High speed communication buses are necessary for satellites and spacecrafts. In this paper, traditional buses such as FDDI, ISO 8802-4, and some new techniques, such as SFODB, RPR and AFDX.are briefly introduced. The comparisons between these buses are discussed. The topology, cable and characters of these protocols are analyzed. And from the comparison, it can be seen that SFODB, AFDX and RPR may be good candidates for the new generation of spacecraft buses in the future.

SUMMARYAerospace remote-sensing payloads are continuing to advance to higher speeds and increasing the demands of on-board intra-satellite networks. These payloads include synchronous continuous mode and asynchronous event-driven sensor data requiring real-time transfer with deterministic latency to capture sensor data. The networked satellite payloads include combinations of: uplinks, downlinks, sensors, processors, formatters, storage devices (recorders), and payload controller. Advanced systems planned for development in the next few years require data rates of 1-10 Gbps. An effective aerospace data-handling network must supply real-time data that is fault tolerant and able to withstand the rigorous conditions of launch as well as the harsh space environment. The IEEE1393-1999 Standard for spaceborne fibre-optic data bus (SFODB) has established the design requirements for the interconnection of these on-board aerospace subsystems. Programs involving NASA Goddard Space Flight Center, the Air Force Research Laboratories, Space Photonics Incorporated, the University of Arkansas, and others, are in the process of developing components necessary for the implementation of the SFODB. SFODB utilizes fibre-optic components for subsystem interconnect and eliminates cable-to-cable and box-to-box EMI, significant reductions in size, weight, and power are among the achievable characteristics that are desirable for aerospace applications. This paper discusses SFODB characteristics and the status of implementation programs.

The application of high speed data bus on the satellites having several remote sensors could not only satisfy the demand of high speed data transfer, but also could reuse the equipment at both the component and subsystem levels for other space missions, thus reducing the costs of on-board processing system integration. In this article, a special high speed data bus with simple interfaces is chosen for transferring the data produced by remote sensors and other instrumentations. First, the function and the structure of the data bus are discussed carefully. And then, the bus controller, which is a key module of the data bus, is designed. At last, the function and performance of the bus controller are verified by VHDL simulation.spaceborne, data bus, VHDL
