Research and Design of the Flight Attitude Information Acquisition System for Multi-rotor Small Aircraft

This paper designs flight attitude information acquisition system for multi-rotor small aircraft, which has a variety of flight attitudes, including flying height, rotor speed, three-axis acceleration speed, and three-axis angular velocity. The flight attitude can be well controlled under the designed acquisition system based on ARM7 microcontrollers. Communications between the flight attitude information acquisition system embedded on the aircraft and the host computer can be realized by the wireless module. 3D display interface can be applied to show all the flight attitude information in the host computer comprehensively. The test results show that the designed flight attitude information acquisition system has a good performance.
