I guess sometimes it depends to what extent you are interested in the internals of the satellite. I certainly meant to define esoteric terms in my papers and I think Eric did too, but we might have missed it and I apologize if so. IHU is Internal Housekeeping Unit, which means the on-board computer. I think that term comes from way back in history. Maybe someone else knows--perhaps when people did not trust a *computer* to be on a spacecraft.
That term is kind of general for AMSAT spacecraft, but stuff like "CIU" (Control Interface Unit) is very specific to the design of the Golf spacecraft. (The CIU is "where all the wires come together" :-) from the AMSAT part of the spacecraft to the external test environment, the solar panels, the ADAC [ha! Attitude Determination and Control] unit, etc.)
Feel free to ask as you come across stuff; hopefully someone will answer and Mark will add it to his own list. But don't forget too that a search engine can help too. Searching for CIU AMSAT got me the actual words for CIU that I could not remember for sure.

Thanks, Burns and Bruce. Actually, I only wrote down "IHU", but noticed that each section of the GOLF-TEE description showed an abbreviation and was not able to write each down before the next phase of the program went on.
There are so many terms within the engineering, software and orbital elements to keep up with. I was looking for a list.

It's a good idea, Gerald--I don't remember such a list, but it could have been. Could you start the ball rolling by sending out the list of terms that you already wrote down which you did not know? Sometimes it's hard for those of us steeped in them to realize what is unknown.

Abbreviations and acronyms are a real headache for me from time to time. I was told that in the past the AMSAT Journal sometimes printed a table of abbreviations used frequently. I have some Journals from Sept/Oct 2019 to current issue, but do not include such table.
Is there such table available and where may I find it, please?
I listen to Saturday's Symposium and was overwhelmed with the terms used. I wrote down and looked up later a few of the terms. I realize that it probably take time to learn, but a list or table would help!
Thanks, and 73 to all.
