Typical applications, such as georeferencing, long travelings, and monitoring, can be executed by unmanned aircraft squadrons by assuming different formations, such as latitudinal and longitudinal formations and circular motion maintenance, respectively. In order that all these problems can be solved in one mission, the squadron must reconfigure itself among these different formations in an autonomous way. In this study it is proposed a multifunctional missions execution scheme for unmanned aircraft squadrons based on geometric formation reconfigurations. The problem is a multidisciplinary one, and addresses the following issues: A control strategy able to deal with the aircraft model nonlinearity; computational algorithms for reconfiguring the squadrons among its different formations, whose efficiency is not critical for real-time applications; a theoretical treatment that allows the proof of convergence among the several squadron formation reconfigurations, and an approach that contributes to the system robustness with regard to parametric uncertainties of the aircraft dynamic model. Solutions are presented for the sub-problems and it is proposed their integration for getting a scheme for running a multifunctional missions queue.
