The paper considers the problem of complex optimization of the parameters of spacecraft and the space system for Earth remote sensing (ERS). The development (modernization) of equipment and technologies in the planned period is taken into account. The problem is formulated in a deterministic setting. The criterion for solving the task is the reduced total costs for the implementation of the ERS space system project during modernization in the planned period. When searching for a rational solution to the problem, its parametric decomposition is used. Variants of spacecraft modifications as part of the system and the program of modernization of the system are formed separately. The vector of variable parameters includes the parameters of the spacecraft modification and the system modernization program, i.e. the number of modifications of this spacecraft and the timing of their creation. The parameters of the ground segment and the base spacecraft are set. The study shows that the most rational approach to solving the problem is to construct a multi-level design research diagram in accordance with the structure of the system. A two-level design research model and a two-level coordinated optimization method are implemented, including a directed adaptation of the top-level design dependencies. The algorithm for solving the problem includes blocks for forming variants of the spacecraft modification, optimizing the modernization program, assessing the target efficiency, and determining the reduced total costs for the implementation of the system modernization program in the planning period. The possibility of increasing the efficiency of future ERS space systems is explored according to the results of solving the model problem. Using the model example, the parameters and the program of modernization of two alternative options for space systems of different altitudes located in sun-synchronous orbits are comprehensively assessed. The estimation of performance indicators of the considered variants of the systems is given. The assessment of technical and economic characteristics obtained on the basis of the model example can be used for a detailed analysis of the efficiency of future ERS space systems in order to predict their development and expand the field of application.
