Method Detail

getPVCoordinates

TimeStampedFieldPVCoordinates<T> getPVCoordinates(FieldAbsoluteDate<T> date,
                                                  Frame frame)
                                           throws OrekitException

Get the FieldPVCoordinates 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
