As the military electronic system demands more and more the real-time and certainty of the network， FC-AE-1553, as a command response network protocol based on fibre channel with strong real-time and high certainty, has been more and more widely used in the fields of data transmission and flight control in avionics environment. This paper introduces the basic characteristics of FC-AE-1553 bus, then takes the launch vehicle telemetry system as the background, constructs a simple star network topology, and uses FC-AE-1553 bus protocol as the communication carrier to verify the applicability of FC-AE-1553 bus technology in the launch vehicle telemetry system.
