[amsat-bb] ISS SOlar arrays

[Bob Bruninga <bruninga@xxxxxxxx>]

It appears to me in all photos that the solar arrays on ISS only have one
degree of freedom.  So to point at the sun, not only do the arrays have to
tilt, but then the pointing vector of the axis of the whole ISS has to
also then rotate once per orbit "horizontally" so that the arrays remain
pointed at the sun.

Thus, the "pointing" vector of the axis of the space station body is
always  changing....  The only thing that is constant is that the "down"
side is always down?

I may not be using the right terms, but is that about right?
