Multi-Mission Operations at Technische Universität Berlin through the example of TUBIN

Abstract

The chair of space technology of Technische Universität Berlin has a long heritage of designing, manufacturing and operating small satellites. Starting with the launch of TUBSATA in 1991 up to the launch of TUBIN in 2021, a total of 27 satellites in the range of 375 g to 56 kg were successfully developed. To date, 20 of these satellite remain operational and are contacted on a regular basis. The utilized frequencies are in the p band, s band and x band ranges. To accommodate simultaneous operation of these missions, the primary ground station at Technische Universität Berlin is equipped with a set of different antennas and transceiver paths. The setup utilized for TUBIN is outlined and through the example of its first 12 months in orbit, mission operations at Technische Universität Berlin are analyzed, highlighting various milestones met during its nominal lifetime.
