Hi, I've recently needed to correct some satellite signals for Doppler shift. I found that there was no easy way to do this yet - so I've created a small block that takes the Doppler shift information from Gpredict and populates a variable in GNU Radio with it any time the doppler shift changes. It allows for easy shift correction by mixing the signal, I've added an example flowgraph to do so as well.
You can find it here: https://github.com/wnagele/gr-gpredict-doppler Let me know what you think. Cheers, Wolfgang _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
