Application of TTE Bus Technology in Launch Vehicle Telemetry System

With the gradual development of the manned lunar landing program, the new generation of launch vehicles is undertaking arduous tasks, in which the telemetry system of the launch vehicle plays a vital role in flight test and data acquisition. TTE (Time-triggered Ethernet) bus technology has gradually become an ideal choice for launch vehicle telemetry system because of its high reliability, real-time and flexibility. This paper discusses the basic principle of TTE bus technology and its specific application in telemetry system, and compares it with traditional telemetry system. Obviously, TTE bus technology not only improves the efficiency of data transmission, but also enhances the fault tolerance of the system, which provides strong support for the system control of the launch vehicle and the accurate data acquisition of each equipment. The research results show that TTE bus technology has broad application prospects in future aerospace missions.
