Abstract

The efficiency of the operation of information-measuring systems of spacecraft (and, primarily, optical systems) depends on the thermal deformations of the load-bearing structure, on which they are placed. Small angular thermo-deformation displacements of the optical axes, which are caused by the nonuniformity of the temperature field of the load-bearing structure, lead to significant linear deviations of the measurement points due to the large distance of the measurement objects from the spacecraft’s orbit. The article discusses the dynamic characteristics of the automatic temperature field stabilization systems of the load-bearing structure of a small spacecraft under the influence of external and internal disturbances typical of this type of objects.
