The analysis of the influence of natural and climatic conditions of the Arctic and Far North on the stability of air connection is investigated in this article. The provision of year-round mainline, interregional and regional air transportation is associated with the complexity of controlling the flight path of aircraft in extreme Arctic conditions. For the Arctic zone, the possibility of using a constellation of low-orbit satellite communication systems is being considered for transmitting data on the position of an aircraft to a control tower located on the ground. In this case, data transmission is possible both using GSM communication through ground stations, and using inter-satellite communication lines.

The article discusses the architectural basis of the cross-platform onboard software for navigation and communication satellites. The functional characteristics of the designed software components are the queues used, the ports, the supported hardware, and the low-level inter-hardware communication protocols. The verbal description of the selected area of knowledge and the formalization of relations between individual entities allows you to move from the architectural basis, limited by physical parameters and the environment for the functioning of software tools, to a descriptive model, which served as the basis for a relational database. An identification method is proposed for unambiguously identifying a specific component of the on-board software with the possibility of performing further actions on it, for example, archiving, retrieving, duplicating, etc. An onboard software component is viewed as a complex entity that contains not only program code, but also a number of attributes that are used during operation. The structural diagram of a relational database is presented. This structure unites and links both information about software components and the electronic document management tool as a whole.

Ion Source—Mathematical Simulation Results versus Experimental Data

et al. 2021

To develop elements of a system for contact-free transportation of objects in space has now become an urgent task for the contemporary space-related activities. The purpose of work that is presented hereinafter was to conduct ground tests of the ion source, which is a key element of the above-mentioned system, and to compare the obtained experimental data with the mathematical simulation results in order to build a refined physical and mathematical model of the ion source. Such model was built on the basis of the classical problem regarding the motion of charged particles in an electrostatic field. Parameters of the ion source have been determined experimentally for several operating modes using various structural designs of the ion source electrodes. Two types of ion optics were tested—with slit and round apertures. Good correlation between simulation results and experimental data has been demonstrated. The optimum ion source operation modes have been identified to ensure minimum divergence angles for the plasma beam exiting from the ion source, which in its turn maximizes the pulse transmitted to the transported object.
