Study on skylight polarization patterns over the ocean for polarized light navigation application
Applied Optics, 2018Polarized skylight navigation has excellent navigation performance with no error accumulation over time and low susceptibility to interference. The skylight polarization distribution contains rich directional information, such as the solar meridian, the neutral point, and the polarization angle, which plays a key role in the polarization navigation ...

Attitude Determination Based on Location of Astronomical Markers With Skylight Polarization Pattern
IEEE Sensors Journal, 2015Many social insects, such as desert ant and honeybees, are able to utilize the natural skylight polarization information for navigation, which has advantages in immunity to the interference of external environment and thus shows higher stability and accuracy. Inspired by it, we attempt to explore a new bionic method for attitude determination by use of

Dynamic patterns of skylight polarization as clock and compass
Journal of Theoretical Biology, 1980Abstract Although many animals use the polarization of skylight for directional orientation, most investigations have been limited to consideration of the static relationships between E-vector orientation and the sun's azimuth. Much more useful information is directly available to any animal that could utilize the dynamic properties of skylight ...

Simulation of the polarization pattern of skylight affected by mineral dust aerosol particles
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016Atmospheric aerosol has important influences on the global climate either directly by scattering and absorption of the solar radiation or indirectly by affecting cloud droplet concentration or cloud radiative properties[1–2]. A high proportion of aerosol in the Earth's atmosphere consists of non-spherical mineral dust particles[3].
