The foreign Astronautical Federation is the single specialist society within the box of aerospace engineering and Sciences which brings jointly experts of all nations drawn to the exploration and peaceable exploitation of house. At its annual Congresses a great number of invited and/or rigorously chosen con­ tributed papers are awarded which disguise a wide selection of subject matters and are disbursed over a couple of classes, each being geared up by means of prime scientists who later chair the consultation itself. every year the choice of particular subject matters to be handled. is dictated both through major new growth accomplished in a few sectors or via new advancements and developments that are vulnerable to impression considerably the pursuits towards which house learn and/or program of house know-how should be orientated within the quick destiny. A moment rigorous screening, played with assistance from the consultation Chairmen and conducted in keeping with an analogous standards identifies ultimately the papers that are released within the lawsuits. the end result of all this can be trustworthy and authoritative info as to the particular prestige and destiny tendencies of area actions, either from the study perspective and from the viewpoint of u~ilization and/or application.

The ellipse planes are not tangent to the sphere except on the poles and the equator. / EXACT ( SI~IULAT I N) ANALYTIC Fig. 4. Locus of an inertial force vector. On the poles, the ellipses are the largest, while on the equator, they become straight lines. Generally, as the position approaches the equator, the ellipses become slender, as in the case of dual-spin, and smaller. There are two main differences between Ad and As; the first is that the ellipse planes are tangent to the sphere for dual-spin, while they are not always tangent to the sphere for single-spin.

Dt 2 = ~ + 2(w . x ~) +Wx ~ +w x (w x ~). (3) Here, we define a vector A, by Equation (4). A == wx ~ +w x (w x (4) ~). Rotor ( Symmetric) )' Fig. I. Dual-spin system. Substituting A, ~ = UA and ~ = UA into Equation (3), we have where (5) In order to solve Equation (5), it is necessary to determine the vector A. Generally, m is very small comparing with the satellite mass, therefore the Euler Equation (I) can be solved approximately. Since the stator is controlled to be non-spinning, wz=O. Then Equation (I) becomes (Ix (Ill + I~)wx + Icwcwy = 0 + I~)wy - fcwcwx = 0 Icwc - (Ix - Iy)wxw y = O.
