INS/GNSS/Polarized Light Integrated Navigation System Based on CKF

Polarized light navigation is a popular navigation method in recent years, but the polarized light sensor cannot be used alone. To improve navigation accuracy and efficiency, this paper introduces a CKF-based INS/GNSS/Polarized Light integrated navigation system. In this system, GPS provides longitude and latitude for the inertial navigation system, and time and initial longitude and latitude for the polarized light system, which maximizes the use of information. This paper evaluates the proposed method by collecting the measured data. The experimental results showed that the output accuracy of the proposed system was improved by 41.5 and 26.7% compared with the traditional navigation system.
