The structure of a three-degree-of-freedom gyrostabilizer (TGS) that makes it possible to solvethe assigned problem is described. An algorithm of determining the angles of the actual position of the IO ASDon a GSP is presented. The results of verifying the method using the actual devices of the TGS are given.</p>IO ASDTGSGSPcoordinate systemcontrol systemmirror control elementangular positionПО АВУТГСГСПсистема координатсистема управлениязеркальный контрольный элементугловое положение[1.
