A scientific study of the problems of digital engineering for space flight systems,
with a view to their practical solution.

2006 MAPLD International Conference

Ronald Reagan Building and International Trade Center
with a session at the Smithsonian National Air and Space Museum

Washington, D.C.

September 26-28, 2006

Seminar: Spacewire 101

The 2006 MAPLD International Conference seminars will be held on Monday, September 25, 2006 in Oceanic A & B.

Seminar Leaders:


The SpaceWire seminar will provide an in-depth study of the SpaceWire standard along with practical considerations for designs. Recent work by the SpaceWire working group will be presented, which compliments the existing standard allowing standardized method for upper level protocol development. Theoretical and real applications for SpaceWire will be discussed as well as some recently developed protocols for these applications. A group of “hot topics” will be addressed, which have implications for current and future implementations. A brief description of how SpaceWire is part of CCSDS will be presented. Concluding with the most recent work on a higher-rate version of SpaceWire called SpaceFibre that will bridge between the existing standard and a Gigabit physical level.Logistics
