Thank you for the reference.
DH, I do realize it is a huge field and should have been more clear in my post. I am just looking for a good introduction to the field and not asking for everything to be summarized in one book.
I am a math grad student who has really got interested in spacecraft control and navigation.
Like a lot of people, I have been playing too much ksp and gotten interested in the mathematics of spacecraft navigation and control. For fun, I derived some basic motion and control equations...
