Abstract

Separate samples of the engineering systems influence different objects without the self- control regarding the  accuracy of the impact. From technical point of view this implies  the need to substantiate the requirements concerning the accuracy of the guidance and performing  the studies  of the factors, influencing the accuracy characteristics of the guidance systems. If we consider the  dependence of the guidance errors (  in  the azimuth and elevation  angle) on the orientation errors, then their functional dependence will be determined . In such case it is not correct to apply the formula for the determination of the root-mean-square deviation of the sum of the independent random values and there appears the task  of determining the impact  of such class of errors in the general errors and determination of the possible ways of their minimization. The results of the study of the orientation errors impact on the guidance accuracy of the directed system are presented. For emitting radioengineering systems referencing and orientation errors are approximately 60% of the guidance errors. The given research shows the heterogenous character of the orientation errors impact (both by the value and by the degree of the impact) on the guidance errors. Analytical study of the guidance errors in the  multidimensional area of arguments  has some problems, taking into consideration large volume of the analytical expressions and multidimensional character of the dependences. The results of the simulation experiment of determining the character of the orientation errors impact on the indices of the guidance errors are submitted. It was determined that the guidance errors also depend on the target  direction. The study of the guidance errors in the area of the value of the possible target  directions was performed . The availability of the areas of minimal and maximal guidance errors in the area of the azimuth and elevation  angle values  was determined, the location of these areas depend on the relation of the orientation errors values. For the application of the facilities of the directed action the usage of the method of timely rational orientation of the carrier for the reduction of the guidance errors is suggested.
