To determine resources reserves of the spacecraft (SC) in the design process of the basic space platform of the SC we applied the common approaches for effective design based on the functional analysis in assessing nominal spending resources of SC to implement certain features and design methods for the SC critical mass, limited by energy characteristics of launch vehicles. The paper presents a formation method of reserves on-Board resources (mass and energy consumption) for additional payload to determine and select the design parameters of the spacecraft, containing a complex of mathematical models of SC establishing the analytical dependences of mass and power consumption for additional payload, depending on the design parameters of the SC.
