We began talkin about a UMSF balloon - and who know what might happen if enough people think about something hard enough, thoroughly enough and long enough. How's about this as a starting point. http://vpizza.org/~jmeehan/balloon/ with http://www.chem.hawaii.edu/uham/part101.html as an important regulatory start point (I'm going to look up the UK regs for this as well) http://www.srcf.ucam.org/~cuspaceflight/nova1launch.html is also very impressive - all done in the UK This http://www.makezine.com/blog/archive/2007/...video_podc.html is particularly impressive - I like the multiple-cameras slant. Anyway - thought I'd get a thread going - this is an idea I like too much to let it gather dust in a corner - the one thing that I think would be nice to achieve is self-portraiture of some sort - think Beagle 2's WAM etc....perhaps in a corner of the FOV of one of/the imaging system. What sort of limit's should we set ourselves? 1kg 10x10x20cm? (sort of 2U Cubesat-on-a-diet budget) Doug |

OK a few simulations of camera coverage.
Two cameras, one landscape pointed horizontally, one portrait, pointed 45 degrees down both normal 35mm field of view. Take one image with each and here is the coverage on a 360x180 degree equirectangular projection. Rotate and swing to the payload, 30 degrees looks about right from a lot of images I've seen from other attempts. Take 25 images per camera (one every 15 seconds for ~6 minutes say) and you'd be unlucky not to get a 360 and most terrain should be covered twice. Coverage tends to improve (less likely to get that jagged line of missing data) if you don't have the cameras going off simultaneously (which should also be easier to implement ) -------------------- |
