[Example] Centerline and longitudinal survey of high-voltage transmission lines

Introducing the use of network-type RTK in the centerline and longitudinal surveying of high-voltage transmission lines.

We would like to introduce a case study by Haidex Co., Ltd. and Mr. Wajima regarding "centerline and longitudinal surveying of high-voltage transmission lines" utilizing network RTK. In this case, due to the harsh mountainous conditions during the snowfall season, we primarily used network RTK, and in locations where mobile phone communication was not possible or where satellite data was difficult to capture, we also employed a total station. Furthermore, the network RTK was used for multiple sets of observations through single-point observation methods, with a horizontal limit of 2 cm based on the differences between sets, and the average value was adopted. The observation work was carried out relatively smoothly. Additionally, given the conditions of snow accumulation and mountainous terrain, what would have taken approximately 10 person-days (2 people for 5 days) using only a total station was completed in about half the time. 【Solution】 - Utilized network RTK for the centerline and longitudinal surveying of approximately 20 km of high-voltage transmission lines. - Combined the use of network RTK as the main method with a total station. *For more details, please refer to the PDF document or feel free to contact us.
