Abstract:

Location of spacecraft is given generally by two coordinates, orbital and attitude. Expressions of a constant vector in these two coordinates are studied. Transformation matrix of Euler rotation of one coordinate is obtained in the other coordinate. The three Euler angles of the spacecraft rotating about its mass point are identified with the expressions of two constant vectors in these two coordinates. The above method has been used in practice.

Key words: Euler rotation, attitude identification
