A. H. Tavakkoli; A. Kalhor; S. M. M. Dehghan

Volume 5, Issue 2 , July 2012, , Pages 59-68

Abstract
  In this paper the performance of a three Degrees Of Freedom simulator is evaluated. This platform is considered as an important instrument generally used in performance tests of spacecraft attitude determination and control subsystem on the ground. A hemispherical air bearing is used to provide micro ...  Read More
