卫星通信高速数据传输系统设计

摘要

This paper designs a transmitting system which is available in satellite communication. This system is based on Virtex-5 Field Programmable Gata Array(FPGA). It consists of PCI Express bus and optical communication module based on Aurora protocol. This system has the character of sending and receiving simultaneously for bidirectional I/O. Test result shows that the system achieves that the eight channels of PCI Express, and optical communication can works in real time data communication at a high-speed of 1.25 Gb/s. The system can effectively simulate the satellite data download as well as the remote control of the ground stations towards satellite.%设计一种用于卫星通信的高速数据传输系统.该系统采用Virtex-5系列现场可编程门阵列,由PCI Express通信模块和基于Aurora协议的光纤通信模块组成,具有双单工同时收发的特点.测试结果表明,该系统的PCI Express通信模块可实现8路通道工作模式,光纤通信模块的数据传输速率达到1.25 Gb/s,能有效模拟星载数据的下发和地面站对卫星的遥控.
