Orientation Method and System for Atmospheric Polarization Pattern

Biological research results demonstrate that insects such as sand ants and bees not only possess the ability to be highly sensitive to polarization information, but also can determine their own movement direction through the distribution of polarization patterns in the sky. The highly autonomous sky polarization pattern is one of the inherent resources in nature, which is basically not damaged and interfered by human subjective factors. It is very suitable to provide orientation information for carriers in the environment of weak or no satellite signals. Consiquently, the orientation method based on the atmospheric polarization pattern has a good application prospect for autonomous orientation. This chapter focuses on the vector-oriented methods and systems based on atmospheric polarization patterns.
