摘　　要：研究了GPS定位系统在货场龙门吊定位中的应用.通过分析龙门吊在行驶过程中本身存在着的一些约束条件,提出以龙门吊轨道的直线方程作为定位滤波的约束条件,建立了带轨道约束条件的系统模型,并推导出了约束条件下的卡尔曼滤波方程.实验结果表明该研究提高了差分GPS的定位精度,实现了对龙门吊的准确定位.In this paper,a research on the application of GPS system in the positioning of RMG in goods yard was done.By analyzing a RMG moving constrained by its rail,that the line equation of the rail would be considered as the constraint of the filter was proposed.Then a system model with constraint conditions was built and a Kalman filter formulation was also deduced.The result of experiments shows that the theory above could enhance the positioning accuracy,realizing the RMG positioning accurately.
