This ebook describes the advance and layout of a different mixed info and tool administration infrastructure The use in small satellites supplies a few specific requisites to the structures like strength failure robustness and dealing with of other forms of exterior analog and electronic interfaces. those necessities result in a useful merge among On Board desktop and the satellite's strength keep an eye on and Distribution Unit, which ends up in a truly leading edge layout or even a patent association. This booklet presents procedure engineers and collage scholars with the technical wisdom as combine among technical brochure and a person guide.

Sample text

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. 3 V ± 5 % input power. In addition there are five MDM 9 pin connectors, 4 of which are for SpaceWire interfaces and one for RS422. The SBC consumes a maximum of no more than 5w at full throughput. 9 Mechanical Design and Dimensions The SBC is based on a 3U cPCI Printed Circuit Board (PCB).

With increasing power availability the PCDU subsequently activates further S/C platform units, first unit being the OBC, respectively in Safe Mode the redundant OBC (depending on the latest settings in the Reconfiguration Unit). 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.

Determinacy is the ability of a computer system to calculate with great accuracy the response time of any given process. Most satellite implementations of processors require the tasks performed by the processor to be very deterministic. 3 Technical Overview The OBC Processor-Board is a Single Board Computer (SBC) that is designed to perform the main processor function within the OBC system. The board is designed and implemented based on requirements passed down from the University of Stuttgart to Aeroflex Colorado Springs.
