Abstract

科学衛星「はるか」は, スポース VLBI に必要な工学諸技術の実験ならびにスペース VLBI による電波天文観測を行うことを目的として, 1997年2月12日, 宇宙科学研究所の新型ロケット M-V の初号機により打ち上げられた。「はるか」では数々の工学的課題への取り組みがなされたが, それらの中で, ケーブルとメッシュからなる, 有効開口径8cmのパラボラアンテナの軌道上での展開が, 最大の工学的課題であった。打ち上げ約2週間後の2月24日から28日にかけてアンテナ展開実験を行い, 展開に成功した。本稿は「はるか」のアンテナ展開実験を, 衛星システム全体としてのオペレーションの観点から詳述するものである。<br />The paper describes details of the antenna deploy experiment of the scientific satellite HALCA conducted on 24 to 28,February 1997. HALCA was launched on 12 February 1997 by the ISAS's new rocket M-V for the purpose of engineering experiments on the technologies necessary for space VLBI and radio astronomical observations by space VLBI. HALCA has been designed as an orbiting radio telescope, and deployment of a parabolic antenna with an effective aperture diameter of 8 meters, the aperture of which is made of molybdenum mesh and a tremendous number of cables, was the largest engineering challenge in the HALCA's engineering experiments. The deploy of the antenna was successfully conducted following an operational sequence carefully of the antenna was successfully conducted following an operational sequence carefully designed and prepared. The success of the antenna deployment has opened a way towards the successful space VLBI experiments that HALCA has conducted since the first reception of a signal from a celestial radio source on 24 March 1997.<br />資料番号: SA0165948000
