      Article
      Open Access
      Unmanned Air Systems (UAS) navigate using Global Navigation Satellite Systems (GNSS), but GNSS vulnerability precludes its use as the only means of navigation and requires a secondary means of navigation. A differentiating ...

    • Mission formalism for UAS based navaid flight inspections 

      Santamaria Barnadas, Eduard; Pérez Batlle, Marcos; Ramírez Alcántara, Jorge; Barrado Muxí, Cristina; Pastor Llorens, Enric (2009)
      Conference report
