FIELD: control systems of missiles and other flight vehicles. SUBSTANCE: acceleration vector measuring system determines the acceleration projections on the body axes of the flight vehicle in its arbitrary point. In the offered system indirect measurements according to indications of more precise instruments - integrating gyros installed on a gyro-stabilized platform are used instead of the traditional measurement by means of accelerometers. Possibility of measurement of acceleration vector in projections of the body axes of the flight vehicle in any point is attained by taking into account of the flight vehicle angular motion with the aid of the angular-rate sensor unit, angular rate processing unit, vector multiplier unit and double vector multiplier unit. Transformation of output signals of the integrating gyros into accelerations in the body coordinate system is provided by the linear velocity processing unit, orientation determining unit and device for conversion of vector projections from the inertial frame to the body axes. The adder produces the system output signals by addition of accelerations caused by translational and rotary motions of the flight vehicle. Selection of the flight vehicle point subject to the check-up on the side of the measuring system is accomplished by setting of specific magnitudes in the setter of the measurement point coordinates. EFFECT: improved design. 7 dwg
