EFFECTS OF ELECTRIC POWER LINES ON THE ACCURACY OF GPS POSITIONING

AbstractA practical experiment of the potential effects of high voltage electric power lines on GPS satellite signals and hence the received GPS data was performed. In this experiment, a network of 10 stations were precisely established underneath and around 380 kV electric power lines. Then, a static GPS campaign was conducted on the network while the power was shut off. The same campaign was repeated in the next day when the power was turned on. The results of the two days were analysed and compared with each other. The results of this experiment demonstrated that there is no statistical evidence of any degradation of GPS positioning accuracy due to the high voltage electric power lines.
