I seek some suggestions from the experts here.

Hi Andreas,

Thank you very much for reply and check of website. 
Precision for Bird Project I aim is 30 meters. 

Thank you for your help and suggestions are greatly welcomed for CW arrival detection and time measurement.  

Best Regards

Hi Ernest,

the first question for me is, what kind of precision of orbit position/parameters do you want to achieve for your BIRD satellite[0].
I might perhaps help, because I am doing the same thing for my PhD workbut not with GnuRadio and HackRF.

And yes, my approach is DSP heavy as others told here already, and I am working on this for 3 years now (started as a side project). :D

Andreas
