Active vibration isolation and high-precision pointing system for high-precision large deployable antennas for space radio telescope

摘要

The paper is devoted to the problem of providing required precision parameters of high-precision large deployable antennas space radio telescope (HLDA SRT) small stiffness of antennas entails its high sensitivity to microdinamical factors arising in the orbital flight. To provide necessary precision of geometrical characteristics, one have either to diminish microdinamical factors or to implement active or passive vibration protection systems. A conception of a system of active vibration isolation and pointing HLDA SRT is presented.
