|  | The Payload Module (PLM) provides the main supporting structure for both the payload instruments and the payload support systems. Instrument sensors and antennae are mounted on the external panels, while most of the electronic units are accommodated inside the PLM.
The accommodation of the large suite of instruments is a significant design driver for the overall PLM configuration. The PLM also houses all of the avionics necessary for power regulation and distribution, command and control, and the handling of scientific data. |
