Gqrx and Gnuradio Doppler correction

Hi folks,
I am trying to use gpredict with gqrqx and gnuradio to decode digital satellites.
I am still at the beginner and cannot understand how to do.
Actually i am moving the frequency manually but i would like to how to do for doing it in automatic.
Please any advice how to set the programs?

You can do it in this way… i’m doing it with that step by step and it works.

Let me know if i can help you with that, if you have problems

Thanks it worked.
Now i have to understand how to make gnuradio decoding the satellites.
Can you help me maybe off the forum as it is only for gpredict???
Thanks once more

i don t know how do that,if you want to try and share the results, it would be great…

Maybe you can see the GNU Radio module from Daniel Estevez (

Please i need an help with gpredict and GQRX.
I have se the programs and they communicate with no problems during a pas but if i have a pass of satellite that are in FM mode and the next satellite i want to track is in SSB, than the frequencies of uplink and downlink changes to the correct frequencies but the mode does not change.They rest in FM so i need to change it manually.
Please where am i doing wrong?

Gpredict only controls the frequency, it does not set the mode. There is an open feature request to implement mode setting.
