The article proposes a method of forming the requirements for the correction system of the inertial navigation system based on the solution of multi-parameter optimization problem, which will justify the required values of navigation parameters for different types of aircraft systems in order to improve their combat effectiveness. The essence of this method is to select the required optimal values of indicators of the accuracy of navigation and the accuracy of correction, limited by regulatory and technical documentation and the resources of the computing environment on the one hand and the achievement of maximum combat effectiveness on the other hand. The obtained optimal values of the navigation accuracy parameters and the rate of increasing the error of the inertial navigation system coordinates number determine the frequency of inertial navigation system correction. The dependence of computing resources on the accuracy of correction is obtained on the basis of the revealed relationship between the navigation accuracy and the size of electronic terrain map. And on the basis of the revealed connection between the accuracy of correction and the number of sectors of the electronic terrain map, the dependence of computing resources on the accuracy of correction is obtained. The solution of the multiparameter optimization problem defined the relationship of the frequency of correction and the accuracy of navigation at a constant slew rate of the error number of coordinates. This solution allows to determine the optimal value of the navigation accuracy and the correction accuracy, providing maximum combat effectiveness.
