Constructor Detail

AbstractRadiationForceModel

protected AbstractRadiationForceModel(ExtendedPVCoordinatesProvider sun,
                                      double equatorialRadius)

Constructor.

Parameters:

sun - Sun model

equatorialRadius - spherical shape model (for umbra/penumbra computation)

Method Detail

dependsOnPositionOnly

public boolean dependsOnPositionOnly()

Check if force models depends on position only.

Returns:

true if force model depends on position only, false if it depends on velocity, either directly or due to a dependency on attitude

getEventsDetectors

public Stream<EventDetector> getEventsDetectors()

Get the discrete events related to the model.

Returns:

stream of events detectors

getFieldEventsDetectors

public <T extends RealFieldElement<T>> Stream<FieldEventDetector<T>> getFieldEventsDetectors(Field<T> field)

Get the discrete events related to the model.

Type Parameters:

T - extends RealFieldElement<T>

Parameters:

field - field to which the state belongs

Returns:

stream of events detectors

getEclipseAngles

protected double[] getEclipseAngles(Vector3D sunPosition,
                                    Vector3D position)

Get the useful angles for eclipse computation.

Parameters:

sunPosition - Sun position in the selected frame

position - the satellite's position in the selected frame

Returns:

the 3 angles {(satCentral, satSun), Central body apparent radius, Sun apparent radius}

getEclipseAngles

protected <T extends RealFieldElement<T>> T[] getEclipseAngles(FieldVector3D<T> sunPosition,
                                                               FieldVector3D<T> position)

Get the useful angles for eclipse computation.

Type Parameters:

T - extends RealFieldElement

Parameters:

sunPosition - Sun position in the selected frame

position - the satellite's position in the selected frame.

Returns:

the 3 angles {(satCentral, satSun), Central body apparent radius, Sun apparent radius}
