WEIGHTLESSNESS OFFERING APPARATUS FOR DEPLOYMENT TEST OF SATELLITE PAYLOAD ANTENNA

摘要

PURPOSE: A weightlessness offering apparatus for testing the deployment of an antenna installed on a satellite is provided to improve the reliability and accuracy of an antenna deployment test by supporting the weight of an antenna to create a perfect weightless condition. CONSTITUTION: A weightlessness offering apparatus for testing the deployment of an antenna installed on a satellite comprises a base frame(100), a fixing shaft(200), a support beam(300), first and second sliding units(400,700), a rotating unit(500), a support cable(600), and a bracket(800). The fixing shaft is vertically installed on the top of the base frame. The support beam is horizontally formed on the top of the fixing shaft. The first slide unit is installed on the top of the support beam and slid in the horizontal and vertical direction of the support beam. The rotating unit is installed on the top of the slide unit and allowed to rotate. The second slide unit is formed in the bottom of the support cable and slid in the horizontal and vertical direction. The bracket is formed on the bottom of the second slide unit and coupled with an antenna.
