| description | FIELD: aviation instrumentation. SUBSTANCE: autonomous correction device of inertial navigation system incorporates unit of chart of terrain features, first, second and third comparators, unit of chart of increments of gravity acceleration, prediction unit, differentiator, gravimeter, first and second multimodal comparators, measurement vector unit, unit of optimal Kalman filter, astrosight, unit computing predicted values of horizontal coordinates of stars, timer. First comparator is coupled to converter of signals from transducers of noninertial structures. Second input of prediction unit is connected to differentiator that is coupled to converter of signals from transducers of noninertial structures. Unit of optimal Kalman filter is connected with corresponding outputs to corrected inertial navigation system. Outputs of units of chart of terrain features and chart of increments of gravity acceleration and of first comparator are connected to proper input of prediction unit. Outputs of both comparators are coupled to first multimodal comparator. Third comparator is connected with second input to unit computing predicted values of horizontal coordinates of stars. Outputs of unit computing predicted values of horizontal coordinates of stars are coupled to timer and proper outputs of corrected inertial navigation system. Second multimodal comparator is coupled with outputs to corresponding inputs of measurement vector unit. Two inputs of second multimodal comparator are connected correspondingly to outputs first multimodal comparator. EFFECT: increased correction precision of inertial navigation system. 3 dwg |
