[amsat-bb] Secondary mission ideas

[Leffke, Zachary]

I also like this idea a lot.
One 'desirement' after having AO-92 up for a bit with our Camera was I wish we had built in a way to time when the shots were taken.  Right now its take a shot, downlink, rinse and repeat (about as simple as it gets).  No onboard storage and it immediately starts taking pictures when kicked into that mode.
So for your #2, if you add in the ability for the uplink command to control when to take a picture (or delay X number of seconds from command receipt) that could be really cool so that the images are not always the same 'regions' of Earth near command stations (especially considering it might only be a single command station if it's a University controlling the bird).  I would also say do something like take 5 pictures, spaced X number of seconds apart, store them, and then downlink them over and over when in high speed/power mode.  All of that control could probably be fit into a single camera uplink command.......in X seconds (or at X time if they have absolute timekeeping), take Y number of pictures (maybe Y in the range of 1-10 or so), spaced Z number of seconds apart......

Here are a couple of ideas.
1) A Funcube type transponder but with an L-Band Uplink.
This would give an easily decoded telemetry downlink for STEM demos etc.
This combined with an L-Band uplink would give a linear transponder to
complement the
FM transponder on AO-92.

2) An on board camera that could be aimed at the earth and store the
resulting picture.
The camera could be triggered by a command station(s) and downloaded (in jpg
format?)
when the transponder was in high power telemetry mode.
This would be a great educational tool.

I just had a super call with a university program flying a mission using
SDRs. We talked about licensing and coordination issues, and discussed ideas
for a secondary two-way mission that they want to do.



What would you like to see, repeater, transponder, BBS, digital voice,
digipeater? Downlink would be on 2m, and would probably be limited to
20-25khz wide. Other ideas? Something new and different? Let's have a
civilized discussion about what they could try, as they seem to be an eager
and capable bunch.
