When studying complex technical systems, researchers often face the problem of modeling its functioning. For example, an air-space monitoring system is a complex, geographically distributed set of interconnected information media (IC). As a rule, it is not so difficult to create a model of individual IE with a certain degree of detail, but to synthesize a set of IE operating in a single information field and according to a common plan, the task is difficult, especially if it is necessary to determine the quality of the tasks they solve in the interests of consumers. Consumers here are various organizations for which information from the air-space monitoring system is of some interest. In order to determine the potential characteristics of air-space monitoring systems, models that do not take into account the peculiarities of the functioning and interaction of information tools are usually used. The article considers the model of the air-space monitoring system, which takes into account the peculiarities of the functioning of information means operating in different ranges of radiation, the peculiarities of obtaining information, the mutual location of celestial objects and others. In order to simplify the modelling, the article assumed that the entire IP fleet of the air-space monitoring system was conditionally divided into three groups on the principle of work and two groups on the stage of their application. Based on the principle of operation, radar stations (radar), optical-electronic (OEC) and radio engineering complexes (RTC) are selected. According to the stage of application: in the first stage, radars working for the detection of objects in aerospace space are used. These tools have good search capabilities, but relatively little ability to obtain non-coordinated information (NCI) [1]. Such means are defined by sector zones of action limited in elevation angle and azimuth with center having coordinates in geocentric coordinate system (SK). With regard to the second phase, IEs with the capability of obtaining an NIR on objects in aerospace, such as CEC and RTC, are used. The above mentioned means were defined by circular zones of action limited by elevation angle with center having coordinates in geocentric SK. In order to simulate the work of information users, it is proposed to use circular zones of action limited by the angle of elevation with the center having coordinates in the geocentric SK. In order to verify the proposed model, simulation was carried out, the results of which were compared with the data presented in the interface control document, at the same time the maximum discrepancy between the control and model data was 10-2.The developed model allows to solve a wide range of tasks: to assess the effectiveness of the air-space monitoring system by determining the spatial-temporal and probabilistic characteristics of the IS both of the system itself and of consumers; Determine the spatial location, composition and structure of the air-space monitoring system at the specified performance indicators; Assess IP capacity; Assess the quality of measurement identification from spatially separated ICs and information integration; Justify the technical requirements for IE in order to ensure the specified level of application efficiency.
