Study on autonomous and distributed time synchronization method for formation UAVs

In order to implement high precision time synchronization autonomously in the absence of any external time source, in this paper, the author introduced the synchronize model of fireflies into UAV formation network, and proposed a kind of distributed time synchronization method base on broadcast, and conducted some computer simulation experiments and built one test platform to prove the feasibility of the method and its performance, the results show that the method can effectively achieve time synchronization autonomously without any external time source, and the synchronization accuracy can be achieved about 50us.
