METHOD FOR SPACECRAFT ORIENTATION CONTROL EQUIPPED WITH AN ONBOARD RELAY COMPLEX Russian patent published in 2021 - IPC B64G1/24 B64G1/28 

FIELD: space technology.

SUBSTANCE: invention relates to space technology. The method for controlling the orientation of the spacecraft (SC) includes mathematical modeling of the spacecraft orbit, measuring the parameters of its angular motion, determining, building and maintaining a given orientation of the spacecraft from them, measuring the angular momentum in the system of power gyroscopes, determining the disturbing moments acting on the spacecraft by the measured parameters of angular motion and the values ​​of the angular momentum of the power gyroscopes. From the entire set of radio signals from geographically separated earth stations of satellite communications, relayed through the onboard relay complex, those whose power changes most strongly with a change in the orientation of the spacecraft are selected. The spacecraft is sequentially rotated around the axes of the associated coordinate system, by measuring the power values ​​of the signals of the onboard relay complex received at the central satellite communication station at different orientation of the spacecraft, the law of change of the selected signals is determined depending on the orientation of the spacecraft.

EFFECT: simplification of spacecraft attitude control, improvement of accuracy and reliability.
