Jämförelsen mål är att få reda på vilken eller vilka av standarderna som är bäst lämpade för framtida rymdapplikationer. Förutom detta har också ett testsystem för en av standarderna (MIL-STD-1553) byggts upp med hjälp av FPGA teknologi. Examensarbetet utfördes i samarbete med Contraves Space AG i Zürich, Schweiz.

The aim was to perform an analysis of 12 spacecraft interface standards and to construct a simple breadboard, which should work as a test system. The conclusion of the extensive analysis is that SpaceWire, MIL-STD-1553 and CAN are the most interesting interfaces for future data communication in spacecrafts. In the breadboard part of the work, a test system was built and data gathered with help from a demonstration program that came with one of the components. PREFACE This report is a result of a thesis work done for Linköping University at Contraves Space AG in Zürich, Switzerland. I would like to thank all people from Contraves Space AG who have helped me with technical support and material. A special thanks to my supervisor at Contraves Space Hans-Jakob Schneider and my professor Shaofang Gong. I would also like to direct a personal thanks to Teresa Braun at Contraves Space who proofread the paper. Last, but not least, my family. I would like to thank them for their support during my studies and for helping me reaching my goals.
