The article considers the development of service systems computer models on board the
spacecraft. We describe existing approaches to computer modeling, their features for
such technical systems; propose a new approach which, firstly, allows us to consider the
various physical interactions that occur in the system, secondly, to structure the model
and, thirdly, to present it as a uniform element set. The study suggests the algorithm that
makes it possible to build a software representation of the state vector and propose set-
tlement functions of the system under study, based on a formal description of its model,
made in accordance with the described approach to modeling. On the base of the algo-
rithm we developed a computer program. The study estimates the computer program
speed and the possibility of using an original approach to modeling service systems on
board the spacecraft in order to inform spacecraft flight control and describes the
measures to further performance improving
