Class IERS2010LibrationCorrection

java.lang.Object

fr.cnes.sirius.patrius.frames.configuration.libration.IERS2010LibrationCorrection

All Implemented Interfaces:

LibrationCorrectionModel, Serializable

public class IERS2010LibrationCorrection
extends Object
implements LibrationCorrectionModel

This class computes the diurnal lunisolar effect. It is a java translation of the fortran subroutine PM_GRAVI (provided by CNES and from IERS conventions, see chapter 5, tables 5.1a and 5.2a).

public IERS2010LibrationCorrection()

Simple constructor.

Method Detail

getPoleCorrection

public final PoleCorrection getPoleCorrection(AbsoluteDate date)
                                       throws PatriusException

This method provides the diurnal lunisolar effect on polar motion in time domain. The computed corrections should be added to EOP values. The fundamental lunisolar arguments are those of Simon and al.

Specified by:

getPoleCorrection in interface LibrationCorrectionModel

Parameters:

date - date at which the correction is desired

Returns:

pole correction

Throws:

PatriusException - when an Orekit error occurs

getUT1Correction

public final double getUT1Correction(AbsoluteDate date)

Get the dUT1 value. The correction is due to diurnal lunisolar effect.

Specified by:

getUT1Correction in interface LibrationCorrectionModel

Parameters:

date - date at which the value is desired

Returns:

dUT1 in seconds

getOrigin

public FrameConvention getOrigin()

Get IERS model origin.

Specified by:

getOrigin in interface LibrationCorrectionModel

Returns:

IERS model origin
