public class SynodicFrame
extends Frame

Synodic frame. A synodic frame is a frame aligned on a LocalOrbitalFrame and translated by a proportional distance along the axis defined by the 2 centers (LOF center and LOF parent center). This kind of frame is well suited for the 3rd body problem, for which the classical synodic frame is:

LOF frame is of type LOFType.QSW centered around 2nd body and normalized center position is defined using bodies mass ratio (in [0, 1]). 0 means the synodic frame is centered around the main body, 1 means the synodic frame is centered around the LOF (i.e. the second body in case of three body problem).

Constructor Detail

SynodicFrame

public SynodicFrame(LocalOrbitalFrame parentLOF,
                    String name,
                    double normalizedCenterPosition)

Constructor.

Example: LOF of type LOFType.QSW centered around 2nd body and normalizedCenterPosition using bodies mass ratio will produce the classical synodic frame for three body problem.

Parameters:

parentLOF - parent frame of type LocalOrbitalFrame (must be non-null)

name - name of the frame

normalizedCenterPosition - normalized center position: 1 means this frame is equal to provided LOF (i.e. centered on the 2nd body), 0 means this frame is translated to the parent frame center (i.e. centered on the main body)

Throws:

IllegalArgumentException - if the parent frame is null
