Abstract:In this paper, experiments are conducted in the area of 500 kV and 220 kV high-voltage transmission lines to research the effect of high-voltage transmission lines on GPS observations. The results show that electromagnetic interference and radio interference caused by the high-voltage transmission lines have no significant effect on the internal noise of the GPS receiver. The high-voltage transmission lines significantly impact the multipath effects. The closer to the lines and the higher the voltage, the more serious were the multipath effects. The high-voltage transmission lines have no significant effect on the ability of the GPS receiver to capture the data, the stability of the receiver clock, signal-to-noise ratio of the L1 and L2 carrier, cycle slip of the observation data, and the accuracy of calculation of the baselines and coordinates.
