摘要
移动通信和定位技术的结合,是当前通信市场一个新的业务增长点。文中结合UWB定位系统的特点和优势,设计了一种实用的UWB多点协同精确地理定位系统方案,并用一种简单有效的算法来验证其定位精确度。通过实测数据计算目标位置,说明在多个UWB收发机协同定位时能达到厘米级定位精度。该方案实现简单,可移植性强,具有一定的实用价值。
Currently, to combine telecommunication with location techniques is a new service rising point. This paper designs an applied TDOA-based multi-points cooperation Ultra Wide band wireless location system integrated the characteristics and advantages of UWB location. Then a time-difference-of-arrival (TDOA)-based algorithm is introduced. The measurements and computed position show this scheme has an accuracy on the centimeter scale. The scheme has a fine applied value and can be easily completed and used in other fields.
