I'm starting such a list for the "Tips for Beginners" segment of next
week's AMSAT News Service bulletin. Yes, please, post your list of
confusing terms so that I can include them.

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.

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 to all of those who contributed their time and talents for this
event. Clearly, a lot of work went into organizing the symposium,
writing the papers, preparing the presentations and compiling the
proceedings. Already looking forward to Minneapolis...

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.

Agree 100%. Thank you all for your hard work. Very interesting and I learned
many things. The pdf handout was very helpful too. It was nice to see the
faces of people I work on the birds.

We talked about the battery situations in both my lessons learned video
and in Q&A, during the last hour of the Symposium program.? The
Symposium program is available for viewing on AMSAT's YouTube channel.?
That's the easiest way for you to hear a more verbose discussion, rather
than an email reply.

GREAT IDEA..................I'll wager I get accused of using more acronyms
than anyone! In my Symposium Paper, I attempted to spell out all the
acronyms I did use, but I'm not sure I did in my presentation and if so,
the slides probably went by too fast for those to be "digested!." So I
went back and resurrected the acronyms I used for the GOLF system design
introduction and have included those in this message as my 'contribution'

Something to add to the list:
MHz? Mega Hertz
mHz? milli Hertz
These are often used interchangeably, where in some cases it is obvious
what is meant, in other case you are left guessing.
The SI system works well when properly used.
You see someone stating that they are on 432.00 mHz when they really
mean 432.00 MHz.
A very big difference.
