attitude 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 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.
