Method for adjustment of axles of sensitivity of accelerometers is claimed in which to hydro-stabilized platform one installs three accelerometers with direction sensitivity axles of those in parallel to axles of three-dimensional system of coordinates related to gyro-stabilized platform, by means of lines applied to body of each accelerometer. After that to gyro-stabilized platform with three accelerometers is installed on rotary table of angle-measuring device by means of which one determines deflection of three normal to each other axles of sensitivity of accelerometers from coordinate axes of three-dimensional coordinate system. After that one determines deflection from vertical and horizontal position for each of lines applied to the bodies of accelerometers through formation with video-camera of image of those lines, transfer of images obtained to computer (C) and liner approximation of those. After that by means of computer one forms corrections that are used for correction of spatial position of sensitivity axles of accelerometers. Such implementation of the method increases accuracy of adjustment of axles of sensitivity of accelerometers in three-dimensional space and as result substantially increases accuracy of measurement of accelerations in inertial navigation system or accuracy of measurement of anomalies of acceleration of gravity with gravimetric system. |
