Abstract:

In order to solve the problem that the traditional single leader-follower relative navigation structure leads to the divergence of navigation accuracy due to leader failure and the heavy computation and communication burden of the fully connected cooperative navigation algorithm, and improve the stability of swarm navigation and the utilization of navigation information, a hierarchical cooperative navigation algorithm is proposed based on the federal filtering algorithm.The unmanned aerial vehicle (UAV) swarm is divided into two groups according to the navigation accuracy. The UAV swarm hierarchical cooperative navigation model is established in the leader layer and follower layer. The simulation results show that the hierarchical cooperative navigation algorithm has a better navigation accuracy than the traditional single leader-follower cooperative navigation algorithm; to a certain extent, increasing the proportion of the leader in the swarm can improve the navigation performance of the swarm; and when the leader fails, it has better fault tolerance and good stability.

Key words: unmanned aerial vehicle (UAV) swarm, federated filtering, navigation, hierarchical cooperative
