keplerianOrbit

class KeplerianOrbit

#include <keplerianOrbit.h>

The KeplerianOrbit class represents an elliptical orbit and provides a coherent set of common outputs such as position and velocity, orbital period, semi-parameter, etc. It uses the utility orbitalMotion to do orbital element to position and velocity conversion.

Public Functions

KeplerianOrbit()

This constructor initialized to an arbitrary orbit

KeplerianOrbit(classicElements oe, GravBodyData *planet)

The constructor requires orbital elements and a planet

KeplerianOrbit(const KeplerianOrbit &orig)

The copy constructor works with python copy

This method populates all outputs from orbital elements coherently if any of the classical orbital elements are changed

void change_f()

This method only changes the outputs dependent on true anomaly so that one orbit may be queried at various points along the orbit
