Rotating Geodesic Array


Embedded application/x-shockwave-flash

This is 1002 thinsats arranged in a radially-flattened icosahedral geodesic sphere, with V=10 or 9 thinsats between vertices. The array appears to rotate because each thinsat is in a slightly elliptical orbit around the 4 hour circular equatorial orbit. The array is XXX meters across. The size of the array in the orbiting top view is greatly exaggerated, with the sun to the left, looking from the north pole.

The array makes 6 orbits per solar day, while the earth turns once per solar day, appearing as 5 overhead passes from the ground.

At 3 grams per thinsat, this array weighs 30 kg, and has a half-power ground spot size 1km across at 30°N.
