This analysis demonstrates the impact of thermal deformations on measurement points in spacecraft, suggesting stabilization systems may enhance performance.
The efficiency of the operation of information-measuring systems of spacecraft, and primarily optical systems, depends on the thermal deformations of the supporting structure on which they are placed. Small angular thermo-deformation displacements of the optical axes, caused by the non-uniformity of the temperature field of the supporting structure, lead to significant linear deviations of the measurement points due to the 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 supporting structure of a small spacecraft under the influence of external and internal disturbances typical for objects of this type.
