IMAGE SHIFT COMPENSATION METHOD Russian patent published in 1994 - IPC

FIELD: photography. SUBSTANCE: method involves turning of aerospace vehicle through roll and yaw angles, its positioning so that angular pitch, roll, and yaw velocities, as well as pitch angle are zero; photofilm is displaced during exposure at compensating speed calculated by using relevant equation with due account of results of measurement of vehicle latitude argument, focal parameter, eccentricity, and inclination of vehicle orbit, vehicle perigee argument, and current value of vehicle yaw angle, as well as results of calculation of angular velocities of ascending node of orbit and of vehicle made by using relevant equation. EFFECT: improved accuracy of image shift compensation by accounting for linear velocity of the Earth at point of photography during vehicle turning through roll angle. 1 dwg
