摘要
知道无人机的位置以及高度是非常重要的。知道无人机的位置就能够调整无人机的飞行过程,从而防止其坠毁,所获得的数据能够在地图上显示无人机的位置。要计算目标飞行器的位置,知道其海拔高度也是必要的。本文为四旋翼飞行器选择一种合适的定位方法,将GPS和气压计结合在一起,GPS传感器是用于在水平平面内的定位,而气压计则用来确定飞行器的海拔高度。该方法已经在派诺特AR.Drone飞行器上进行了测试,实验和仿真结果表明能够满足设计要求。
It is important to know the position （including the altitude） of the UAV. By knowing the position, it is able to prevent crashes by adjusting the course of the UAV. The data which is obtained could display the loca- tion of the UAV on a map. In order to know the altitude,calculating the position of the object is necessary as well. The aim of this paper is to select a suitable positioning method for quadrotor aircraft. The method has been tested on a Parrot AR.Drone. In this paper the selected positioning method uses the combination of a GPS sensor and a barometer. The GPS sensor is used for positioning in the horizontal plane while the barometer is used to determine the altitude. The results of experiments and simulations show that the selected positioning method can meet the de-sign specifications.
