轨道碎片累积威胁太空活动可持续性，亟需突破现有依赖燃料的主动清除方法。本文提出一种新型清理架构，集成机械夹持系统以稳固捕获目标，并采用高效率太阳能供电的NASA进化型氙离子推进器（NEXT）及自主导航协议。高保真仿真验证了该架构性能：成功实现从800公里到100公里的逆轨道脱轨，雷达基扩展卡尔曼滤波（EKF）导航定位均方根误差（RMSE）低于10米，且在1秒内通过延迟/中断容错网络（DTN）协议实现93%的数据交付效率。该方案显著推动轨道管理发展，确立了可再生能源推进的新基准，大幅降低对传统燃料依赖，延长多目标清除任务寿命。
原文摘要 · Abstract (English)
The escalating accumulation of orbital debris threatens the sustainability of space operations, necessitating active removal solutions that overcome the limitations of current fuel-dependent methods. To address this, this study introduces a novel remediation architecture that integrates a mechanical clamping system for secure capture with a high-efficiency, solar-powered NASA Evolutionary Xenon Thruster (NEXT) and autonomous navigation protocols. High-fidelity simulations validate the architecture's capabilities, demonstrating a successful retrograde deorbit from 800 km to 100 km, <10m position Root Mean Square Errors (RMSE) via radar-based Extended Kalman Filter (EKF) navigation, and a 93\% data delivery efficiency within 1 second using Delay/Disruption Tolerant Network (DTN) protocols. This approach significantly advances orbital management by establishing a benchmark for renewable solar propulsion that minimizes reliance on conventional fuels and extends mission longevity for multi-target removal.
