public final class ReferencePointsDisplacement
extends Object

This class provides the model describing the displacements of reference points due to the effect of the solid Earth tides.

Since:

1.2

Description :

Computes the displacement of reference points due to the effect of the solid Earth tides.

Concurrency :

conditionally thread-safe

Concurrency comment :

is thread-safe if the celestial body is too.

Method Summary

Modifier and Type	Method and Description
static Vector3D	poleTidesCorrections(AbsoluteDate date, Vector3D point) Computes the displacement of reference points due to the effect of the pole tides.
static Vector3D	solidEarthTidesCorrections(AbsoluteDate date, Vector3D point, Vector3D sun, Vector3D moon) Computes the displacement of reference points due to the effect of the solid Earth tides.

solidEarthTidesCorrections

public static Vector3D solidEarthTidesCorrections(AbsoluteDate date,
                                                  Vector3D point,
                                                  Vector3D sun,
                                                  Vector3D moon)
                                           throws PatriusException

Computes the displacement of reference points due to the effect of the solid Earth tides.

See IERS conventions 2010, chapter 7, section 7.1.1 "Effects of the solid Earth tides" ftp://tai.bipm.org/iers/conv2010/chapter7/tn36_c7.pdf

Parameters:

date - date of computation in UTC

point - geocentric position of the point (in ITRF Frame)

sun - geocentric position of the sun (in ITRF Frame)

moon - geocentric position of the moon (in ITRF Frame)

Returns:

displacement (in ITRF frame)

Throws:

PatriusException - if some data cannot be read or if some file content is corrupted

poleTidesCorrections

public static Vector3D poleTidesCorrections(AbsoluteDate date,
                                            Vector3D point)
                                     throws PatriusException

Computes the displacement of reference points due to the effect of the pole tides.

See IERS conventions 2010, chapter 7, section 7.1.4 "Rotational deformation due to polar motion: Secular polar motion and the pole tide" ftp://tai.bipm.org/iers/conv2010/chapter7/tn36_c7.pdf

Parameters:

date - date of computation in UTC

point - geocentric position of the point (in ITRF Frame)

Returns:

displacement (in ITRF frame)

Throws:

PatriusException - thrown if pole computation failed
