A brief overview of TUM student satellites MOVE Satellites

Abstract

Since 2013 the Technical University of Munich works together with students on LEO satellite projects. With FIRST-MOVE the chair for astronautics launched the first cubesat. The development for MOVE-II started in 2014 with the students also joining the management team. 2018 and 2019 marked successful launches of MOVE-II and MOVE-IIb satellites. Currently the students of the scientific work group for rocketry and space flight (WARR) work on MOVE-III. To work with an international student group of up to 100 people at a time presents problems that have to be overcome for a successful launch. This talk will present the challenges of the development and in-orbit operations of these satellites and will give a small look into the future of TUM satellites.

Goal: Built a satellite bus for future missions
which only needs minor adjustments
Main Design Objective:
„No matter what, MOVE shall create and deliver
data!”
Highest Design Goal:
“Robustness rather than Efficiency”
-> Famous last words

After 2 weeks deployment and successful
communications:
No data beacons
Only CW beacon every 60 sec
Propably software damage
Possible scenario:
Hard power reset
Errors during write operation
Booting not possible anymore
