3-D Positioning for Drone-Based Spatially Reconfigurable Phased Array

This study presents a 3D positioning method to enable precise phase synchronization among individual drones, which is the key for the drone-based spatially reconfigurable phased array [1]. The proposed system eliminates the dependency on GPS by enabling drones to locate each other as a cohesive unit. By employing a hierarchical structure consisting of leader and subleaders, coupled with an iterative method among drones, precise phase compensation is achieved.
