METHOD OF CONTROL OF CLUSTER OF SATELLITES IN GEOSTATIONARY ORBIT (VERSIONS) Russian patent published in 2006 - IPC B64G1/10 B64G1/24 B64G1/44 

FIELD: control of group of satellites in one and the same orbit or in crossing longitude and latitude ranges of geostationary orbit.

SUBSTANCE: proposed method consists in measurement of parameters of satellite orbits, determination of orbital elements, comparison of them with required ones and performing of correcting maneuvers with the aid of thrusters. Satellite inclination vectors are brought to circular areas of their permissible change which are spaced apart so that angle between line connecting the end of vector with center of its circular area and direction to Sun should exceed right ascension of Sun by 180°. According to first version, vectors of satellite eccentricity are shifted to similar circular areas so that similar line lags behind direction to the Sun by half angular displacement of vector over circumference of its natural drift within circular area. Then, distances between satellites are changed within required limits compensating for quasi-secular increment of inclination vector and correcting eccentricity vector so that at passing the center of interval between point of circumference entry of its natural drift to its circular area and point of exit from this area, line connecting the center of this circumference and center of circular area coincide with direction to the Sun. In case circular area of permissible change of each eccentricity vector is close to circumference of its natural drift (second version), said line for this area is matched with direction to the Sun and no correction is made in this case.

EFFECT: saving of propellant for correction; protracted flight of satellites at safe distance.
