/*! \brief NTW Satellite Coordinate System
*
* Detailed Description. The primary axis lies in the orbital plane, normal to the velocity
* vector. The T axis is tangential to the orbit, and the W axis is normal to the orbital plane.
* In-track: deviations along the T axis.
* Used mainly to analyze drag effects on the orbit because drag always acts along the velocity
* vector. Also referred to as the Frenet System. (Vallado, pg. 43-44)
