A Novel Polarized Light Compass Aided By GPS Module

This paper proposes and designs a novel bionic polarized light compass with the aid of the microarray polarized camera. The compass contains a small Global Positioning System module to assist orientation. The algorithm uses the Principal Component Analysis method to fit the solar meridian, and combines the astronomical calendar method to output the heading angle of the carrier in real time. The Root Mean Squared Error is 0.48 ° under dynamic conditions and 0.18 ° under rotation conditions, which has achieved good results in outdoor navigation experiments.
