State lupnt::CartToClassical(const State &rv, Real GM)

Convert Cartesian state to classical orbital elements.

Convert a Cartesian position-velocity state to classical orbital elements.

Parameters:

• rv – Cartesian state [km, km/s]

• GM – Gravitational parameter [km^3/s^2]

• rv – Cartesian state in the same distance/time units as GM.

• GM – Gravitational parameter consistent with the state units.

Returns:

Returns:

Classical orbital element state [a, e, i, RAAN, arg_periapsis, anomaly].
