面向网络感知的近地轨道卫星变轨策略分析数据集

本数据集面向网络感知的近地轨道卫星变轨策略研究，由论文 A First Look at Networking-Aware LEO Maneuvers 的实验数据整理形成。数据来源于Starlink星座的公开TLE轨道数据，采用Python计算与解析生成，并覆盖2023-02至2024-04等时段。数据重点记录卫星轨道高度、同轨邻居相对距离、星间链路断裂频率与由此导致的路由故障比例，并区分必要/非必要变轨对网络拓扑的影响。数据集包含说明文档与1个Excel文件（内含10个子数据与对应图表），内容涉及单颗卫星星与邻星距离序列、按小时星间链路断裂统计、变轨造成的潜在与实际星间链路断裂数量、路由故障占比、典型卫星个例对比等。该资源旨在支撑天地一体化网络稳定性评估与变轨策略优化，为研究者识别变轨对星间链路与路由性能的真实影响提供可复现实证依据。数据规模约1.6MB，完全共享，可直接用于再分析与方法复现。This dataset is developed for research on networking-aware low Earth orbit (LEO) satellite maneuver strategies, and is compiled from the experimental data of the paper *A First Look at Networking-Aware LEO Maneuvers*. The data is sourced from the public Two-Line Element (TLE) orbital data of the Starlink constellation, generated via Python-based computation and parsing, and covers the period from February 2023 to April 2024 and other relevant timeframes. The dataset primarily records satellite orbital altitude, relative distance between co-planar neighboring satellites, inter-satellite link (ISL) breakage frequency, and the proportion of routing faults caused thereby, as well as differentiates the impacts of mandatory and non-mandatory orbital maneuvers on network topologies. The dataset includes an instruction document and one Excel file containing 10 sub-datasets and corresponding charts. Its contents cover the distance sequences between a single satellite and its neighbors, hourly inter-satellite link breakage statistics, the number of potential and actual inter-satellite link breakages caused by orbital maneuvers, the proportion of routing faults, comparisons of typical satellite cases, and other related content. This resource aims to support the stability evaluation of space-ground integrated networks and the optimization of orbital maneuver strategies, providing reproducible empirical evidence for researchers to identify the actual impacts of orbital maneuvers on inter-satellite link and routing performance. The dataset has a size of approximately 1.6 MB, is fully shared, and can be directly used for re-analysis and method reproduction.
