| Abstract: | By considering the physical condition of the multilayer insulation（MLI） of the satellite,the temperature field and infrared radiation of the thermal control coating is established with the numerical heat transfer and the finite volume method. Satellite structure model is established. Concept of infrared radiation sensitiVi- ty is put forward and the formula is detruded based on degradation of the thermal control coat- ings. Temperature field of spatial satellite is numerical calculated, and compared with remote data. At last, in- frared radiation and infrared radiation sensitivity are studied. The analytical results show that temperature field model of spatial satellite is reasonable, and fussy calculation of temperature and infrared radiation caused by degradation of the thermal control coatings is escapable under the infrared radiation sensitivity. |
