Wednesday's launch of a large batch of satellites seems an opportunity to try the Doppler shift method of matching a satellite to a set of keps.
In reading a few blogs and posts it seems the method is to use an SDR and GNURadio tools to determine the time of TCA for a downlink signal. Then use a tracking program to provide the TCA time for several sets of keps. And finally to match the observed/calculated TCA with one set of keps. Can anyone provide a pointer to a GNURadio flow diagram that includes a tool to calculate TCA time from the signal received during a pass? I'm pretty new to GNURadio so finding such resources is still a bit of a mystery for me.
