While the short-term impact of collisions on missions is relatively negligible, economic models predict that in one century, space debris will be a major drag on the industry’s development. However, this challenge might also become a business opportunity, with the combined effect of the New Space and renewed legal regulations. The Recycler is a project of geostationary satellite able to harvest components of cooperative satellites. By re-purposing existing hardware, the Recycler may open a second-hand market of debris-efficient On-Orbit-Servicing (OOS). This paper provides the strategic analysis of re-purposing missions, using an approach drawn from Game Theory. This enables unique guidance on which aspects of the proposal should be the focus of attention. Starting from an economic problem, the model is gradually complexified to fit future standard Recycler’s contracts. A sensitivity analysis and a case study were performed to assess the viability of the project. It is concluded that the major obstacles of the Recycler are the number of clients reachable under its fuel constraints, the overall cost of the re-purposed components as well as the long-term rate of their degradation in the space environment.

碎片效率在轨服务:评估“回收者”GEO卫星的技术经济可行性

虽然碰撞对任务的短期影响相对可以忽略不计,但经济模型预测,在一个世纪内,空间碎片将成为该行业发展的主要拖累。然而,在新空间和更新的法律法规的共同作用下,这一挑战也可能成为商机。Recycler 是一个地球静止卫星项目,能够收集合作卫星的组件。通过重新利用现有硬件,Recycler 可以打开碎片效率在轨服务 (OOS) 的二手市场。本文使用博弈论中的方法对重新定位任务进行了战略分析。这为提案的哪些方面应成为关注焦点提供了独特的指导。从经济问题出发,该模型逐渐复杂化以适应未来的标准回收商合同。进行敏感性分析和案例研究以评估项目的可行性。得出的结论是,Recycler 的主要障碍是在其燃料限制下可达到的客户数量、重新利用组件的总体成本以及它们在太空环境中的长期退化率。
