TUBIN - Dataset of Satellite Telemetry during VLEO and Re-Entry

Introduction

TUBIN  was a university satellite mission of the Chair of Space Technology at Technische Universität Berlin with the objective to demonstrate novel Earth remote sensing technologies for nanosatellites. It was launched into a Sun-synchronize orbit (SSO) on 2021-06-30 and re-entered Earth's atmosphere on 2025-12-16.

More information about the TUBIN mission can be found on the website: TU Berlin - Chair of Space Technology - TUBIN mission

Background on Data Collection

The data provided in this data set is from the end of TUBIN's orbital lifetime, specifally from the 2025-05-01 when TUBIN's altitude decreased below 400 km until the re-entry on 2025-12-16. While selecting the telemetry provided a focus was laid on the telemetry most relevant for future VLEO missions. Other telemetry might be available, please reach out if you are missing telemetry from a specific subsystem.

# 数据采集背景
本数据集提供的数据取自TUBIN在轨寿命末期，具体时段为2025年5月1日（其轨道高度降至400公里以下）至2025年12月16日任务再入大气层期间。在选取遥测（telemetry）数据时，我们优先挑选了与未来极轨超低轨道（VLEO）任务相关度最高的遥测数据。本数据集可能未涵盖全部遥测数据，若您需要特定子系统的遥测数据，请与我们联系。
