Class AbstractVeisProvider

java.lang.Object

fr.cnes.sirius.patrius.frames.transformations.AbstractVeisProvider

All Implemented Interfaces:

TransformProvider, Serializable

Direct Known Subclasses:

G50Provider, VEISProvider

public abstract class AbstractVeisProvider
extends Object
implements TransformProvider

Abstract class for VEISProvider and G50Provider which only differ in UT1/UTC handling. The transformation remains the same, their parent frame is the GTODProvider without EOP correction application.

Since:

4.13

Method Detail

getTransform

public Transform getTransform(AbsoluteDate date)
                       throws PatriusException

Get the transform from GTOD at specified date.

Specified by:

getTransform in interface TransformProvider

Parameters:

date - new value of the date

Returns:

transform at the specified date

Throws:

PatriusException - if data embedded in the library cannot be read

getTransform

public Transform getTransform(AbsoluteDate date,
                              boolean computeSpinDerivatives)
                       throws PatriusException

Get the transform from GTOD at specified date.

Spin derivative, when computed, is always 0.

Specified by:

getTransform in interface TransformProvider

Parameters:

date - new value of the date

computeSpinDerivatives - unused param

Returns:

transform at the specified date

Throws:

PatriusException - if data embedded in the library cannot be read

getTransform

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

Get the Transform corresponding to specified date.

Warning: spin derivative is not computed.

Frames configuration UT1 - TAI is used.

Specified by:

getTransform in interface TransformProvider

Parameters:

date - current date

config - frames configuration to use

Returns:

transform at specified date

Throws:

PatriusException - if transform cannot be computed at given date

getTransform

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

Get the Transform corresponding to specified date.

Spin derivative, when computed, is always 0.

Frames configuration UT1 - TAI is used.

Specified by:

getTransform in interface TransformProvider

Parameters:

date - current date

config - frames configuration to use

computeSpinDerivatives - true if spin derivatives should be computed. If not, spin derivative is set to null

Returns:

transform at specified date

Throws:

PatriusException - if transform cannot be computed at given date

getUT1MinusTAI

protected abstract double getUT1MinusTAI(AbsoluteDate date,
                                         FramesConfiguration config)
                                  throws PatriusException

Returns UT1 - TAI value.

Parameters:

date - a date

config - frames configuration

Returns:

UT1 - TAI value

Throws:

PatriusException - thrown if failed to load data
