Aiming at the installation requirements of a certain type of spacecraft involving star sensitivity, the research and development of aluminium alloy star sensitive bracket, titanium alloy star sensitive bracket, composite material star sensitive bracket and 3D printed star sensitive bracket have been completed. The simulation study of thermal stability is given. In order to investigate the actual thermal stability performance of the star-sensitive bracket, to quantify the thermal deformation characteristics of the star-sensitive bracket under the overall temperature condition, a measurement scheme combining photogrammetry and theodolite measurement is used to conduct a thermal stability test and deformation test. The test proves the feasibility of the measurement scheme and provides some data support for the improvement of the star-sensitive support structure.
