At the end of this very successful and busy year we have been rewarded with smoothly running test campaigns and highly satisfying test results. Between 11th and 18th December, the LuxSpace ESAIL team successfully performed the environmental qualification for its in-house development products: the ADCS I/F (Attitude Determination and Control System Interface Unit) and the RPU (Release Power Unit). The ADCS I/F Unit is in charge to interface the on-board computer with all the sensors and actuators needed to ensure the satellite pointing. The RPU has the objective to trigger the release of the solar panels and the payload antennas. Both units were undergoing mechanical testing, compound of different vibration tests (quasi-static, sine and random) and shock on all the units’ axes. These tests proved the survivability of the units to the mechanical loads due to launch and the separation of the upper stage. Furthermore, one of the ADCS I/F underwent thermal test in the Thermal vacuum (TVAC) chamber, proving that the unit can survive to deep space within a temperature range between -30 and +60°C. The unit housekeeping was monitored along the full 3-days testing while cycling its temperature from hot to cold (and vice-versa).

In parallel to these unit-level environmental qualifications, the LuxSpace ESAIL team successfully performed the vibration qualification of the satellite structure and the solar array subsystem with the full scale structural model (SM). We are proud to finish this year with such achievements and look forward to the upcoming activities in 2018!
