Hi Andrew, Shameless plug, but you can take a look at this repo https://gitlab.com/phorvath/smogcli2 to record samples with RTL-SDR and Raspberry PI. It is developed for the ATL-1 and SMOG-P satellites. It is a standalone application, samples at 1.6 or 2.0 maps, tracks the location of the satellite and starts recording if the elevation is above -2 degrees. When it is recording it compensates for Doppler and then downsamples to 50 ksps (or 62.2 ksps). You can process your recordings with gr-satellites or a GNURadio flow graph..
