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. The spacecrafts share the same orbital and body frame of reference in V1.0.1.
