Abstract: FIELD: space engineering; creation of satellite systems for observation of objects on earth surface from space. SUBSTANCE: artificial satellites are injected into geosynchronous orbits at inclination  , where m and n are respectively figures of draconic satellite periods and effective earth-rotation periods (taking into account regression of nodal line) in recurrence period of satellite airway; orbits of satellites are selected on the condition of simultaneous passage of equator of Earth by all satellites at angular distance between them equal to 180 deg/(mN) at N=2K and 360 deg/(mN) at N=2K + 1, where K is natural number. As a result, width of observation band required for each satellite is reduced in proportion with total number of satellites at continuous observation of Earth surface. EFFECT: enhanced efficiency. 4 dwg
