Abstract
We report on the development of a fiberoptic physical layer bus with
RapidIO-protocol for spacecraft avionics interconnects. To emulate spacecraft
instrument data transmission, dynamic routing of real-time live camera data
packets is demonstrated through a switch-based network. For real-time instrument
data input/output, an interface bridge between Ethernet protocol and RapidIO
protocol is developed. RapidIO-based fiberoptic avionic system is compared
with 1393 ring protocol based interconnect in terms of performance, flexibility,
mass/power/size, and suitability for different mission applications. Fault
tolerant architectures for RapidIO and 1393 ring-protocol-based spacecraft
buses are also presented.
