Method Detail

getTransform

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

Get the transform from GCRF to Earth-Moon barycenter frame at the specified date.

Specified by:

getTransform in interface TransformProvider

Parameters:

date - new value of the date

config - frames configuration to use

Returns:

transform at the specified date library cannot be read

Throws:

PatriusException - if the JPL ephemeris data cannot be retrieved

getTransform

public Transform getTransform(AbsoluteDate date)
                       throws PatriusException

Specified by:

getTransform in interface TransformProvider

Parameters:

date - new value of the date

Returns:

transform at the specified date

Throws:

PatriusException - if the JPL ephemeris data cannot be retrieved

getTransform

public Transform getTransform(AbsoluteDate date,
                              boolean computeSpinDerivatives)
