The problem of three-axis stabilization and beam-tracking guidance of a thrust-controlled airship without thrust vectoring is analyzed. A comparison is carried out throughout the work, introducing at first stabilityaugmentation and guidance controllers for an existing reference airship, featuring traditional aerodynamic surfaces for control. Then a four-thrusters airship with no aerodynamic controls is presented, and flight controllers for this platform are designed and implemented. The performance of both airships in autonomous flight is assessed in a realistic non-linear dynamics simulator, showing interesting tradeoffs of the two configurations in complex virtual scenarios, in still air or steady wind conditions.
