Pictured here is the ExoMars 2016 Trace Gas Orbiter (TGO) core module during integration of its electrical subsystems at Thales Alenia Space, Cannes, France in November 2014. The lower (square) part of the core module is the service module, which houses the majority of the non-instrument subsystems. In the left foreground a gold-coloured box can be seen; this is the power conditioning unit (PCU), which takes the electrical power generated by the solar arrays and makes it suitable for charging the spacecraft battery and powering the payload. The battery will be mounted behind (in this configuration) the PCU; the PCU/battery panel hinges up into the service module once integration is complete. The power control and distribution unit (PCDU), which controls the delivery of electrical power to all of the spacecraft subsystems, is behind the panel labelled ZP1.
