由於無人飛行載具有重量輕、機動性高和可彈性運用等優點，其應用範圍和領域逐漸擴大。目前在無人飛行載具的控制技術上，為了使載具更加穩定，甚至達到半自動、全自動飛行的控制，載具都會搭配姿態儀和GPS回饋姿態和位置、速度等資訊。而市售的姿態儀除了價格昂貴並且沒有整合GPS，若結合所有感測器和控制核心，整體系統就會變得複雜且體積龐大。此外，市售的姿態儀並不一定能滿足控制需要的規格和抵抗載具震動的干擾，因此本研究的目的在於自行研發運動感測系統，以提供控制無人飛行載具需要的資訊。
在此研究中，使用Microchip 32位元的微處理器，結合加速規、陀螺儀、磁力計、氣壓式高度計和GPS各式感測器，並應用本研究建立的數學模型，實現運動感測系統的研發。

Because of the advantage of light weight, high mobility and flexibility, the range of applications for unmanned aerial vehicle are expanded gradually. In order to increase stability of unmanned aerial vehicle or to achieve semi-automatic and automatic control, it is usually use AHRS(Attitude Heading Reference System) and GPS(Global Positioning System) to feedback information of attitude, position and velocity. However, AHRS is very expensive and probably not fit the specification of control. Moreover, the whole control system becomes complicate and needs more space when it has to integrate all sensors and control unit. Therefore, it has to develop a motion sensor which can overcome the disadvantage of the above and provide the information of UAV to the control system.
In this research, it uses 32 bits microprocessor of Microchip and integrates gyroscope, accelerometer, magnetometer, barometric altimeter and GPS to apply the mathematic model built in this research.
