Obtain the Solar Direction by the Skylight Polarization Degree Measurement

Lei Li, Jun Zhou, He Huang

Abstract

Skylight polarization pattern is used as an important navigation clue for desert ant and bees. The paper will present a new solar direction extracting method based on the polarization degree measurement. Two kinds of solar direction calculation model will be derived, one is by the polarization degree measurement of two observation directions, the other one is by the polarization degree and polarization E-vector direction measurement of the same observation direction.
