The purpose of the work is to test and refine models of SS operation and efficiency, MLM for controlling and modeling SC dynamics, and statistical methods for math modeling of SDO motion. The development of control algorithms and simulation modeling of the OSS and SIC controlled motion. The following results were obtained. The main regularities of shape changes of a nearly circular Earth orbit under aerodynamic and control forces are defined. Analytical expressions of orbit parameters changes under the acting of solar pressure and third body gravity are constructed. The models of the ETS with a thermoelectric coating dynamics were improved. An algorithm for preliminary processing of SDO images using a neural network was developed. The algorithm for determining the orbital service object pose with an unknown shape was improved. The math models of operational planning of services and synthesis of the SS OSS orbital structure in low orbits were improved. The complex math model of the SIC functioning was improved. A math model of the functioning of the SS modules for Earth's surface darkening is tested. Algorithms for numerical methods of deterministic search were developed to optimize the design parameters of the space industrial platform. The statistical method for modeling the SDO motion was finalized. Embedded verification methods of the autonomous SS functioning were developed. The state of the market for transport-space services and satellite communications is defined. Methodological support for rating the experts' competence in rating the technical level of rocket-space technology samples was developed Product Description popup.authors Avdieiev Anatolii M.
