Advanced Orbiting System (aos) For A Space Laboratory Validation Program Design And Implementation,

Based on the background of future space station needs, and refering to the "System Project Design of Space Station 's AOS", this paper discusses and researches the system structure, system data stream, critical devices's design criterion and data format, primarily analyses and researches Link-Controller's function and corresponding service data format, puts forward a scheme of data processing and transmiting which according to AOS system, designs and implements a demo validating system of AOS.The system primarily proves it is feasible that we realize Link-Controller function on VxWorks. Its primary tasks are data packing, net tranporting, data processing, data unpacking and dynamic displaying to space customers' data according to AOS system, and designing the data format and data processing ways of packages such as CCSDS, M-PDU, VCDU which apply space data transmiting. Finally, it proves that the system has the characteristics of high data transmiting speed, supporting multi-customer and processing various data.BSP is needed to support VxWorks running on particular embeded computer. This paper introduces BSP's status and function in VxWorks and the relations between BSP and device's driver, and discusses development and debugging method of BSP. and it also discusses how to build a development environment customize BSP.
