After the mechanical integration of the ECLAIRs and MXT instruments, it’s time for the electrical integrations, with the connection of the harnesses of the French instruments to their respective control boxes.
Once the instruments have been connected, the payload module can be closed by very carefully approaching the side panels. Once the panels are closed, the ECLAIRS and MXT instruments are tested to ensure that they are in good health. These tests conclude the whole integration activity by confirming that everything is properly wired and functional.
Now it’s time to move on to the next stage in this long sequence, the environmental tests, starting with the electromagnetic compatibility tests, during which we check that the instruments are not disturbed or do not disturb the other equipment on the satellite when everything is operating.
