METHOD OF TARGET INDICATION BY DIRECTION FOR SYSTEM OF GUIDANCE OF CONTROLLED OBJECT Russian patent published in 1998 - IPC

FIELD: methods of target indication by direction for systems of guidance of controlled objects of air-surface class. SUBSTANCE: method includes measurement in some point out of target of target coordinates relative to this point, determination of latitude and longitude of this point, calculation of elevation of this point above sea level, latitude and longitude and elevation above sea level of the target location point. In calculation of elevations, use is made of digital map of the target location region and this point; transmission of latitude, longitude and target elevation to controlled object where latitude and longitude of the controlled object carrier are determined; measurement of carrier flight elevation, angles of orientation of its longitudinal axis and angle of orientation of sight axis of system of guidance of controlled object carrier in horizontal and vertical planes; calculation of controlled object carrier elevation above sea level with use of digital map of region in which flight route of controlled object carrier runs, angles of orientation of vector of distance; controlled object carrier - target, and also angles of orientation of sight axis of controlled object guidance system relative to vector of carrier to target distance in the specified above planes, and sight of controlled object guidance system is turned towards reduction of angles the last indicated, down to their zero values. EFFECT: increased distance between controlled object carrier and target at the moment of completion of target indication by direction of guidance system of controlled object in cases of action of aircraft carrier of controlled object against small-size ground targets. 3 dwg
