The concept, present status and basic problems involved in developing a powered station-keeping balloon with moderate payload capability approx. 200 pounds are outlined. The POBAL balloon will float in the seasonal minimum wind fields 60,000-90,000 feet. By supplying enough thrust to overcome the wind- drag forces, the balloon will be kept hovering above a designated location for a duration limited by its fuel supply. The feasibility, choice of balloon design, predicted durations for candidate propulsion methods and other pertinent considerations are discussed. A demonstration flight system using available system components is described. The eventual POBAL capability is contrasted with that of drones and several immediate applications for an operational POBAL system are described.
