*
* \detail The fundamental plane is the satellite's orbit, and the origin is at the 
* center of the Earth. The P axis points towards perigee, and the Q axis is \f$90^{\circ}\f$
* from the P axis in the direction of satellite motion. The W axis is then normal to the orbit. 
* The PQW system always maintains an orientation towards perigee and is therefore best
* suited for robits with a well-defined eccentricity. (Vallado, pg 41)
