【摘要】 针对利用自然偏振特性的自主导航——仿生偏振导航,天空偏振光分布模式与载体的地理位置及航向间的映射关系,研究不同天气条件下的仿生偏振导航测量误差情况,提出利用测量误差参数值修正系统测量误差。对导航定位而言,测量计算的精度对于导航定位是至关重要的。对不同天气条件下,多导航单元进行方位角测量,利用云计算对大量的测量数据进行仪器误差和随机误差分析,进而得到误差参数值,为提高仪器的测量精度提供评估依据。更多还原

【Abstract】 Bionic polarization navigation is an autonomous navigation method that uses natural polarization characteristics.There is a relationship among distribution pattern,position and heading angle of navigation unit in different weather conditions.This paper proposes a method to correct the system error by using measure error parameters.The accuracy of measurement is critical to navigation.This work focuse on the surveying of azimuth angle under different weather conditions.Then we use cloud computing to analyze the system error and random error of the measured data and acquire the error evaluation parameters.The results provide the evaluation basis for improving the surveying accuracies.更多还原
