Class ITRFProvider

java.lang.Object

fr.cnes.sirius.patrius.frames.transformations.ITRFProvider

All Implemented Interfaces:

TransformProvider, Serializable

public final class ITRFProvider
extends Object
implements TransformProvider

International Terrestrial Reference Frame.

Handles pole motion effects and depends on TIRFProvider, its parent frame.

Spin derivative is never computed and is either 0 or null. No analytical formula is available for spin derivative since data only provide pole correction without derivatives. Spin is also 0. Spin is also 0.

Frames configuration polar motion and S' is used.

Method Detail

getTransform

public Transform getTransform(AbsoluteDate date,
                              FramesConfiguration config)
                       throws PatriusException

Get the transform from TIRF 2000 at specified date.

The update considers the pole motion from IERS data.

Frames configuration polar motion and S' is used.

Specified by:

getTransform in interface TransformProvider

Parameters:

date - new value of the date

config - frames configuration to use

Returns:

transform at the specified date

Throws:

PatriusException - if the nutation model data embedded in the library cannot be read
