| 摘 要： | 针对难以通过全球卫星导航系统(GNSS)直接测量的目标点位动态标定问题,讨论了GNSS双天线姿态确定的方法,且对存在的由安装误差等因素引起的姿态不一致做了推导分析,提出了一种基于GNSS双天线的点位动态标定原理和试验验证方法,并对点位动态标定的精度进行了分析．通过飞行试验算例分析得出:该方法可实现优于3 cm的动态标定精度,为载体目标点位动态标定提供了一种新的解决方案．

| Abstract: | In this paper, a method of GNSS dual-antenna attitude determination and the existing pose inconsistency which caused by installation error or other factors have been analyzed.At the same time, a point dynamic calibration method based on GNSS dual antenna and an experimental verification method have been proposed to solve the dynamic calibration of target points for difficult measurements directly through GNSS, and analyzing the point accuracy of dynamic calibration. The flight test example shows that the method can achieve dynamic calibration accuracy better than 3 cm, and provides a new solution for dynamic calibration of carrier target points. |
