为解决传统卫星设计中有线连接带来的各种问题,提出了一种基于无线网络技术的卫星平台系统方案。该方案以嵌入式系统级芯片处理器及射频集成电路作为基本通信单元,进行了以星载计算机为核心的无线网络卫星平台结构的设计,集星务管理、任务管理和设备管理于一体的无线网络卫星通信协议的设计,星载计算机与其他分系统、部件和单元之间均采用无线方式进行数据交互,实现了无线网络卫星自主管理和即插即用,支持卫星的快速测试、快速集成和装配。通过无线网络:卫星平台原型系统软硬件设计、实现及测试,验证了无线卫星平台的可行性和设计的正确性、有效性。
To solve various problems brought by wire connection in traditional satellite design, a kind of satellite elec- tric platform system scheme based on wireless network technology was proposed. The System on Chip (soc) proces- sor and Radio Frequency Integrate Circuit (RFIC) was used as basic communication unit in this scheme, and the wireless satellite network platform was designed by taking onboard computer as the core. The design of wireless sat- ellite network protocol which integrated satellite keeping, task management and equipment management was put for- ward. The wireless way was used to interact data between onboard computer and other subsystems, parts and units, thus the task self-management technology as well as plug and play were realized. It supported fast test technology, fast integration and assembly of satellite. Through design, realization and test of software hardware in wireless sat- ellite platform system prototype, the validity and effectiveness o{ wireless satellite platform were verified.
