On Friday, one of the first jobs was to position the satellite on the tilting table in preparation for testing. We also unpacked and set up the electrical ground support equipment in the ‘checkout room’.
Some team members from ESA and Thales Alenia Space went to the launch pad and to the ‘S3B’ building in preparation to validate communication links.
The satellite is currently in the S5C building. The launch pad and the S3B building, where the satellite will be fuelled and mated with the launcher’s Fregat upper stage and encapsulated in the fairing, are actually a few kilometres away.

It is therefore important to make sure that communication links between these locations work to make sure the satellite can be commanded from the electrical ground support equipment, which will remain in S5C.
Then we switched the satellite on – the first ...
