[Discuss-gnuradio] DOPPLER SHIFT

[ERNEST MATEY]

Hi All,

I am trying to track Satellite for CW  signal receiving and analysis on my GNURadio.  

I know I need some tracking with Doppler shift. 

What is the best way to do this?

Now, I have GPredict installed hoping to use it. 

I have added the GPredict doppler block to my GRC library blocks and added the block to my flow graph hoping to get Doppler shift from my engaged GPredict 

I have set my Ports correctly but I have an error.

ImportError: No module named gpredict. 

What can I do?  

I also learnt I can control my receiver ( Hackrf) frequency dir‎ectly from Gpredict using Hamlib. Will this work?  

I tried to install Hamlib but installation says will delete some GRC files before Hamlib will work‎. I don't want to temper with my healthy running GRC 

What can I do for my Doppler Shift?

I am on Ubuntu 14 and I am very new to these thing

Thank you for sharing your expertise.

God Bless you!
