![]() A small perturbation modeling technique is described in. įor the development of meaningful control and navigation strategies, an accurate dynamic model of the airship is required. Despite significant developments in this field, a lot need to be explored so that lighter-than-air (LTA) vehicles could be used as unmanned robotic platforms. Many efforts have been directed to the development of semi-autonomous vehicles with navigation and control systems capable of executing trajectories on the basis of high level human-planned missions. As a basis, a six degrees-of-freedom dynamic model of a non-rigid airship is required. Successful design of such a system necessitates an accurate model of airship dynamics. ![]() In order to achieve these goals, a robust guidance and control system capable of auto-piloting and controlling the airship flight is required. Major applications include roving or hovering, surveillance and communication utilities for both military and commercial use, plus a variety of remote-sensing instruments for scientific applications. Having their lift by the buoyancy force, these vehicles require much less power than traditional aircraft. Vehicles with lighter-than-air (LTA) concept represent a unique and promising platform for many applications that involve a long-duration airborne presence.
