In this paper, it mainly researches the calculation algorithm of positioning and adjustment in the unmanned air vehicle formation. the calculation algorithm of the unmanned air vehicle in the two-dimensional plane is built. In order to be more in line with the actual situation, the model is further optimized, under the condition that the unmanned air vehicle meets the pure azimuth and passive positioning, and the model is consisted by the mapping method and polar coordinate system. Finally, the calculation algorithm of the passively receipting positioning model about unmanned air vehicle is given, and the calculation algorithm of the adjustment scheme of the unmanned air vehicle formation is implemented.

The paper discusses the preconditions of the methodology development of diagnosis system for assessing dynamic impact of the rolling stock on the basis of processing and analysis of data obtained in operation on the results of measurement of parameters that characterize dynamic vibration processes of the mechanical system of "rolling stock track". On the basis of usage of the processing methods of time series and stochastic processes there has been established the relationship between these dynamic processes and wheel defects, and designed experimental data processing algorithms, which in the future will be an integral part of the intellectual systems of decision making when assessing the impact level of the rolling stock on the track. The article presents some results of the experimental and theoretical research of the rail accelerations data, which have been registered during passing of the train. The computational algorithm of the specialized pre-processing of the multidimensional signal recorded by this system is described. The advantage of this algorithm is that it does not require additional information about the train speed on the section equipped with the monitoring system, about the number of wheel pairs of locomotives and train cars, and about the distances between the wheel pairs. Based on the processing results of accelerations of the rails there have been set the parameters of increase in all statistical indicators with increase in the train speed. It is noted that the level of indicators for accelerations of the rails in the vertical direction is twice as high as the corresponding parameters in the horizontal direction.
