NCKU-CSRDC CubeSat Thermal Telemetry Dataset: Multi-Satellite In-Orbit Temperature Measurements

This is a database that contains thermal telemetries of four CubeSats from NCKU-CSRDC: IRIS-A, Lilium-1, Lilium-2, and Lilium-3. The files are organized as follows: Beacons: telemetries acquired in real time from spacecraft in LEO collected by the ground station at NCKU (Guiren Campus), twice a day, during the contact windows, roughly at 10:00 and 22:00. These were collected over several months during their lifetime. Full Orbit Data: telemetries acquired by the spacecraft and saved in their internal memory over a full orbital period. These were collected every 10 seconds and eventually downloaded by the ground station at NCKU (Guiren Campus). Notes: All times are UTC+0. All temperatures are in Celcius. The beacon telemetries for Lilium-1 are split before and after a complete magnetometer anomaly, so they are presented in the period of time of steady flight and in spinning state. Likewise, a full orbital period was recorded when flying in a steady state and then again after it was in this spinning state. The beacon telemetries for Lilium-2 and Lilium-3 are collected in several beacon structures, so the temperature in different subsystems is collected separately. These structures were correlated within a radius of 5 seconds; some temperature telemetries are missing for the ADCS measurements. All times are presented in this database along with the corresponding time difference between the measurements (1-5 seconds). For a better understanding of the attitude at which the CubeSats were orbiting LEO, please find the corresponding diagrams in the published paper.
