Specifically, probably not mostly - though the Escobal book does contain some elements of geocentric orbits, and of course, the physics is the same (though the devil is in the details....). There are some other astrodynamics books that do deal with geocentric motion in more detail. I think Taff's book as well as Thomson include significant treatment of geocentric orbits. Does anyone know of a webpage or FAQ that discusses these items in more detail? We may have the bits and pieces of it at least on the SEESAT-L webpages, I bet. > There are several programs for SATELLITE orbit determinations, eg.
