摘要
为了满足偏振光天文导航定位对高精度太阳空间位置信息的需求, 提出一种基于瑞利大气偏振模式的太阳自主定位方法。实验结果表明, 该定位方法能够获取太阳相对可靠的地理位置信息, 且经、纬度误差均值分别为0.251°和0.171°。虽然该方法的定位精度有待于进一步提高, 但其作为其他定位方式的补充有着重要应用价值。
Abstract
In order to satisfy the requirement of the polarized light celestial positioning for the high-precision solar spatial position, one method based on the Rayleigh atmospheric polarization pattern is proposed. The experimental results indicate that, this method is capable of obtaining relatively reliable geographic position information with an average longitude error of 0.251° and latitude error of 0.171°. Although the precision of this method needs to be further improved, this method possesses important application value as a supplement to other positioning methods.
