Application of nonclassical quaternions and pentanions of helf-rotations in problems of inertial orientation

The article considers the nonclassical quaternions and pentanions of helf-rotations of solid body and their application in problems of control and orientation of moving objects. In contrast to classical rationed Hamiltonian quaternions of complete rotations the nonclassical quaternions of helf-rotations may be null, they have variable rates, depending on the angle of Euler finite rotation.
