Research on Regional Coordinated Navigation and Positioning of Cluster Aircraft Based on Relative Distance

In the cooperative mission of swarm aircraft, UAV, a new tool with low cost and high efficiency, is highly flexible in location technique and covers a wide area, which can improve the success rate of the execution of the mission. However, during the process of performing missions, there is the problem of low positioning accuracy and reduced efficiency of some air vehicles due to the complexity of the environment and some unexpected factors. Therefore, this paper proposes a UAV cluster cooperative navigation and positioning method based on relative distance difference, aiming to enhance the regional cooperative navigation capability and solve the problem of position loss in areas without satellite navigation signals under unexpected situations. The solution is practically feasible after the simulation and actual test verification.
