With the low-altitude airspace opening, the role of surveillance technology in ATC system has increasing prominent. This article used application of image extraction technology, algorithm processing, data fusion and transmission to improve the reliability of surveillance and set up a new structure of network. Finally, we used computers to achieve a new type of low-altitude surveillance system.

The paper proposes ways to reduce the time and improve the quality of development of electronic equipment using computer simulation. The paper considers an example of the development and debugging of a radio-electronic module, which has found its direct application in a local navigation system that operates on the basis of the method of point landmarks. The paper considers a hardware-software complex for the implementation of the study of the health of both individual functional units and radio rangefinder equipment as a whole, as well as for the modernization of the radio-electronic module of the navigation system. The various computer simulation environments available today allow the development and design of electronic equipment at various levels. In the proposed work, computer simulation was carried out in MATLAB / Simulink, LabVIEW, Multisim and MicroCap. The work also provided for the possibility of using data collection and processing modules, which provides the opportunity in one software development and modeling environment to compare the results obtained using simulation modeling and physical research of the object. The result of the work is a hardwaresoftware kit of the radio-electronic module of the navigation system through which it is possible to evaluate the influence of various external influences on the accuracy of determining the range from the interrogator (moving object) to the transponder (stationary beacon).

Рассмотрен вопрос о вариантах контроля формирования точности локальной системы навигации (ЛСН) с использованием ее базового параметра - момента приема рабочего сигнала в ЛСН. Приведены результаты измерения инструментальной временной погрешности разрабатываемой локальной системы навигации. The paper considers the question of control options for the formation of the accuracy of the local navigation system (LSN), using its basic parameter - the time of reception of the working signal in the LSN. The results of measuring the instrumental time error of the developed local navigation system have been presented.

In this paper, the problem of minimization of the number of local navigation system (LNS) reference points (RPs) and RPs’ location optimization is posed according to the criterion of ensuring the factor of geometric dilution of precision (GDOP) averaged over the space is not worse than a given one. According to authors’ best knowledge, this is the first time such a problem has been posed and solved. An approximate numerical solution to the problem based on a genetic algorithm is proposed. The effectiveness of the proposed method is assessed by simulating the placement of a different number of ranging LNS RPs in rooms of various configurations and comparing the result with the quasi-optimal result of a complete numerical search of all possible locations of the LNS anchors. The conclusion is made on the applicability of the proposed method for solving the problem and the prospects of building on its basis a tool for automating the development of positional LNS to reduce the development time and the cost of infrastructure.
