Most polarized light navigation sensors are designed according to the POL-neuron model.The main error sources are gain difference between channels and the relative angle error.To improve the measurement precision of polarization compass information,we propose an independent channel measurement method of polarization compass information.The atmospheric polarization information is measured by using three independent polarization measurement channels to obtain heading-angle information for navigation.We further design an independent channel polarized light navigation sensor via integrating the time division multiplexing technology,and propose the calibration method and error compensation algorithm.The experimental results show that the independent channel polarized light navigation sensor significantly reduces measurement error of polarization compass information (within ±0.05° after compensation).
