Python block that updates a GNU Radio variable with the absolute frequency as provided by Gpredict. This allows for Doppler shift corrected reception of satellite signals. Example gnuradio-companion flowgraphs are installed with the package and can be found in: - (Linux/macOS) $CONDA_PREFIX/share/gnuradio/examples/gpredict_doppler - (Windows) %CONDA_PREFIX%\share\gnuradio\examples\gpredict_doppler
