The problems of spacestation attitude control are considered. These problems are still quite interesting and do exist. From a practical point of view the interest in such problems is supported by increasingly more general statements. The spacestation is considered with variable structure. This means that there are several spacestation units and these units can be added to the main station or deleted from it. Under these operations the mass, the centre of mass, and the ellipsoid of inertia are changed. From a theoretical point of view, these problems remain important because the majority of the known solutions are obtained with the traditional constraints on the class of motions. The principal axes of the ellipsoid of inertia are frequently assumed to coincide with the axes of the body-axis coordinate system, but this is not the case of spacestation with variable structure. Therefore, there are two problems. First one should recalculate the matrix of the moments of inertia after each change of spacestation structure. Secondly one should solve the reorientation problem in general case. The software is presented. This software can help to solve these two problems. Using this software one can create several space units and assemble a spacestation. Mathematical support of this assembly recalculates the matrix of the moments of inertia automatically. Then the software designs the control for reorientation problem. One of design methods is based on the concept of the inverse problem of dynamics. In this approach, one can design the control in the case of any matrix of the moments of inertia. Finally, the software animates the rotation of spacestation.
