Electrically, the spacecraft is configured in four major functional areas:
- Power-supply subsystem, including a pyrotechnics unit
- On-board data-handling subsystem
- Attitude and orbit control and measurement subsystem
- Telecommunications subsystem.
Dedicated, physically separated and carefully shielded harnesses interconnect the various subsystem and payload units. The payload includes a separate experiment interconnection harness.
