Abstract : Structural members of the STEM type are presently used as antennas for ionospheric sounding satellites such as Alouette 1 and 2, Explorer 20, and the proposed ISIS series. Since these satellites are spin-stabilized, the STEM antennas experience variations in temperature and consequent variations in thermal curvature, and in average temperature as a result of their changing aspect with respect to the sun. In this report the average temperature and thermal curvature variation of STEMS on spin-stabilized satellites are investigated. The results are used to analyze existing designs of the Alouette class of satellites. (Author)
