Everything I’ve read about this so far leads me to believe these are just continuous tones that only carry information to the extent that they are operating at specific frequencies relative to other. I’m just casually interested in this stuff and my guess is these are probably used to help the receivers in the user terminals correct for doppler shift in the much quieter broadband transmission frequencies. I don’t know if ‘pilot tone’ would be correctly used here but that’s the term that comes to mind.
