The possibility of using system state observers in the orientation and stabilization systems of small space vehicles is considered. A comparative assessment of systems with a system state observer and classical execution is carried out. For comparison the criteria of stability of automatic systems, criteria for assessing quality in steady-state and transient modes of operation, criteria for assessing quality under the action of random disturbing influences were used. The method of mathematical modeling is used as a research method. For its implementation, mathematical models of systems and their components have been developed. Simulation is done in state variables. The synthesis is based on the apparatus of modern control theory. It has been established that the use of a system state observer in the orientation and stabilization systems of small space vehicles will not only reduce their weight and dimensions, increase their reliability and reduce the cost of components, but also provide practically the same control quality indicators as in the classical version.
