Abstract
Traditionally, the GPS coordinates of a transmission tower have been measured at the center of the tower on the ground, which usually takes dozens of minutes. However, this method often produces errors of tens of meters or sometimes demands several hours due to signal interference from the huge steel structure of the tower. To solve this problem, in this paper, a new measuring method for GPS coordinates of steel towers is proposed. First, instead of measuring the center of a tower, four GPS coordinates of the edges of the tower are obtained by using a measuring device with three GPS modules, and then are averaged to find the center of the tower. When a measured value is deviated considerably by signal interference, a newly proposed algorithm filters out such an inaccurate coordinate, effectively calculating the center of the tower by using other edge coordinates. Through field tests, it was confirmed that this new algorithm could improve the task efficiency and its measuring accuracy for GPS coordinates in a GPS interference environment.
