Abstract

In the traditional ultra-wideband (UWB) positioning technology, the influence of the ranging error on the positioning model and the influence of the motion parameters of the moving object on the positioning accuracy are not considered, especially for high-speed moving objects, it is difficult to achieve real-time, stable and exact positioning. Therefore this paper proposes a ranging calibration algorithm to minimize the distance error. The algorithm constructs a cost function based on the distance error, and combines the acceleration gradient descent (NAG) method to screen the value of the large distance error in the cost function. For the positioning of high-speed moving objects, the speed parameters of the moving objects are introduced, the vector equations about the anchor and the moving objects are established, and the positioning solution model of the moving objects is obtained, so as to realize the precise positioning of the high-speed moving objects.
