Research on Spaceflight TT&C Ground System Data Exchange Pattern Based on Google Protocol Buffers

Focus on designing data exchange pattern for Spaceflight TT&C Ground System based on Google Protocol Buffers, this paper carried through research and design on related critical technology. The basic theory and using method of Protocol Buffers were introduced, encoding and decoding mechanism using Protocol Buffers were designed, TT&C data processing & transmitting pattern as well as data structure renewing & maintaining pattern were discussed, and the advantages of applying Protocol Buffers to Spaceflight TT&C Ground System data exchange area were also analyzed.
