Payload Data Handling System
The PDH is a dedicated computer system responsible for the high level command distribution and the science data collection between all payloads at the satellite. The PDH has data interfaces to all payloads, the spacecraft bus computer (SBC) and the down-link telemetry channel. The tasks of the PDH can be divided into three groups :
Furthermore, several technological experiments will be carried out at the PDH. It will be tested the on-board geo-coding facility, different classification algorithms as well as miscellaneous technical approaches, like fiber optic interconnects, high density multi-chip modules or on-line real-time parallel processing.
