TTEthernet for launch vehicle communication network

Abstract

In the paper, we research on the application of TTEthernet in the launch vehicle control system. Firstly, the communication network requirements of next generation launch vehicle is proposed in this paper. Then, we introduce the TTEthernet in the view of the mechanism of network communication, clock synchronization and fault-tolerant performance. And further, we analyze the application advantages of TTEthernet. Lastly, we design a dual redundant communication network topology for launch vehicle based on TTEthernet, studying the dataflow of the communication network during the process of vehicle launching. The results can not only show the TTEthernet exploration in launch vehicle, but also provide a guideline for TTEthernet research in the field of space application.
