Solution of the problem of remote sensing small spacecraft onboard equipment integration through mathematical and simulation modeling of its operation

Due to the ever-increasing complexity of target tasks solved by remote sensing small satellites, and increase of the operational period of their active existence, problems arise in ensuring reliability and trouble-free operation of satellite payloads and spacecraft as a whole. To solve these problems, an advance in design, construction and management technologies is required. In contrast to the use of the principles of redundancy and backup of the main functional units of the on-board system component (OSC) in order to improve reliability and survivability, the problem of intersystem integration of OSC is considered, which allows to change the behavior and structure of the system not only at the design stage, but also during the target operation.
