摘　　要：针对天基系统星上处理能力不足、技术落后、无法实现多源数据在轨实时处理等难题,本文提出一个应用于中低轨微小卫星的天基网络化通用服务平台的设计概念,为现在的卫星技术发展提供新的硬件架构,同时异构的体系结构既可以实现星上的独立运行,又可以为星载计算机的数据处理提供硬件加速.本文主要介绍天基网络化通用服务平台的硬件设计,包括芯片选型、对外关系以及所需的存储容量和为实现接口的兼容性,在FPGA上设计实现了MIL-STD-1553B总线的总线控制器向远程终端发送数据的相关模块.For the lack of processing power and backward technology, satellites cannot achieve real-time processing of multi-source data in orbit in the space-based system, so this paper presents a design of a space-based network universal service platform for micro satellites in the medium and low orbit. This design provides a new hardware architecture for the development of current satellite technology. At the same time, this heterogeneous architecture cannot only achieve the independent operation of the satellites, but it can also provide hardware acceleration for the data processing of the onboard computers. This paper mainly introduces the hardware design of space-based network universal service platform, including chip selection, external relations, and the required storage capacity. In order to realize the compatibility of the interface, the module of the MIL-STD-1553B bus is designed and implemented on the FPGA to send data from the bus controller to the remote terminal.
