Three-dimensional Trajectory Tracking System Based on Compass and Gyroscope

According to the high-precision positioning capability with Beidou navigation and the angular momentum conservation of gyroscope, this paper presents a real-time trajectory tracking system based on embedded wireless three-dimensional space. The system used by the application which based QT-cross-platform C ++ graphical user interface. And it is used the OpenGL to achieve real-time trajectory record and precise positioning. And data integration use of Qlite database technology. Experimental results show that simulation results of this system basically consistent with expected results. It has advantages of the long positioning and strong spatial expression.
