摘要
文章设计了一种基于FPGA的符合CCSDS标准的通用码流发生器,它对外有USB、Ethernet、RS232串口和前面板设置四种不同的接口,可以对不同编译码模式进行选择设置,提供所需的CCSDS标准帧格式的信号输出,并可以检测输入信号是否符合CCSDS标准的帧格式。本设计可以适应不同型号的CCSDS标准遥测信道编码测试,在型号测控系统的地面测试中具有重要的实际应用价值。
This paper design a universal codec according to CCSDS specification based on FPGA,which have four kinds of ports, USB, Ethernet, RS232 and Front-Panel-Set. It can select proper codec model to generate desired code stream output according to CCSDS specification and detect whether the input signal correspond with given CCSDS specification. The design can adapt different telemetry channel coding test of space mission, which plays an important part in the ground test of satellite tracking telemetry and command system.
