| 摘 要： | 目前，定位某个目标一般采用的是GPS定位技术，但是GPS定位技术需要至少接收到4颗GPS卫星信号，才可以确定目标的位置，当某目标运动到室内或高楼耸立的大城市中时，因为受到高楼的遮挡，使得接收机因接收不到卫星的全部信号而无法完成对目标位置的准确定位．为解决这一问题，文章研究了基于数字电视信号（DTV）的定位技术，利用电视台发出的数字电视信号辅助GPS进行联合定位，从而实现目标的无线定位跟踪．、

| Abstract: | GPS technology is commonly used to locate a target, while GPS technology can only determine the location of the target by receiving at least four GPS satellites signals and when a target moves indoors or high- rise towers in large cities, the exact location of the target can not be completed because the receiver can not receive satellite signals. To solve this problem, the paper studies positioning technology by the opportunity digital television signal （DTV） and puts forwards the combination method by which GPS wireless location tracking can be completed with the help of digital TV signals. |
