Behavior Trees for Mission Management of High-Altitude Pseudo-Satellites

High-altitude pseudo-satellites currently require large crews of highly trained personnel. In order for these platforms to become commercially viable, it is imperative that mission-level tasks are automated in a mission management system, while maintaining flight safety. The new method of behavior trees is investigated for this purpose and extended with proper initialization, continuous-time processing, and modular stateful tasks. The approach is implemented in the Modelica environment and evaluated in a complex mission Simulation.
