摘要
本文介绍了移动电话定位的核心技术———TDOA(TimeDifferenceofArrival)技术的内容及性能以及TDOA技术同其它时差定位技术的比较 ,并与GPS(GlobalPositioningSystem)和AOA(AngleofArrival)定位技术进行了比较 ,最后进一步阐述了移动电话定位技术的应用及其在中国的应用前景。
This paper describes a new position technology—cellular phone position technology. The content and property of the key technology of cellular phone position—TDOA(time difference of arrival)technology is introduced. TDOA technology is compared with the other technology of time difference position. The cellular phone position was compared with the GPS(global positioning system) and the AOA(angle of arrival)position technology. At last, the application of cellular phone position and its prospect in China is expounded.
