ATTITUDE DYNAMICS INDUCED BY THERMAL TRANSITIONS ON A SPIN STABILIZED CABLE BOOM SYSTEM Conference Paper

abstract

• This paper analyzes the attitude dynamics excited by orbit thermal transitions (sun-to-shadow or viceversa) of a spin stabilized satellite carrying four equatorial antennas, with a tip mass at their ends. Figure 1 shows a simplified, one unit, configuration. The antennas are assumed of having no bending stiffness. These dynamics are induced by the Coriolis forces originated by the variation of the antenna length. A mathematical model of these effects has been produced. The experimental data, output by the fine 3-slit star mapper sensor of the San Marco 5 spacecraft, are analyzed by means of a new best-fitting technique (CAM), here developed (Annex A). The comparison between the model integration and data shows an excellent match. Finally it will be shown, by a simplified thermal model, a method of computing the temperature profile.
