SPOT 6 and SPOT 7 satellites in the clean room


The story begins in late November 2010 with the arrival of SPOT 6’s mechanical structure at Astrium’s clean room in Toulouse.

 SPOT 6 - Preparation of structure

December 2010 - Preparation of SPOT 6’s structure
The hexagonal-shaped bus structure, modelled on a honeycomb, offers optimal compactness and stiffness.

SPOT 6 - Wiring of the bus

January 2011 - Wiring of the SPOT 6 bus
The bus opens out on all six sides to allow easily installation of equipment.

SPOT 6 - Integration of the propulsion module

February 2011 - Integration of the propulsion module
The hydrazine propellant tank and thrusters are integrated in the mechanical structure.

SPOT 6 - Equipment assembly

February to September 2011 - Equipment assembly
Equipment and systems are assembled on the bus and tested.

SPOT 6 - Instrument-bus join

September 2011 - Instrument-bus join
The SPOT 6 instrument is hoisted above the bus and then lowered gently for connection.
