Returns:

the frame name as it appeared in the file (B).

getReferenceFrame

Frame getReferenceFrame()

Get the reference frame from which attitude is defined.

Returns:

the reference frame from which attitude is defined

getAttitudeDirection

String getAttitudeDirection()

Get the rotation direction of the attitude.
