A Multi-Step Sequential System Optimization Design Method for Upper Stages

This paper proposes a new approach in multi-step sequential system optimization (MSSO) to implement conceptual design for satellite upper stage with maneuver the conditions close reality. In this method of design, there are two main cycles; trajectory cycle and optimal cycle, each one is correlated other another called configuration. optimization, objective place destination orbit, using minimum amount fuel consumption. has been introduced three-dimensional genetic algorithms inside other. addition, selecting suitable engine carried out cycle. Convergence exclusion configuration subsystems The innovations implementation according which performed step by step, orbital approach. Choosing desirable criterion process proper coefficient convergence among considerable characteristics paper. Validation stages world.
