标题： Recoil-Constrained Scheduling of Non-Propulsive Payload Deployment for Mega-Constellations

摘要： 本文解决了在低地球轨道巨型星座非推进载荷部署过程中后坐动量累积的重要挑战。 引入了一种高效的基于相位的近似算法，使得计算速度提高了90%以上，同时保持最大释放速度误差低于1%。 分析表明，累积后坐速度是决定部署能力的主要因素，过剩速度大约是累积后坐速度的一半。 推导出一个用于预测最大释放速度的解析表达式，使任务规划快速进行，误差小于2%。 该框架确定了关于高度差、质量比和部署数量的操作边界，适用于近地轨道（最高2,000公里），为未来每轨道平面包含超过200颗卫星的星座的可持续服务提供了重要工具。 显示英文摘要

摘要： This paper addresses the significant challenge of recoil momentum accumulation during non-propulsive payload deployment for low-Earth-orbit mega-constellations. An efficient phase-based approximation algorithm is introduced, leading to over 90% faster computation while maintaining maximum ejection velocity errors below 1%. The analysis highlights that cumulative recoil velocity is the primary factor governing deployment capability, with excess velocity being approximately half of the cumulative recoil velocity. An analytical expression for predicting the maximum ejection velocity is derived, enabling rapid mission planning with less than 2% error. This framework establishes crucial operational boundaries concerning altitude differences, mass ratios, and deployment quantities for near-Earth orbits (up to 2,000 km), providing essential tools for the sustainable servicing of future constellations comprising over 200 satellites per orbital plane.
