Aerospace Instrument-Making Annotation << Back Methodology for Selecting the Height of the Placement of a Multi-Satellite Orbital Grouping of a Communication System Based on Minimizing the Cost of Launching Spacecraft Abdurakhimov A.A., Nechaev I.Y. This article describes a technique for choosing the orbit height of a small spacecraft as part of an orbital troupe of a space communication system corresponding to the minimum energy costs for the removal of all the spacecraft of the grouping. The dependence of the analysis of the infl uence of the height of the orbit of a small spacecraft on the cost of resources to compensate for the aerodynamic drag of the vehicle of active operation of the devices are formulated. Keywords: orbital grouping, small spacecraft, communication spacecraft, orbit height, total mechanical energy, aerodynamic drag. DOI: 10.25791/aviakosmos.12.2023.1380 Pp. 39-47.
