TRANSIENT TEMPERATURE AND THERMAL CURVATURE BEHAVIOR OF SOUNDER ANTENNAS ON ALOUETTE SATELLITES,

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)
