METHOD OF OPTIMISING DYNAMIC CONDITIONS FOR OPERATION OF GRAVITY-SENSITIVE INSTALLATIONS IN CONDITIONS OF MICROACCELERATION ON-BOARD ORBITING SPACECRAFT AND DEVICE TO THIS END Russian patent published in 2009 - IPC B64G1/22 B64G1/36 

FIELD: physics.

SUBSTANCE: method involves measurement of disturbing dynamic impact on payload using accelerometres on-board a spacecraft and vibration insulation of installations in the region of high and medium frequencies (from 0.01 to 500 Hz). The current direction of the vector of on-board quasi-stationary (up to 0.005 Hz) acceleration at the centre of rotation of the vibroprotective platform with a gravity-sensitive installation on it, is determined from the measurements taken. The axis of this installation is stabilised at a given angle relative the said vector in automatic mode. To realise the method, a device is used, which contains the said platform, which is a precision servo-system. The system is meant for providing a given stable angular position of the said gravity-sensitive installation relative the slowly varying vector of quasi-stationary acceleration. Simultaneously, there is vibration insulation of the given installation from high and medium frequencies of on-board dynamic impact.

EFFECT: increased reliability of results of scientific-technological experiments with gravity-sensitive systems due to monitoring the quasi-stationary component of microaccelerations.
