All Implemented Interfaces:

Serializable, CelestialBody, PVCoordinatesProvider

Deprecated.

@Deprecated
public class MeeusSunStela
extends AbstractCelestialBody

This class implements the Sun ephemerides according to the algorithm of Meeus, it only provides the position. Note that it is not possible to build this Sun from the CelestialBodyFactory.

See Stela's implementation of this model.

This class contains methods to store AbstractCelestialBody.getInertiallyOrientedFrame() to integration frame (CIRF) transform to speed up computation during the integration process. As this transform varies slowly through time, it has been shown it is not necessary to recompute it every time. Warning: these methods should not be used in a stand-alone use (unless you known what you are doing). There are two methods:

• updateTransform(AbsoluteDate, Frame): store transform from AbstractCelestialBody.getInertiallyOrientedFrame() to provided frame at provided date.
• resetTransform(): reset stored transform.

Note that pole information allowing to define inertially-centered frame and rotating frame are defined in IAUPoleFactory since Meeus model does not provide the information.

Constructor Detail

MeeusSunStela

public MeeusSunStela()
              throws OrekitException

Deprecated.

Simple constructor.

Throws:

OrekitException - if data embedded in the library cannot be read

Method Detail

getPVCoordinates

public PVCoordinates getPVCoordinates(AbsoluteDate date,
                                      Frame frame)
                               throws OrekitException

Deprecated.

Description copied from class: AbstractCelestialBody

Get the PVCoordinates of the body in the selected frame.

Specified by:

getPVCoordinates in interface PVCoordinatesProvider

Specified by:

getPVCoordinates in class AbstractCelestialBody

Parameters:

date - current date

frame - the frame where to define the position

Returns:

position/velocity of the body (m and m/s)

Throws:

OrekitException - if position cannot be computed in given frame

updateTransform

public static void updateTransform(AbsoluteDate date,
                                   Frame frame)
                            throws OrekitException

Deprecated.

Update cached transform from FramesFactory.getMOD(boolean) to provided frame. Once called, this transform will always be used when calling getPVCoordinates(AbsoluteDate, Frame) unless a call to resetTransform() has been made.

Parameters:

date - a date

frame - a frame

Throws:

OrekitException - thrown if transformation failed

resetTransform

public static void resetTransform()

Deprecated.

Reset cached transform.
