                                                                              Frame frame)

Get the position of the body in the selected frame.

Parameters:

date - current date

frame - the frame where to define the position

Returns:

position of the body (m and)

Since:

12.0

getPVCoordinates

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