The article presents the results of the analysis of the need for unification of tethered telecommunication high-altitude platforms (HAP). Possible ways of unification and standardization of HAP, as well as criteria and methods of their structural optimization are considered. It is shown that one of the methods for increasing the efficiency of telecommunication networks is the unification of requirements, component parts and their composite systems. The requirements that should be laid at the stage of setting a technical task for product development are given and it is shown that such parameters as the repeatability factor, the applicability factor, the inter-project unification coefficient are used to assess the level of unification. It is shown that to solve the problems of hardware-software unification and ensure information compatibility, it is necessary to develop appropriate models that take into account the specifics of modern information transmission systems in HAP. The rationale for using the apparatus of logical-dynamic models for solving unification problems is proved, and their joint use with network models allows to formalize the information necessary for solving the problems of hardware-software unification of HAP and ensuring their information compatibility. © Springer Nature Switzerland AG 2018.
