. In the future, this output will be redirected to a log file.
- Bug fixes:
- FILE_SIGNAL_SOURCE now works correctly when the user configures GNSS-SDR to process the entire file.
- GPS_L1_CA_DLL_PLL now computes correctly the PRN start values.
- GPS_L1_CA_DLL_FLL_PLL now computes correctly the PRN start values.
- Several modifications in GPS_L1_CA_Telemetry_Decoder, GPS_L1_CA_Observables, and GPS_L1_CA_PVT modules to fix the GPS position computation.
- New features
- Tracking blocks perform a signal integrity check against NaN outliers before the correlation process.
- Tracking and PVT binary dump options are now documented and we provide MATLAB libraries and sample files to read it. Available in ./utils/matlab" and "./utils/matlab/libs"
- Observables output rate can be configured. This option enables the GPS L1 CA PVT computation at a maximum rate of 1ms.
- GPS_L1_CA_PVT now can perform a moving average Latitude, Longitude, and Altitude output for each of the Observables output. It is configurable using the configuration file.
- Added Google Earth compatible Keyhole Markup Language (KML) output writer class (./src/algorithms/PVT/libs/kml_printer.h and ./src/algorithms/PVT/libs/kml_printer.cc ). You can see the receiver position directly using Google Earth.
- We provide a master configuration file which includes an in-line documentation with all the new (and old) options. It can be found in ./conf/master.conf

- Major changes:
- The executable file and the default configuration file is now changed from "./install/mercurio" and "./conf/mercurio.conf" to "./install/gnss-sdr" and "./conf/gnss-sdr.conf", respectively.
- Configuration file structure changed to define in a single entry the internal sampling frequency (after the signal conditioner). NOTICE that this change affects the all the adapters (acquisition, tracking, telemetry_decoder, observables, and PVT). All the adapters are now modified to work with this feature.
- Moved several in-line GPS L1 CA parameters (a.k.a magic numbers..) to ./src/core/system_parameters/GPS_L1_CA.h definition file.
- Tracking blocks now uses DOUBLE values in their outputs.
- Observables and PVT now are separated. PVT and their associated libraries are moved to ./src/algorithms/PVT
- Temporarily disabled the RINEX output (I am working on that!)
- GNSS-SDR screen output now gives extended debug information of the receiver status and events. In the future, this output will be redirected to a log file.
- Bug fixes:
- FILE_SIGNAL_SOURCE now works correctly when the user configures GNSS-SDR to process the entire file.
- GPS_L1_CA_DLL_PLL now computes correctly the PRN start values.
- GPS_L1_CA_DLL_FLL_PLL now computes correctly the PRN start values.
- Several modifications in GPS_L1_CA_Telemetry_Decoder, GPS_L1_CA_Observables, and GPS_L1_CA_PVT modules to fix the GPS position computation.
- New features
- Tracking blocks perform a signal integrity check against NaN outliers before the correlation process.
- Tracking and PVT binary dump options are now documented and we provide MATLAB libraries and sample files to read it. Available in ./utils/matlab" and "./utils/matlab/libs"
- Observables output rate can be configured. This option enables the GPS L1 CA PVT computation at a maximum rate of 1ms.
- GPS_L1_CA_PVT now can perform a moving average Latitude, Longitude, and Altitude output for each of the Observables output. It is configurable using the configuration file.
- Added Google Earth compatible Keyhole Markup Language (KML) output writer class (./src/algorithms/PVT/libs/kml_printer.h and ./src/algorithms/PVT/libs/kml_printer.cc ). You can see the receiver position directly using Google Earth.
- We provide a master configuration file which includes an in-line documentation with all the new (and old) options. It can be found in ./conf/master.conf
