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.
