Integrated navigation system for UAVs based on the sensor of polarization

摘要

To meet the necessary of autonomous navigation, a novel attitude determination method by using an INS and a polarization sensor was proposed. The mathematical model of the polarization was analyzed. An explicit complementary filter (ECF) was designed to make a good use of the polarization sensor and the INS. To examine the validity of the designed integrated navigation system, the designed system was tested under static and dynamic conditions. Experimental results show that the ECF providing the precise attitude angle of an unmanned aircraft.
