- 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

How to set up the compilation environment for Ubuntu 9.10 and 10.04
|
|
|
|
- Download GNU Radio 3.3.0 from ftp://ftp.gnu.org/gnu/gnuradio
|
|
- Compile and install following the instructions at http://gnuradio.org/redmine/wiki/1/UbuntuInstall
|
|
- Install bjam with the command 'sudo apt-get install bjam'
|
|
- Install Boost.Build with the command 'sudo apt-get install boost-build'
|
|
- Add the system variable GNURADIO_330_ROOT with the location of the sources of gnuradio-3.3.0
|
|
- Download gtest-1.4.0.tar.gz from http://code.google.com/p/googletest.
|
|
- Unpack gtest-1.4.0.tar.gz into some folder.
|
|
- From the folder containing gtest build the libraries and install them:
|
|
- GTEST$ ./configure
|
|
- GTEST$ make
|
|
- GTEST$ make check
|
|
- GTEST$ sudo make install
|
|
- Add the following line to your .bashrc:
|
|
- export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/lib
|
|
- Download glog-0.3.0.tar.gz from http://code.google.com/p/google-glog.
|
|
- Unpack glog-0.3.0.tar.gz into some folder.
|
|
- From the folder containing glog, build and install the libraries:
|
|
- GLOG$ ./configure
|
|
- GLOG$ make
|
|
- GLOG$ sudo make install
|
|
NOTE: THE LOG FILES ARE STORED BY DEFAULT /TMP/
|
|
- Download gflags-1.3.tar.gz from http://code.google.com/p/google-gflags.
|
|
- Unpack gflags-1.3.tar.gz into some folder.
|
|
- From the folder containing gflags, build the libraries and install them:
|
|
- GFLAGS$ ./configure
|
|
- GFLAGS$ make
|
|
- GFLAGS$ sudo make install
|
|
|
|
- (28/11/2011) Download, compile, and install the Armadillo linear algebra library
|
|
1. Download the latest stable version from http://arma.sourceforge.net/
|
|
2. Unpack it
|
|
3. Open a shell, change into the directory that was
|
|
created by unpacking the armadillo archive, and type the following
|
|
commands:
|
|
cmake .
|
|
make
|
|
The full stop separated from "cmake" by a space is important.
|
|
CMake will figure out what other libraries are currently installed
|
|
and will modify Armadillo's configuration correspondingly.
|
|
CMake will also generate a run-time armadillo library, which is a
|
|
combined alias for all the relevant libraries present on your system
|
|
(eg. BLAS, LAPACK and ATLAS).
|
|
4. Install the library
|
|
sudo make install
|
|
|
|
(11/12/2010) GSL AND CBLAS ARITHMETIC
|
|
|
|
In order to compile the arithmetic tests, the GNU Scientific Library (GSL) library package is needed.
|
|
Install the ubuntu package with:
|
|
|
|
sudo apt-get install libgsl0ldbl
|
|
|
|
|
|
To build the project type call bjam from the project root folder.
|
|
|
|
PROFILING
|
|
|
|
In order to do profiling, you'll have to install google-perftools library.
|
|
- Download google-perftools-1.5.tar.gz from http://code.google.com/p/google-perftools.
|
|
- Unpack google-perftools-1.5.tar.gz into some folder.
|
|
- From the folder containing google-perftools, build and install the libraries:
|
|
- PERFTOOLS$ ./configure
|
|
- PERFTOOLS$ make
|
|
- PERFTOOLS$ sudo make install
|
|
|
|
Once google-perftools is installed, you can use the script "profiler" which is placed
|
|
in the root folder of GNSS-SDR sources. The script must be run as root since it makes use
|
|
of "nice". The result of the profiling are two files, mercurio.cpu.prof and mercurio.head.prof.0001.heap,
|
|
that contain the results for CPU and HEAP profiling. You can use google-perftools' script pprof
|
|
to analyze the recorded data.
|
|
|
|
(Sample of .bashrc configuration)
|
|
|
|
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/lib
|
|
export GNURADIO_330_ROOT=/home/gnss/sdr/gnuradio-3.3.0
