HOLDING METHOD OF GEOSTATIONARY SPACECRAFT Russian patent published in 2019 - IPC B64G1/24 

FIELD: astronautics.

SUBSTANCE: invention relates to the space equipment. In the method of holding a spacecraft (SC) in a given range of longitudes and latitudes of a working position on an orbit, calculating inclination corrections on two nominally opposite active sections (AS), calculating current vectors of eccentricity for one and the same moment – end moment of second AS so that in first version engine thrust is considered only at first AS, in second version engine thrust is considered only at second AS, according to minimum deviation of one and the other eccentric vectors from target vector, working AS and corresponding engine are selected. Stable centripetal effects of spacecraft evolution on longitude and evolution of SC eccentricity vector on orbital position are generated and maintained by the whole set of regular corrections.

EFFECT: increased accuracy of longitude retention, narrowing of spacecraft retention limits.
