[amsat-bb] Secondary mission ideas

[Adam Whitney]

I love this idea, Cathryn! I can see a lot of excitement with operators and clubs sending digital postcard images to each other across the globe!

There was quite a lot of participation in sending SSTV images for AO-85 Experimenters’ Wednesday last year, but for that you had to be in the footprint and receive in real-time. This idea takes that to the next level.

Whenever it receives one with proper headers and without error, it stores it. Then on the downlink, it cycles through the last 20 or so, or about however many can be downloaded in an overhead pass. When the 21st picture comes in, it just throws away the oldest image. I suggest using .png formatted graphics with a file size limit of 8192 bytes, something like this?  Enough pixels to be fun, but not so much to get unwieldy.
