The method of the navigation direction angle acquisition based on the symmetry detection of the atmosphere polarization mode

With the technological and social development, navigation science based on natural features, receives wide attention, and has important research and application value. For the acquisition problems of navigation direction angle in the bionic polarization navigation technology, in this paper, a method is proposed to acquire the navigation direction angle based on the symmetry detection of the atmosphere polarization mode. This method is established on the base of the analysis of the atmosphere polarization model distribution. Using the symmetry of the distribution of atmospheric polarization mode and according to the test results of the symmetry, the radial position of the sun is determined, and then the navigation heading angle information calculate is calculated. At last, the corresponding experiment is also given to test the method of navigation direction angle acquisition based on the symmetry detection of the atmosphere polarization mode. The method of the navigation direction angle acquisition based on the symmetry detection of the atmosphere polarization mode, is very important in the research of bionic polarization navigation, and has the important practical significance for the Navigation methods and strategies based on natural characteristics.
