| Outline of Final Research Achievements |
Large stratospheric balloons have been used for various scientific missions. Some of such missions recently require more precise attitude control of the gondola (payload part) for better quality of the science. This study aimed to develop the numerical dynamics model of the balloon flight system for the design of the attitude control system, and conducted the direct measurement of the attitude motion during the flights. For the measurement, the special measurement system was developed and was applied to two balloon flight experiments. Then, the structure models of the flight system were estimated based on the flight results.
