摘　　要：自从Space X公司提出建设基于低轨小卫星的Wi-Fi卫星通信系统,引起一场研究热潮,主要关注可实现性,实现复杂度,卫星建设成本等问题。文中讨论了低轨卫星实现Wi-Fi卫星通信存在的问题,提出基于高轨卫星的Wi-Fi卫星通信系统。为验证其可行性,设计一个地面卫星链路验证系统,采用内嵌ARM核的Zed Board开发平台模拟地面站,分别通过Gbit网口连接以太网传输数据,两个模拟地面站使用SPI接口连接,SPI接口模拟地面与卫星的上下行链路。通过理论分析及验证系统模拟实现,证明基于高轨卫星的Wi-Fi卫星通信系统的可实现性。Since the SpaceX company made construction LEO satellites Wi-Fi satellite-based communication system,causing a boom in research,focusing on realizing, implementation complexity, satellite construction costs and other issues. This article discusses the problems of realizing Wi-Fi LEO satellite communication and then raised Wi-Fi high orbit satellite communication system based on satellites. In order to verify it＇s the feasibility, it designs a ground satellite link verification system that uses embedded ARM core development platform simulation ZedBoard ground stations are connected via Ethernet port Gbit Ethernet transmission data, two analog ground stations using the SPI interface, SPI Interface analogue terrestrial and satellite uplink and downlink. Through the theoretical analysis and simulation verification system implementation, proof can be realized based on high-orbit satellites Wi-Fi satellite communication system.
