摘　　要：当前空间通信的发展趋势是空间通信网与地面通信网融合,建立天地一体化的信息传输系统。针对天地一体化信息传输系统中IP over CCSDS网关中的协议转换技术开展研究,参考了IP over CCSDS Space Links等相关建议,在Linux内核的网络协议栈中实现了IP协议与CCSDS AOS空间数据链路协议的相互转换,并通过试验对在CCSDS-AOS空间数据链路之上进行IP传输进行了测试与验证,表明了利用IP over CCSDS网关构建天地一体化信息传输系统的可行性,并给出了工程应用的实现建议。The construction of an integrated space to ground data transmission system fusing the space and terrestrial communication networks is the trend of space communication. Study on the protocol conversion of IP over CCSDS gateway in integrated space to ground data transmission system is conducted. According to CCSDS red book ＂IP over CCSDS Space Links＂, IP and CCSDS AOS protocol conversion is implemented in TCP/IP stack of Linux kernel. Test and evaluation of IP transferring over CCSDS AOS space data links are carried out in experiments, and feasibility of constructing an integrated space to ground data transmission system through IP over CCSDS gateway is verified. Suggestions for engineering application are put forward as well.
