Agreed. Personally, I am not asking for the specifics for any satellite,
only in general how security of the command uplink is obtained.
Unlike other contributors I don't think "NONE OF MY BUSINESS"
applies in ham radio. So if anyone can share any information
on this topic, or suggest some reading, I would be most interested.
(I am simply curious.)
