Class MODProvider

java.lang.Object

fr.cnes.sirius.patrius.frames.transformations.MODProvider

All Implemented Interfaces:

TransformProvider, Serializable

public final class MODProvider
extends Object
implements TransformProvider

Mean Equator, Mean Equinox Frame.

This frame handles precession effects according to the IAU-76 model (Lieske).

Its parent frame is the GCRF frame.

It is sometimes called Mean of Date (MoD) frame.
