You explain it very well, and I think Kevin is asking for the same
feature. As far as I understand, Greg has this implemented in
COSATRAK.

In principle you could select any point along the plane and track
that. One good option would be the point along the plane with the
highest elevation, but a better option would be to select the point
where the satellite would be expected to be brightest. The latter
depends on the range and phase angle as explained in this post:
http://www.satobs.org/seesat/Apr-2001/0313.html This obviously does
not take into account reflections from surfaces, in fact it assumes
the satellite is a simple sphere, but this is the best guess in
absence of other information.

Regards,
