Anhong Tian · 2012
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 highrise 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.
