This paper explores the algorithm research and application of RTK UVA calculation technology in sag measurement of transmission line conductors. During the construction and acceptance process of transmission lines

wire sag is an important parameter indicator. Traditional measurement methods suffer from terrain limitations

cumbersome operations

obstructed field of view

and significant errors. By utilizing the flexible flight capability of RTK UVA and equipped with LiDAR measurement technology

high-precision positioning of wire measurement points can be achieved in real-time and dynamically. Based on the theory of longitude and latitude ranging

a parabolic three measurement points and multiple measurement points are used to calculate wire sag. By comparing and analyzing the difference between a line selection coefficient k and its standard value

the narrow range of k value variation is determined to verify the accuracy of wire sag measurement. At the same time

the ideal division of measurement sections using RTK UVA is provided to complete the high-precision wire sag measurement

providing a new solution for wire sag measurement. This technology not only breaks through environmental limitations

improves measurement efficiency

but also reduces the risk and cost of manual measurement

which provides an efficient measurement method for the field of transmission lines

and helps to improve the construction efficiency of transmission lines

therefore providing strong support for the sustainable development of the power industry

which has broad application prospects.
