WAY TO CONTROL ROCKET FLIGHT OVER MID-COURSE Russian patent published in 2003 - IPC

FIELD: rocket engineering, rocket design. SUBSTANCE: angular deviations of rocket from target sight line are measured and rocket control commands are formed in proportion to its linear deviations found by angular deviations of rocket from target sight line and range to rocket. Luminous intensity of airborne radiation source prior to passage through atmosphere and range to rocket at moment of engine separation are established tentatively. Illuminance of photodetector of rocket direction finder at moment of engine separation and its present illumination intensity in mid- course of rocket flight are measured. Present range to rocket found by certain dependence is utilized to form commands for control over rocket. EFFECT: increased accuracy of rocket guidance on target. 2 dwg
