Re: Perifocal conversion to geocentric

Sorry for the double post, but I did end up solving the problem. I
would like to explain what I did, in case anyone encounters a similar
problem.

As I stated above, I actually had very little to start with. However,
I could break down the starting position (radius) be longitude,
latitude, and the radius of the Earth. As eccentricity lies along the
apse line in the perifocal frame, then the unit vector for radius
multiplied by the eccentricity magnitude yields the eccentricity
vector. Also, as the specific angular momentum is perpindicular to the
perifocal frame, I took the cross product of two vectors that lied
within the perifocal frame, namely the two perigees for my apse line
rotation. I multiplied this unit vector defining the direction of the
specific angular momentum by the magnitude of my specific angular
momentum. With these, I could then proceed to solve for my classical
orbital elements, from which I could completely describe both orbits
before and after the apse line rotation.

Thank you again for your help.
