Abstract
The first spacecraft subsystem—the Core Data Handling Subsystem (Core DHS)—is described in this chapter. As the FLP platform is based on the very innovative concept of a Combined Data and Power Management Infrastructure (CDPI) instead on the classic 3 unit design of onboard computer, power control and distribution unit and remote interface unit, this CDPI concept and its benefits are explained first. Then the chapter describes the stepwise boot process of an FLP-based spacecraft after its separation from the launcher. The last part comprises the onboard software elements and functions for control of the Core DHS subsystem.

Notes
- 1.
The latter two constraints are normally of no relevance for the LEOP boot of the satellite but for emergency recovery boots in orbit and thus according checks are included in the PCDU boot sequence.
- 2.
Magnetotorquers and magnetometers are operated in interleaved mode to avoid the magnetotorquers biasing magnetic field measurements.
