Constructor Detail

ConstantPVCoordinatesProvider

public ConstantPVCoordinatesProvider(PVCoordinates coordinatesIn,
                                     Frame frameIn)

Simple constructor.

Parameters:

coordinatesIn - the pv coordinates to store

frameIn - the frame of used for computation

ConstantPVCoordinatesProvider

public ConstantPVCoordinatesProvider(Vector3D positionIn,
                                     Frame frameIn)

Builds an instance from the position vector only. The object is supposed to be motionless in the computation frame.

Parameters:

positionIn - the position of the object

frameIn - the frame of computation

Method Detail

getPVCoordinates

public PVCoordinates getPVCoordinates(AbsoluteDate date,
                                      Frame frameIn)
                               throws PatriusException

Description copied from interface: PVCoordinatesProvider

Get the PVCoordinates of the body in the selected frame.

Specified by:

getPVCoordinates in interface PVCoordinatesProvider

Parameters:

date - current date

frameIn - the frame where to define the position

Returns:

position/velocity of the body (m and m/s)

Throws:

PatriusException - if position cannot be computed in given frame

getNativeFrame

public Frame getNativeFrame(AbsoluteDate date)
                     throws PatriusException

Description copied from interface: PVCoordinatesProvider

Get the native frame, i.e. the raw frame in which PVCoordinates are expressed before transformation to user output frame.

Specified by:

getNativeFrame in interface PVCoordinatesProvider

Parameters:

date - a date

Returns:

the native frame

Throws:

PatriusException - thrown if native frame is undefined or unknown
