I am going to make notes (and code) available here to help cryosphere investigators use GPS reflections (sometimes called GPS Interferometric Reflectometry). Eventually I will extend these notes to include sea level measurements.
I will only talk about GPS here, but most everything I talk about can be extended to GNSS.

This GPS reflections method is being used to measure snow accumulation every day at four sites in Greenland:
