Research on Lead Aircraft Navigation Algorithm in Cluster Aircraft Navigation

Unmanned cluster navigation technology can be divided into absolute positioning and navigation of lead aircraft and relative positioning and navigation between formations. Currently, the navigation technology for the lead aircraft can be based on a combination of multiple sensors. This method utilizes fusion algorithms to achieve multi-source information fusion navigation functions with all-weather, anti-jamming, and other characteristics. The aircraft navigation in a cluster can achieve the navigation mode of following a lead aircraft on the basis of the relative information of the leader, which has the advantages of saving resources and dynamically adjusting the formation. In this paper, based on the formation of the lead aircraft and wingman, the relative distance and relative constraints between the formations are designed. For the lead aircraft, the navigation method of multi-source fusion is adopted, while for the wingman aircraft, the tracking navigation method of relative ranging is adopted to achieve the overall navigation function of the unmanned cluster.
