摘要

为了实现绝对航向角度获取,提出一种基于简化太阳方位角的绝对航向角解算方法。通过输入观测地的位置信息和观测时间信息,得到太阳赤纬角和太阳时角,从而计算出地理正北坐标系下的太阳方位角。再利用天空的偏振分布特性,结合基于太阳子午线提取的偏振光导航定向算法,可以解算绝对航向角信息,以实现导航的目的。计算机仿真和外场实验结果表明:太阳方位角的均方根误差<0.01°,室外静态航向角解算的均方根误差<0.2°,动态航向角解算的均方根误差为0.53°,基本满足多数场景下导航的测量精度要求。

Abstract

To acquire the absolute heading angle, an estimation method based on the simplified solar azimuth is proposed. By inputting the position information of the observation place and the observation time information, the solar declination angle and the solar time angle are obtained, so as to calculate the solar azimuth angle in the geographic due north coordinate system. Then, based on the polarization distribution characteristics of the sky, the polarized light navigation and orientation algorithm based on solar meridian extraction is used to obtain the information on the absolute heading angle, so as to achieve the purpose of navigation. The results of computer simulation and field experiments show that the rms error of solar azimuth is less than 0.01°, the rms error of the estimated outdoor static heading angleis less than 0.2°, and the rms error of the estimated dynamic heading angle is 0.53°, which basically meet the requirement of the measurement accuracy for navigation in most scenarios.
