Abstract:

The feasibility of creating a promising global system for monitoring the geodetic parameters of the Earth (GSMGPZ) is determined both by the need to eliminate the existing shortcomings, including in coordinate systems, to transfer it in the coming years to new accuracy characteristics that are several times higher than the achieved level, and the need to provide in geodetic terms a number of new promising areas of use of the GLONASS system. This article proposes a methodology for substantiating the ballistic construction of an orbital system of spacecraft for remote sensing of the Earth for solving problems of monitoring its gravitational field, taking into account the peculiarities of the functioning of onboard measuring equipment of various types and the possibility of transmitting measuring information to ground points.

Abstract:

The article deals with the process of forming optimal trajectories of the aircraft (aircraft), ensuring the achievement of the final parameters of motion based on a single numericalanalytical method effective from the point of view of computational costs. As a method of solving the problem, it is proposed to use the method of deformed gradients, which allows solving a complex nonlinear multipoint extreme - boundary value problem of controlling finite parameters. The paper are provided a mathematical model of aircraft movement with operational changes in target designations in flight, an algorithm for calculating nominal parameters of aircraft movement and an algorithm for calculating perturbed aircraft parameters. The proposed method made it possible to obtain an optimal terminal control function with low efficiency of the control bodies along all three axes with insignificant linear accelerations of the center of mass. The obtained scientific results allowed us to deduce graphical dependencies of the terminal miss parameters.

Abstract:

This article offers two options for constructing an antenna system of a frequency synchronizer that provides the necessary conditions for the functioning of a solar active phased array antenna (SAPAA) placed on a geostationary carrier with an operating frequency of 2450 MHz. The results of the evaluation of the permissible relative instability of the frequency of the synchro signal of the antenna system of the synchronizer are presented, which indicate the practical feasibility of both construction options. The calculations of the SAFAR characteristics allow us to judge the possibility of transmitting information and energy from a source on a space carrier to a consumer on the Earth's surface (sea), in space and airspace.

Abstract:

Implementation of control actions and interaction of corporate management systems is carried out through the resources of communication systems. The information directions formed in this case are a direct reflection of the structure of the corporate management system. Corporate management systems use the resources of public communication networks, which are elements of international cyberspace, through which the structure of the communication network and the corresponding structure of the corporate management system can be opened. The higher the awareness of the source of destructive influences on the structure of the target control system, the higher the efficiency of the implementation of destructive influences (physical, electronic, information technology), therefore, in order to take timely measures to reduce efficiency, or to prevent the implementation of destructive influences, it is necessary to have data on their awareness. sources on the structure of the target corporate management system.

Abstract:

The article considers the issues of interference immunity of special - purpose communication networks, built on the basis of radio relay stations with adaptive modulation and packet switching. The main attention is paid to assessing the effect of electronic suppression equipment on the transmission rate in radio relay intervals. The article presents the results of calculating the parameters of the worst interference with a limited average power affecting the radio - relay interval with typical adaptive modulation algorithms. It is shown how based on game theory methods we can increase the noise immunity of radio relay intervals by appropriate optimization of adaptive modulation algorithms, taking into account the controlled values of the current and average noise power, as well as the ratio of inertia of control and suppression circuits.

Abstract:

The article presents a model for monitoring the technical condition of radio facilities of the main adaptive radio line in the process of functioning. The model is designed to identify gradual hidden failures that occur during the operation of radio equipment due to deviations (drift) of parameters beyond the tolerance limits. To identify this type of failures, eliminate misalignments, annual maintenance (scheduled preventive maintenance system) is currently being carried out with the involvement of engineering and technical personnel and measuring instruments. As practice shows, carrying out maintenance by lowskilled engineering personnel leads to radio equipment inoperable. In this case, in order to move from a planned preventive strategy of maintenance of communication facilities and systems to maintenance according to the actual technical condition, it is necessary to develop reliable automated means of monitoring the technical condition, operating both in continuous and discrete modes.

Abstract:

A problematic issue in the operation of weapons and military equipment in conditions of negative temperatures in a cold climate is starting a diesel engine after a long stay. The industry produces special auxiliary equipment. In this regard, heat generators have become widespread - individual and group heaters of flame and infrared types, which provide a solution to the problems of pre - start preparation. In addition, there are starting aids. It is known that the reliable start of a diesel engine is influenced by such factors as the temperature of the air charge, the torque of the crankshaft, the conditions for spraying fuel, the activity of heat exchange processes and the tightness of the joints of the parts of the cylinder - piston group. An effective solution to this problem is seen in the use of lightweight fuels with an electric torch device.
