Speech Title：Digitalization of creation multi-satellite Earth monitoring systems

Abstract: This talk presents a life cycle model of multi-satellite space monitoring systems, including an independent stage of maintenance and repair. A new approach to formalizing system requirements based on target objectives is proposed, taking into account current trends of the global market of geoinformation products and services, as well as the market of spacecraft. For the first time, conceptual, structural and process models of a "digital factory" for the serial production of small satellites based on the principles of a cyberphysical system have been formed, justifying the choice of a matrix type of production system. A general scheme for digitalization of experimental testing of small satellite as part of multi-satellite space systems is proposed, based on the use of digital tools to optimize test volumes. The architecture of a distributed ground-based infrastructure for control a multi-satellite space monitoring system is considered, which involves the digitalization of information storage and processing processes.  An original system of criteria and a methodology for evaluating the effectiveness of small spacecraft deorbiting from multi-satellite systems has been developed, based on methods of integral relative estimation and confident judgments. The proposed approaches have found their practical application in the design, manufacture, ground-based experimental testing and operation of the “AIST” small satellites series. The developed design methods, control algorithms and manufacturing technologies have been successfully tested under the guidance of the author within the framework of the activities of the ground-based control center, as well as the experimental cyberphysical factory ("digital factory") for small Earth remote sensing spacecraft created at Samara University. The results of the work can find further can be further applied to accelerate the creation of multi-satellite space-based Earth monitoring systems.
