Well that shut em all up big time...

There's a solution manual for that, I'm sure.

I tend not to deal with orbital coordinates, except for feeding TLEs to
whichever app I'm using at the moment. (Currently, DroidSat.
However, I still rank STSPLUS very high, though the author is long
gone.)

My small number of books on orbital mechanics are in storage, so I
wouldn't be able to do better than look at Wikipedia, and try to parrot
it back.

There are still a couple of people here who have done orbital
mechanics, IIRC, but perhaps not since school.
