Application ofIRIG-B code in time synchronization system

Currently,more and more system is composed by a number of subsystems which are distributed in different locations.Achieving time synchronization of each subsystem is an important study.For achieving time synchronization between two platforms,using time two-way transfer method,in this method,two platforms must transfer information to achieve time synchronization.IRIG-B code is adopted as a code which is used for time transfer in time two-way transfer.The FPGA can be used to achieve a coding and decoding of IRIG-B code,which has more virtue than traditional method: occupied resource is less,language structure is simple and easy to implement,and precision of IRIG-B code is high.
