Method Detail

getReferenceFrame

public ReferenceFrame getReferenceFrame()

Return the identifier of the object's reference frame.

Returns:

the ReferenceFrame identifier

getCoordinate

public void getCoordinate(double timeValue,
                          Spherical spherical)

Calculate the position of the object referenced to it's parent reference frame at the specified time and initialize the argument Spherical object with the position coordinate.

Parameters:

timeValue - the time instant for calculating the object's position

spherical - the object to initialize with the object's position coordinate

getCoordinate
