EquinoctialElements Class |
A set of equinoctial orbital elements. This is a nonsingular orbital element set that is often used in operational systems since it is well behaved for small eccentricities and inclinations. The Direction element of the structure indicates whether the orbit is posigrade or retrograde.
All units are SI unless indicated otherwise. For more information see the Units topic.
