The latter then activates platform AOCS units to achieve a stable SC safe-mode attitude acquisition and potential ground contact through activation of the transceivers. As summary in these cases reboot and configuration are initiated by the PCDU controller and again PCDU controller and Reconfiguration Unit together manage the recovery. 2 Innovation: A Combined-Controller for all FDIR Functions In a classic unit architecture on board three controllers implement the functionality, namely the OBC’s Reconfiguration Unit [10] and as subunit the OBC’s Command Pulse Decoding Unit (CPDU) [10] as well as the PCDU’s internal controller IC.

All of these requirements are important and are considered very carefully before a processor is chosen for any satellite program. For the FLP satellite’s OBC Processor-Board, the Aeroflex UT699 LEON3FT processor was chosen (Fig. 3). This processor is highly suited for satellite applications based on all of the above criteria. The LEON3FT is a 32 bit SPARCTM V8 device with many interfaces suitable for multiple types of implementations. For the FLP satellite program, it was decided at the program level to use SpaceWire as the primary interface between all of the boards in the OBC unit.

Details on this card can be found in Sect. 1. 2 The OBC Processor-Boards 41 The Ethernet interface on the LEON3FT is implemented by routing the signals from the LEON3FT to the 44 pin D-sub connector. During debug the user will use the DSU/Ethernet Interface card to implement the Ethernet connection. The LEON3FT microprocessor on the OBC Processor-Board also has a Debug Support Unit (DSU) on the device and these signals are routed on the SBC to the 44 pin D-sub connector. When attempting to access the DSU, the user will use the DSU/Ethernet Interface card.
