Research on Bionic Polarization Direction Orientation Algorithm and Polarization Navigation Technology

Based on the standard atmospheric polarization model, the principle of bionic polarized light orientation is studied, and the formula of solar height angle and azimuth angle is given. Then the calculation method of polarization degree and polarization azimuth angle is studied. The method of calculating the heading angle when the carrier is tilted is deduced. The results show that if the horizontal angle of the carrier is known, the heading angle of the carrier can be calculated according to the polarization angle. Because the polarized light sensor can only give the heading information, the microelectromechanical system MEMS and the polarized light sensor combined navigation system are given. It is pointed out that the method of polarized light combined navigation can greatly improve the performance of the system and have a wide application field.
