Real-time sky polarization mode measurement above 60 FPS is achieved using novel IMX250-MZR micro polarized array chip. On this basis
sky polarization angle distribution image is redrawn according to the new reference coordinate system
and the heading angle is accurately obtained by extracting the symmetry axis of the sky AOP distribution image. The experimental results show that the heading acquisition precision exceeds 0. 1°
and the system real-time navigation frequency in the MATLAB environment is higher than 20 Hz.
