Paper Abstract

When a space object in spin stabilization, three-axis stabilization or roll-motion is running on orbit, heat transfer such as radiation and conduction takes place, which makes the temperature field on the object in an unsteady state. Besides, the methods of stabilization on orbit also affect the temperature distribution as well as projected area to a spaceborne sensor, thus influence IR signatures of the object. In this paper, by developing the attitude dynamics as well as the heat transfer models of an orbital object, the infrared characteristics are calculated and analyzed. Results indicate that temperature demonstrates periodical variation, and stabilization states of the space object have important impact on the temperature distribution and IR radiant intensity.
