论文摘要
提出了一种快速估计去除低地球轨道碎屑的转移成本的方法。考虑到具有相似倾斜度值的人群中的碎屑对象。提出的近似分析可以提供任何碎屑对象对之间的实际deltav估计,这是时间的函数。这些估计可以快速评估要去除大量目标的成本。地球无扰动的影响(J2)被利用以降低转移成本。全球轨迹优化竞争第9版的碎片清除问题用于评估估计准确性。通过将其与JPL获胜团队提出的GTOC9解决方案进行比较,可以验证对对象对之间传输的估计。结果的比较证明了简单近似值的非常好的精度。关键词:太空碎片;近似;轨迹优化; J2扰动
A method for the rapid estimation of transfer costs for the removal of debris in low Earth orbit is proposed. Debris objects among a population with similar inclination values are considered. The proposed approximate analysis can provide estimations of actual Deltav between any debris object pair as a function of time; these estimations allow for the rapid evaluation of the costs of large sequences of targets to be removed. The effect of Earth's oblateness perturbation (J2) is exploited to reduce transfer costs. The debris removal problem of the 9th edition of the Global Trajectory Optimization Competition is used to evaluate the estimation accuracy; Deltav estimations of the transfers between objects pairs are verified by comparing them with the GTOC9 solution proposed by the winning team from JPL. The comparison of the results demonstrates the very good accuracy of the simple approximation. Key words: Space debris; approximation; trajectory optimization; J2 perturbation
