gr-satnogs: SatNOGS GNU Radio Out-Of-Tree Module

gr-satnogs is an out-of-tree GNU Radio module that provides all the necessary tools for decoding signals from various scientific and academic sattelites.



  • GNU Radio ( > 3.7.7 )
  • CMake ( > 3.1)
  • G++ (with C++11 support)
  • VOLK
  • libogg
  • libvorbis
  • libpng
  • libpng++
  • git


  • gr-osmocom (for using the flowgraphs with real SDR hardware)
  • libnova (for building the debug blocks)
  • libfec (it will automatically installed if not present)


  1. git clone
  2. cd gr-satnogs
  3. mkdir build
  4. cmake ..
  5. make
  6. sudo make install

If this is the first time you are building the gr-satnogs module run sudo ldconfig


By default, the SatNOGS module will use the default installation prefix. This highly depends on the Linux distribution. You can use the CMAKE_INSTALL_PREFIX variable to alter the default installation path. E.g:


Also, by default the build system enables a set of blocks used for debugging during the development. The enable/disable switch is controled through the INCLUDE_DEBUG_BLOCKS boolean variable. If for example, you want to disable the debugging blocks, the CMake command would be:


Another common control option is the library sugffix of the Linux distribution. There are distributions like Fedora, openSUSE, e.t.c that the their 64-bit version use the lib64 folder to store the 64-bit versions of their dynamic libraries. On the other hand, distributions like Ubuntu do the exact opposite. They use lib directory for the libraries of the native architecture and place the 32-bit versions on the lib32 directory. In any case the correct library directory suffix can be specified with the LIB_SUFFIX variable. For example:


will install the libraries at the /usr/lib64 directory.
