Doppler Shift Calculation

Hi,

I recently received a pass from a LEO satellite, and I am interested in collecting information on how
the doppler shift of this measured (IQ) signal is changing over time. Is there any software/toolkits
that can help calculate the doppler shift over the time of the pass given the IQ signal? To clarify, I’m not interested in doppler shift compensation during the collection of the satellite signal.

Have a look at https://celestrak.com/software/tskelso-sw.php and then especially the SGP4/SDP4 information.
