METHOD OF SUPPRESSION OF INTERFERENCE CAUSED BY VIBRATIONS OF ELASTIC STRUCTURE OF TRANSFORMABLE SPACE ANTENNA IN THE COURSE OF OPERATION AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2008 - IPC B64G1/00 B64G1/22 B64G3/00 

FIELD: space engineering; large-sized high-precision transformable structures.

SUBSTANCE: proposed method consists in monitoring acceleration and respective deviations of geometric parameters from theoretical magnitudes at check points. Monitoring is carried out continuously in real time. Check points are made for all shape-forming members of antenna structure. Device proposed for realization of this method has geometry and acceleration monitoring system which is made in form of combined spatial position and acceleration sensors. Sensors are made in form of miniature three-axis units of gyroscopes-accelerometers which are electrically connected with onboard information-and-measurement control system via analog-to-digital converters. Onboard information-and-measurement control system is electrically connected via respective power amplifiers with actuating members of extended structural members of spacecraft.

EFFECT: enhanced reliability of parameters under test; improved characteristics of antenna.
