FIELD: instrument making.
SUBSTANCE: in process of control simultaneous with measurement of condition of a controlled object, comparison of accelerations of the controlled object is carried out. At the same time absolute angular and linear speeds of the object are measured with sensors of angular speeds and sensors of speeds of the inertial system. The device comprises summators, multipliers, functional converters, converters of coordinates and comparators, connected so that output signals of summators are compared with threshold values of estimates of accuracy of measured and calculated accelerations. Deviations of estimates of accelerations from their measured values on comparators of the device serve to record the moment of failure of the inertial navigation system.
EFFECT: expansion of functional capabilities.
