I did an extended notebook on this topic ending up with an animation of the 
earth and a satellite (I called it RSS, Rational Solar Satellite, because it 
revolves exactly twice for every three orbits of the earth and thus the 
animation can run smoothly forever.)

However, it happens that this is an extended example in my DrawGraphics 
package, which I sell for $50, from my web site. You may not be interested 
because of that.

The notebook is actually titled 'Mathematica Notebooks as Pedagogical 
Documents: Derivations of the area swept out by a focal angle in an ellipse' 
and the abstract is:

"This notebook presents an example of the Mathematica style for tutorial and 
student essay notebooks that I advocate. It uses a structured notebook with 
textual discussion integrated with derivations, calculations and graphics, 
active calculation of everything and the generation of embedded knowledge. 
The notebook treats the derivation of an expression for the swept area in an 
ellipse as a function of focal angle. This result was first presented on the 
Internet by David W. Cantrell."
