一种基于“当前”统计模型的GPS/DR组合定位算法研究

Study on GPS/DR Integrated Location Method Based on Improved Current Statistical Model

针对"当前"统计模型在实际应用中存在的问题,给出了一种改进的"当前"统计模型,并将其应用于GPS/DR组合定位系统的数据融合中。实验结果表明:使用该算法的定位系统无需任何参数的预先设定,即可实现对系统方差的自适应调整,对车辆的各种运动状态进行准确跟踪。

Aiming at the problems of Current Statistical Model ,this paper presents an improved Current Statistical Model used in GPS/DR Integrated Location System information fusion. Experimental results show that the system used this method can carry out the self adoptions of the system variance without presetting any parameter, and track precisely various vehicle motion states.
