A Combined Data and Power Management Infrastructure

Beschreibung

In 2009 the need for a suitable onboard computer design arose for the small satellite project at the Institute of Space Systems, University of Stuttgart, Germany. It had to meet the constraints imposed by the small satellite (a 130 kg CubeSat) with its full featured ACS, diverse payloads and full CCSDS telecommand and telemetry standard compliance.The design of the Onboard Computer system lead to a functional merging between onboard computer components and the satellite's Power Control and Distribution Unit, resulting in a very innovative solution – the so-called Combined Data and Power Management Infrastructure. The technical implementation of such a design was achieved with the support of an international industry partner consortium consisting of Astrium GmbH, Aeroflex Colorado Springs Inc., 4Links Ltd., Aeroflex Gaisler AB, Vectronic Aerospace GmbH and HEMA Kabeltechnik GmbH & Co. KG.At end of the flight unit's development the consortium decided to provide a single consistent documentation of the developed CDPI Infrastructure. The technical overview should be available for other university students in a sort of mix between technical brochure and user guide. This book also might be of interest for future university or industry partners who intend to order rebuilds / adaptations of the CDPI infrastructure or even the entire satellite bus in Stuttgart for their missions.
This book describes the development and design of a unique combined data and power management infrastructure The use in small satellites gives some particular requirements to the systems like potential hardware failure robustness and handling of different types of external analog and digital interfaces. These requirements lead to a functional merge between On Board Computer and the satellite's Power Control and Distribution Unit, which results in a very innovative design and even a patent affiliation. This book provides system engineers and university students with the technical knowledge as mix between technical brochure and a user guide.

Gives details on the development background to estimate the overall system's function, performance and usability for satellite missions

From the reviews:

“The text is organized into ten chapters, written by a total of 20 individual authors. Each chapter addresses the functionality and design of a particular modular circuit board … . this text is recommended as a reference and guide to students of small-scale satellite design, and to practitioners who actually build and operate such satellites, for whom these cutting-edge modular design approaches would be advantageous.” (A. G. Larson, Computing Reviews, November, 2013)
