Attitude expression suitable for directing an axis of a spacecraft to a specified direction is discussed. An expression that features no singularity between attitude parameters and a direction cosine matrix is introduced. Both new and former expressions are summarized from a unified viewpoint and the kinematical relations are derived. Then, the application of the proposed expression to pointing control of a spacecraft and to utilization of gravity-gradient torque is investigated. In pointing control, the proposed expression provides simple PD-type control to stabilize an axis direction. In utilization of gravity-gradient torque, it derives a simple and exact attitude that achieves an arbitrary gravity-gradient torque. The validity of the expression is shown by numerical examples.
