Abstract: The novel stratospheric aerostats based on wind filed utilization inherit the merits of high altitude balloons, such as simple structure, mature technology, and low cost. Meanwhile, the control limitations of balloons on trajectory and altitude control could be overcome by introducing a control design. With certain capability on flight trajectory planning and station-keeping, the aerostats have been considered as an important vehicle for near-space application. This paper first reviews the research situations of typical projects, sorting out the key technologies for the development of novel stratospheric aerostats. Then, we focus on the key issues such as stratospheric wind model method, altitude control method, and station-keeping strategies, discussing the feasible solutions for the related problems from the perspective of engineering.

Key words: stratospheric aerostat, quasi-zero wind layer, station-keeping, altitude control, wind field prediction
