public interface PVCoordinatesProvider

Interface for PV coordinates providers.

Author:

Veronique Pommier

The PV coordinates provider interface can be used by any class used for position/velocity computation, for example celestial bodies or spacecraft position/velocity propagators, and many others...

Modifier and Type	Method and Description
TimeStampedPVCoordinates	getPVCoordinates(AbsoluteDate date, Frame frame) Get the PVCoordinates of the body in the selected frame.

Method Detail

getPVCoordinates

TimeStampedPVCoordinates getPVCoordinates(AbsoluteDate date,
                                          Frame frame)
                                   throws OrekitException

Get the PVCoordinates of the body in the selected frame.

Parameters:

date - current date

frame - the frame where to define the position

Returns:

time-stamped position/velocity of the body (m and m/s)

Throws:

OrekitException - if position cannot be computed in given frame
