METHOD FORMING SIGNAL CONTROLLING POSITION OF SENSITIVITY AXIS OF GRAVIMETER INSTALLED ABOARD AIRCRAFT WITH ITS REMOTE SETTING BY PLUMB LINE Russian patent published in 2004 - IPC

FIELD: aviation instrumentation, aerogravimetric operations in which gravimeter is utilized as transmitter of primary information. SUBSTANCE: collection of signals measured with the help of aboard inertial navigation system mounted in aircraft and corresponding to angles of roll, course and pitch, increments of speed caused by Coriolis acceleration and curvature radii are employed to form signal corresponding to angular velocity of sensitivity axis of gravimeter. Difference between newly formed signal and signal corresponding to angular velocity of accompanying trihedron computed with the aid of aboard inertial navigation system is established. Signal controlling position of sensitivity axis of gravimeter is formed by signal of closure error of angular velocities of real motion of sensitivity axis of gravimeter and plumb line realized in precision inertial navigation system. EFFECT: increased precision of remote setting of sensitivity axis of gravimeter. 11 dwg
