[amsat-bb] Re: Path to HEO

[Nick Pugh]

If the solar panels are on 1 end that could be the back side of a patch
antenna or reflectors for a Yagi. A 3U gives us about 12 inches in one
plane. We will have reaction wheels to do pointing. Both Pumpkin and ISSIS
say they have flight heritage on > 50 watt panels. EaLanta has rides to 600
KM and we will have to deal with MR Van Allen when we get there. 

This is a great topic at the attitude adjustment session with cold 807's at
Dayton

Where do the gain antennas go on a 10x10x30cm HEO?

some heavy duty ($$) radiation tolerant components to survive a few years
trip through the radiation belts as well as the final high orbit?
