The pioneering Multi-Gigabit Rate Radiation Hard Bus supporting an open system architecture will dramatically speed-up the development of commercial space data-processing and telecommunication systems that require gigabit data rates and low power consumption. Possible commercial areas include serializer/deserializer products, analog-to-digital converters, switching fabrics, etc. The high radiation tolerance of the proposed technology makes it also suitable for NASA and commercial space applications. Plug-and-Play Multi-Gigabit Rate Radiation Hard Bus supporting an open system architecture capable to operate at extreme temperatures and radiation environment of deep space will be also highly beneficial for the success of NASA's Constellation projects that are designed to leave low-earth orbit (Orion, Ares V Earth Departure Stage, Altair, Lunar Surface Systems, EVA suits, etc.). It will speed up the development of avionic systems with high performance, flexibility and reliability critical for those projects.
