近年，宇宙環境の急激な混雑化が進んでおり，宇宙状況把握(SSA)が国際的な課題となっている．通常宇宙ゴミ（デブリ）は，レーダ観測や光学観測により軌道把握がなされるが，地上からの視認性の悪さや機器的制約などにより，位置決定精度はせいぜい数十mオーダである．近年ではデブリへのランデブー・捕獲を行う能動的デブリ除去(ADR)も盛んに検討されている．ADRでは予めデブリの軌道・回転運動を把握している必要がある一方で，地上からデブリの回転運動を把握する技術は未確立である．飛翔体が反射器を搭載していれば，衛星レーザ測距(SLR)により数 cmオーダで軌道決定，さらに軌道決定残さから回転運動の推定が可能である．従来，反射器は特注品であり大型・高価であった．しかし，反射器が安価な市販品となれば，将来デブリとなる物体に搭載でき，軌道・回転運動の把握の一助となる．そこで，JAXA では小型・軽量・安価をコンセプトに汎用的な反射器(Mt.FUJI)の開発を2018 年度より開始した．本発表ではMt.FUJIの概要について報告する．
The dawn of space engineering development brought the rapid pollution and congestion of the space environment due to orbital debris. Therefore, space situational awareness (SSA) has become an international issue. Conventionally, orbital debris can be tracked by radar and/or optical observations. However due to poorness of their visibility from the ground and constraints of observation systems, their positioning accuracy is on the order of tens of meters at most. In recent years, active debris removal (ADR), which performs rendezvous and capture of debris, has been actively studied. Although it is necessary to grasp the orbital and rotational motion of orbital debris in advance, the techniques for grasping the rotational motion of orbital debris from the ground has not been fully established yet. If the space vehicle is equipped with one or more reflectors, it is possible to determine its orbit on the order of several cm by satellite laser ranging (SLR), and to estimate the rotational motion from the orbit determination residuals. The reflectors developed and installed in Japan and overseas were custom-made, large, and expensive. If reflectors become inexpensive commercial products, they can be mounted on objects that will become orbital debris, it will help to grasp the orbital/rotational motion. Therefore, JAXA started development of a general-purpose reflector (called Mt.FUJI) in 2018 with the concept of small size, light weight, and low cost. In this presentation, we report the overview of Mt.FUJI.
