Polarization Navigation Simulation System and Skylight Compass Method Design Based upon Moment of Inertia

Figure 1

The basis of polarized skylight navigation. (a) Polarization-sensitive dorsal rim area (DRA); (b) DRA ommatidium, the ommatidial microvilli are arranged in different angles. The microvilli of photoreceptor 1 are perpendicular to those of 2, 3, 4, 7, and 8. And microvilli of photoreceptors 5 and 6 are oriented irregularly; (c) the Rayleigh sky model, where the yellow point represents the Sun, the red line is the SM-ASM, double arrows are E-vectors, and the blue lines indicate the degree of polarization (DOP). The thicker the blue line, the greater the DOP.
