Swarm flight for UWB-based reference trajectory tracking.The aim of this work was to study and implement techniques to perform two combined tasks: maintaining a stable flight structure of a swarm of drones, and having them track the motion trajectory of an external reference body operating in a GNSS-denied environment.In particular, a potential-based decentralized algorithm was deployed for the swarming task, while a centralized approach was chosen to fulfill the tracking requirement. The studied procedures make use of the GNSS position of the swarm anchors and the relative distance between each pair of vehicles, given by the Ultra-WideBand (UWB) sensors mounted on each machine.The results of the carried out simulations show a good tracking capability, while successfully maintaining a stable group flight configuration in all tested conditions.
