FIELD: space engineering, applicable in large-sized high-accuracy transformable structures, for example, reflector-type antennas of space radio telescopes. SUBSTANCE: suppression of interferences caused by elastic vibrations of the structure is accomplished with the aid of a vibration-insulating platform in the form of a space truss. The truss is formed by hinge joints of the space vehicle docking surface and the platform with the vibration-insulating object. The joints are accomplished by single modules of active anti-vibration that can in concord change their length by a command from the control unit and relative movement and velocity transducers. These modules are made in the form of self-braking ball-screw mechanisms providing for a geometric stability of the system with the drives disengaged. The right mode of control of the antenna dynamic structure is set on the basis of physical modulation of the vibration process. EFFECT: expanded functional abilities of the system of space anti-vibration insulation and enhanced accuracy of space transformable antennas in service. 10 cl, 8 dwg
