How to determine a launch window for the ISS.

How to determine a launch window for the ISS.

I was wondering how to calculate or what equations to use in order to calculate the launch window from KSC to the ISS.  I know that the window lenght is about 5-10 min and that it comes around twice a day about but KSC only uses one.  But I need to know how to calculate what time the window occurs on certain days.  Thank you for your help.

RE: How to determine a launch window for the ISS.

There is a combination of equations for launch windows in Space Mission Analysis and Design by Wertz and Larson and in Fundamentals of Astrodynamics and Applications by Vallado.  If you don't have access to those books, let me know and I may be able to type up a short description of what they have.

Thank you for your reply, I will go to the library and see if they have those books.
