astro.conversions#

A set of conversions used to move between different methods of parameterizing and determining an orbit.

classical_2_state

Converts the classical orbital elements (where true anomaly is the fast parameter) into inertial position and velocity.

classical_2_state_p

Parabolic version of classical_2_state() which takes in the semi-latus rectum instead of the semi-major axis.

state_2_classical

Converts inertial position and velocity into the classical orbital elements (where true anomaly is the fast parameter).

state_2_classical_p

Parabolic version of state_2_classical() which takes in the semi-latus rectum instead of the semi-major axis.

equinoctial_2_state

Converts the modified equinoctial orbital elements (where true latitude is the fast parameter) into inertial position and velocity.

classical_2_equinoctial

Converts the classical orbital elements into the modified equinoctial orbital elements.

equinoctial_2_classical

Converts the modified equinoctial orbital elements to the classical orbital elements.
