I took an action at the last meeting to document basic BBS operations. I put some thoughts in the attached document. This is in Open Office format. For those without Open Office I attached a pdf.
I will happily put this in git if someone points me to the git repository.
All thoughts / comments welcome. This is mostly a brain dump of how things work "today" with some thoughts about the future.

Thanks Chris! I especially like the discussion about purpose. One research feature that occurs to me is this: Imagine a system on the Lunar Gateway (or the moon or an earth-crossing asteroid or...). We might want to use this delay-tolerant protocol to download data like pictures taken at the site of the system itself. In other words, the experiment part would be how to autonomously create files (e.g. take a picture under these circumstances) and make them available for delay-tolerant download. Similarly, one might have an uplink form that would be a command to take a picture or whatever.
This is far from Bill's expectation (which I totally agree with) to make the first version essentially replicate FalconSat-3 to get our feet wet. However, thinking about a long term goal is a great idea.

Most BBS also allow immediate digipeating for those that wanted a real time QSO. This is/was commandable on and off on 51 and FS-3. A dedicated receiver could also snoop and collect worldwide APRS beacons to a BBS file.
Another important use of the BBS is for Whole Orbit Data, both from spacecraft systems and potential experiments. My assertions that this would greatly simplify many cubesat telemetry issues have mostly fell upon deaf ears, since it’s not an off the shelf solution for the typical university cubesat. We could make it one. It works particularly well with an imaging system to get complete images over multiple passes or from multiple stations.

Oh, I forgot to mention, in many cases, BBS satellites also had a bent pipe mode. UO-14 and AO-51 come to mind, as does FS-3 although it ceased working by the time we got the keys and tried it.

Great points Drew, which I will incorporate into the document.
