The method of determining the spatial attitude of the aircraft within the atmosphere using natural light polarization modes

The method of spatial attitude of the aircraft in the atmosphere using natural light polarization mode is determined. The present invention relates to a navigation technology, in particular to a three-dimensional attitude determination method for polarizing the atmosphere. The method is implemented using the following steps: (1) On-line real-time acquisition atmospheric polarization mode using a spherical sensor array; (2) the collected atmospheric polarization mode as the original data of a three-dimensional model of attitude determination, the data analysis obtained by using the meridian sun the angle between the sun and the body axis at the projection center position coordinate system of the body; (3) determining a yaw angle using a radial angle to the body axis; (4) using the calculation formula evaluation attitude pitch angle and roll angle. The present invention has reasonable design, three-dimensional polarization mode using atmospheric attitude determination, provides a good technical means, having a characteristic completely independent, real-time detection by the atmosphere polarization mode distribution, it can be calculated by its own three-dimensional posture, simple and feasible no accumulated error, while the visible light in the polarization information present in the atmosphere, a large area is difficult to artificially interference and damage.
