u1i/iss-position-snapshots

该数据集包含超过145万条国际空间站(ISS)轨道位置的原始遥测快照，时间跨度为2021年9月至2026年4月(约5年)。特别适用于轨道力学建模、异常检测(如识别轨道推进、衰减峰值或对接机动)和时间序列预测等任务。数据集按月打包为zip文件(如ISS_data_2021-09.zip)，内部按日期组织子目录，每个时间点的数据以JSON格式存储在单独的txt文件中。需要注意的是，由于实际采集过程中的硬件限制，数据存在若干缺失时段。

This dataset contains over 1.45 million raw telemetry snapshots of the International Space Stations (ISS) orbital position, collected over a span of roughly 5 years (September 2021 through April 2026). It is particularly useful for tasks involving orbital mechanics modeling, anomaly detection (e.g., identifying orbital boosts, decay spikes, or docking maneuvers), and time-series forecasting. The dataset is distributed as monthly .zip archives (e.g., ISS_data_2021-09.zip), with data organized into subdirectories by day, and each individual reading stored as a .txt file in JSON format. Note that there are several periods of missing data due to hardware limitations during actual collection.
