Attitude is the orientation of an aircraft, ship, or spacecraft – its yaw, roll, and pitch – with respect to a particular frame of reference. In the case of a spacecraft in Earth orbit, this frame of reference is usually fixed relative to Earth. However, interplanetary space probes often use bright stars as a frame of reference.
